  1. I am currently setting out to figure out how to add factory front and rear park assist. I've spent quite a bit of time researching and looking through the upfitters manual to try and figure out if and how I might accomplish this. I can say that this is a very expensive and time consuming upgrade....especially since both front and rear bumpers need to be replaced. There are several parts that need to be added and quite a few circuits that need to be added. From looking at my X61A junction box, there are several circuits missing, and I have confirmed that the park assist module and cluster will need to be programmed after exchanging emails with WAMS (White Auto Media Services). We are both unsure if the BCM will require programming. I am thinking that it may not be necessary for this mod. Vehicle: 2018 Silverado, Crew Cab LT All-Star Edition 5.3L Parts Needed: 13447860 Control Module 19115653 Connector (You Wont Believe how expensive this is...but it comes with pre-terminated leads) 15127038 Connector & Terminal Part #: SAIT-A03T-M064 13525987 Connector & Terminal Part #: SAIT-A03T-M064 23145170 Stab Control Switch (Dash Switch to add park assist button) Terminated Lead Part #: 13575782 84029812 Front Bumper w/Fog Lights w/Sensors 84153946 Front Sensor x4 23276805 Park Sensor Bracket Front x4 23274031 Harness 23108141 Rear Bumper w/Sensors 23428268 Rear Sensor x4 23276807 Park Sensor Bracket Rear x4 23406458 Harness The bumpers are very expensive as you can imagine, so I am still trying to source new OEM chrome bumpers. I may break down and buy OE replacements on Ebay as they are much cheaper. Same part numbers are used. Circuits Needed to be Added: 3140 - Battery Positive Voltage 5852 - Rear Park Assist LED Disable Signal 5060 - Low Speed GMLAN Serial Data (I believe this circuit may already exist. Need to verify) 2751 - Signal Ground (This circuit may already exist under the passenger seat) 2375 - Left Rear Corner Object Sensor Signal 2376 - Left Rear Middle Object Sensor Signal 2374 - Object Sensor Control 2378 - Right Rear Corner Object Sensor Signal 2377 - Right Rear Middle Object Sensor Signal 2379 - Object Sensor Low Reference 5213 - Front Parking Left/Right/Mid Sensor 5215 - Front Parking Left Corner Sensor 5216 - Front Parking Left Mid Sensor 5214 - Front Parking Sensor Low Reference 5217 - Front Parking Right Corner Sensor 5218 - Front Parking Right Mid Sensor Various Colors of 22 awg cross-link TXL Wire 1/2 in wire loom Tesa Wire Loom Harness Tape Replacing Bumpers: Replacing the front bumper is pretty straightforward and is laid out very well in Phil Gamboa's youtube video. The harness' will need to be replaced with the parts listed above. I recommend swapping out the harness' while the bumpers are off. The rear bumper is a pain. You will need to loosen 8 bolts that attach the bed to the chassis. There are a few videos on how to do this. The bed does not need to be removed - It can either be propped up inside the wheel wells or held up by 2 people on either side while the bumper is lifted off. The bed needs to be lifted in order to fit the bumper brackets underneath it when pulling away from the vehicle. You can replace the brackets and plastic parts on the rear bumper. It is pretty straightforward. Just squeeze the tabs one by one with a pair of pliers and they will release. If you pry the top plastic step without squeezing the tabs, you may break off the tabs. Front Park Assist Sensors: Phil Gamboa has done a great job showing how this is performed in his youtube video that shows him adding front park assist Rear Park Assist Sensors: Phil Gamboa has done a good job on explaining how to add front park assist. A nearly identical process is required to add the rear but instead the circuits will go to the X138 Connector under the hood and can be lead into the cab on the driver side much like how PGamboa did on the passenger side for the front sensors. From the upfitters manual it looks like the rear sensor wires go from sensors->harness->X185 Connector->X138->X2 Control Module Connector. I have not yet been able to locate the X185 Connector (most likely under the bed somewhere), but think that I will end up bypassing it and going straight to the X138 connector. Control Module X1 Connector to Instrument Panel: The X1 Connector Circuits will run straight to the X61A Junction Box under the driver door sil. Power and Ground from the X1 Connector look like they will run up the passenger door sil. Circuit 3140 - Battery Positive Voltage Lands in the X51R fuse block in the X1 Connector, in cavity #43. I landed the Ground lead using a ring terminal under the B pillar. There is a ground bolt down there. Current Holdups: Finding where exactly to land circuit 3140 - Battery Positive Voltage. Circuit 3140 actually lands in the X51R fuse block. X1 connector, terminal #43. Finding terminals for connectors has been very very difficult and I am still looking for several different types. I am having a difficult time finding the correct terminals for: S45A Multifunction Switch -> Ended up purchasing the GM terminated leads. Part #: 13575782 X61A Junction Box X1 Connector -> Mouser Part #: 829-35031567 X61A Junction Box X5 Connector -> Mouser Part #: 829-35031567 X150 Connector Male -> Mouser Part #: 571-964265-2-LP X150 Connector Female -> Mouser Part #: 571-964263-2-LP X901 Connector Male -> Mouser Part #: 538-33000-0002-LP. After landing the terminals, I cannot get the connector to seat properly and lock, but I have confirmed that all wires have continuity through the connector. I am still working on figuring out why this is happening. X100 Connector Female -> Mouser Part#: 538-33012-2003-LP Any help with figuring out terminals for where to find decently priced bumpers would be appreciated. I am continuing to work on the project as time permits. I am almost done with the modification as of now 8/27/19. I am waiting on a few park sensors to arrive to replace a few bad ones that I ended up with. I am getting a "Service Park Assist" Message on my cluster. I will follow up after I have this resolved to confirm everything is working as it should. -Brandon Wood
  2. Have had my truck 2 weeks now, and have rigged it out for work with a Decked unit in the bed, 60gal aux tank, luverne grip steps, and a ranch hand legend grille guard. Initially the outfitters put the wrong guard on it, so they ordered me the one for trucks with park assist and now that it is on, I get intermittent full blown "DUDE YOU'RE HITTING SOMETHING RIGHT THIS SECOND!!" warnings from the two middle sensors. It never fails it's when I'm sitting at a stop light expecting it the least and it scares the hell out of me, annoys during phone calls (im on the phone a lot while driving for work), and just... screw that. Anyone else have this issue resolved?
  3. 2014 GMC Sierra slt My service park assist and service airbag came on at the same time. I took it to the dealer and they said a bad front sensor (2nd one from driver side) was causing both of the alerts and wanted $700 bucks to fix it. I ordered the sensor and replaced it myself but the alerts aren't going away and the park assist system still doesn't work. Any ideas on if I need to do something else?
  4. I realize there are other threads on this topic but none seem very recent. Does anyone have any idea if a 2018 LTZ crew would be pre-wired for at least the rear park assist? That is the only feature of the LTZ plus package I miss so far. My truck was 3 days old to me, with 124 miles and I damaged my rear bumper backing into one of my own cars in driveway. Since I Need to replace out of pocket I am finding its not much more to purchase an assembly with park assist sensors and wiring. However, Im not sure if I would need wiring to go from rear of truck to module location under passenger seat (if I understood location correctly) . In my past experience GM does not like to include a single connector they dont need to regardless of what trim level the vehicle is. Thanks!
  5. My 2011 Tahoe shows park assist off and stereo dead. No chimes, onstar, bluetooth, etc. It came back on once but now everything is dead again. Tried disconnecting battery & checked / pulled all related fuses. Only power I get to stereo is backlight. No clock or sound. Tried EVERY button. Park assist button just flashes. PLEASE HELP!
  6. I need some help! I have a 2008 Chevy Avalanche. I’m having a problem with the back up sensors or park assist. For the past two months when i get in and start the truck, the display on my dash keeps telling me that the park assist is off, but I didn't turn it off. The light will be lit up on the button continuously. Upon pressing the button it will flash at me and remain turned on. I purchased a new ‘Combo Switch (GM part #22778094)’, and installed it, thinking that the button was the problem. However, after replacing the Combo Switch, the light illuminating the reverse sensor, remained on, indicating that my reverse sensors were not operable. I have placed my truck in reverse and checked my sensors and I hear no noise emulating from them, i.e., ticking or something of that nature. I hear absolutely nothing! So how do I continue to troubleshoot the problem? Is there a possibility that: 1) all of my sensors are inoperable OR 2) when one sensor is inoperable, does that make all of them inoperable? Thanks for your time.
  7. I have a 2010 silverado that has had its park assist "serviced/repaired" twice before now. I now have the message again and I'm sick of it. It says that there was a short to battery on sensors 2 and 4, so I replaced them. Then it has a code for short to battery for sensor 1, so I replace it. Then it tells me that sensor 1 is incompatible equipment and now its throwing codes for short to battery on every single sensor... I was told that it might be the "object detection module" but im not getting a code thrown for it... please help, I am a college student and I don't have time to be wasting or the money
  8. 2011 GMC Sierra 1500 This week my park assist stopped working, which is a shame as I actually use it and like it. The message I get is "Service Park Assist". I have read this: http://www.gm-trucks.com/forums/topic/124501-what-happened-to-the-lights-for-the-back-up-sensors-on-11s/ and this: http://www.silveradosierra.com/electrical/reset-reverse-parking-sensor-t114017.html and I have watched some youtube videos. So far I have done the following: 1. Turn on engine, put vehicle in reverse, turn engine off, keep key in accessories one position. Go out behind vehicle and block each sensor individually with my hand. All four give a soft tick-tick-ticking which indicates they are working. I have checked their positioning and wiring, nothing seems to be out of place, although my bumper is full of sand/dirt so I didn't go crazy. There is a small ding in the bumper above one of the sensors, but I haven't hit anything in the past week that I know of, so I'm assuming it is old. 2. Turn off Park Assist using the button under the radio. Remove positive battery terminal and wait one minute. Replace battery terminal and turn park assist back on. 3. Remove positive battery terminal, remove fuse for TRLR REV (as my wiring diagram says the park assist is on the same circuit as the trailer wiring). Replace battery terminal, turn on vehicle. Turn off vehicle, remove terminal, replace fuse, replace terminal, turn on vehicle. 4. Repeat of 3 only with BCKUP fuse instead. Drive in forward over 40 km/hr before trying to reverse again after resetting. None of these things has changed anything. I still get the message to service the park assist. I haven't removed the sensors and cleaned everything up and re-attached them to ensure everything is sitting/attached correctly yet (as wildchevy suggests in the second forum link above). I've thought about just replacing the sensors to see if that fixes it, but they seem to be working. Lordco doesn't carry replacement sensors. The GM dealership quoted me $221.68 PER SENSOR (cue hysterical laughter and hanging up the phone). but I can get a four pack on amazon for $60. I have half a mind to just install an aftermarket wireless backup camera for $80 and be done with it. Anyone have any other bright ideas? Should I just take it into the shop and pay for their time to diagnose it? Cheers.
  9. Service park assist / service traction control / service stabilitrack/ battery power low. All kicked on this morning. Drove it yesterday, start up sounded a bit weak, drove it for like 20 mins. Turn the key over this morning, I get a single click and all the reads out from the above. It's a 2012 Silverado lt with 56k miles on it. It's only been getting started every three days for the last 2 weeks since I've been on vacation. So I'm not sure if the battery died because it didn't get the altanator going enough to generate a charge or what... Really confused. I'm really hoping the damn thing just did all wanna crap out on me at once. Hoping for you help, thanks.
  10. This weekend I drove about 300 miles to trade in my 2011 Silverado (LML) for a 2015 Silverado 2500 LTZ Duramax that I thought I had found a great deal on. Against my better judgement, I decided that it was once again ok to purchase a vehicle that was "new and improved" for that year. I had nothing but trouble with my 2011 with transmission issues and DEF/DPF problems CONSTANTLY. Anyway, I got to the dealership in OK and got all the paperwork behind me. As I was driving home I noticed that the Drivers assist would sometimes beep and other times vibrate. I thought that was strange because I had the setting on vibrate, as the beep gets annoying after a bit. Long story short, the intermittent vibrate/beep is getting worse and the vibrate hardly works at all now. The light that says "Service Driver Assist" comes on repeatedly (5 times on my drive home), especially if i get close to the road lines. So, now I feel like I am screwed because the dealer says I need to bring it to them because it is just out of the 36k mile warranty but they are 300 miles from me!!! My last Silverado almost "drove" me into the arms of a Ford or Dodge and I am afraid that this one is definitely off on the wrong foot. That's saying a lot from a guy that has driven only GM and is a 3rd generation GM believer. Does anyone have advice or has anyone seen this problem on their Silverado or Sierra? Any advice is greatly appreciated! -Todd
  11. 2008 Silverado. I've tried new sensors, new wiring harness and new park assist module. Info center DOES NOT say "service park assist" or "park assist disabled". There's the red flashing light on the indicator(no yellow) in the back passenger corner of cab but no chime/chimes while backing or nearing an object. Any ideas short of a dealer visit???
  12. I found some threads on completely disabling the Ultrasonic Rear Park Assist by removing a fuse then unhooking the battery for about 5 minutes to re learn the computer. I couldn't find anything about making it default to off. I don't want to completely disable it but I would like to have to turn it on to use it. It gets really annoying hooking on to things around the farm and pulling trailers when I get the damn beeping and the stupid message on the DIC. I want it available for certain parking situations but don't want it to be on by default. Anybody have any ideas? 2014 2500HD LT Crew Thanks
  13. I have a 2010 Sierra 1500 4x4 with 21,000 miles. The park assist quit working. When pressing the button under the radio, it does not light up ever, but the display briefly show "Park Assist Off". I check the parking brake, there is no trailer hitch and tailgate is up. There use to be a beep upon shifting to reverse, but not any more. Nothing. Any ideas?
  14. I have a 2013 Silverado LT, would I be able to have the park assist installed?
