Why is it that my key FOB can reach my 2017 LTZ-Z71 Silverado Midnight 1500, but when I try to remote start my truck it does not seem to reach.

 

Example: I Push the lock Icon once (lights flash), hold down the Remote start button, and hold for approximately four seconds (lights flash again), and it will start, SOMETIMES. Sometimes it does not start, but the lights will flash when I hit the lock button...

 

Is this common? Seem like if the FOB can reach the truck, it will do any function it should.

Try holding the key fob under your chin and press the start button I heard about this along time ago and it works trust me I do it with mine all the time when the truck is to far away from the fob to get a signal, hold it under your chin touching the bottom and it increases the range of the signal iam not BSing you. If you don't believe search it on Google.

Yeah, I know that one from the '80's when I was a kid. but, thanks though. I was hoping that I could get an answer that would solve why the range sucks so bad. I read back in to 2014 range and found that some people have gone with Viper, Compustar, or even went with a 2016 battery, and doubled it up (don't sound correct to me). I would have though that over all of these years, they would have tried to knock out the aftermarket by improving themselves. The phone app is great, no doubt about it, but sometimes it's much quicker to use the key FOB...

 

 

I still don't understand why I can lock the truck, but not remote start it...

Onstar app on your phone is an option, but doesn't really sound like what you're looking for.

Sounds like an issue with the truck not the fob if the lights flash with the rvs request.

 

I currently have a '17 rental while my '14 is in the body shop. I noticed that it doesn't rvs at times just like yours. I'm guessing their is an issue with the bcm as that is the module that is responsible for the rvs request.

 

Try your second fob to make sure it's not a fob issue just in case.

Sorry to bring this back from the dead, but did you ever find a solution to your problem? I have the exact same issue on my 2015 LT Silverado. I could lock/ unlock it from across a Walmart parking lot, but the remote start is a different story. I’ve got 3 fobs, 2 GM, 1 aftermarket, all with brand new ultimate lithium batteries, and the range flat out sucks. I’m thinking mine could be a loose wire at the RCDLR module that receives the signals then sends request to BCM.

      Sure, but they do have some affordable options like the Trax, Trailblazer, Envista, and Encore. Some of these have a cheaper base price than the Civic, though the fuel economy isn’t as high. The main problem is that people WANT the highest trim with all the goodies and finance for like 7 years. That’s how ppl “afford” the more expensive vehicles.

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.
