  1. @jimbigg - You have to flip the small flap on top of the cable up. Just be careful not to break it off, once flipped directly up away from the board, the ribbon easily slides out. @Nicholas Trifiletti - Thanks a lot man. Appreciate the thanks. I'm so glad it's saving other people time and money. If my front screen dies (still on stock flipped cable), I'll take a video how to and post it on youtube, then share here to answer any possible questions others might have.
  2. Just disassembled my third row screen again today after receiving my replacement ribbon cables. R&R'd in under 10 minutes and am back up and running! I should go back through my original post and circle the screw locations requiring removal. To split the screen cover, I used my pocket knife to separate, keeping pressure pulling apart and working my blade around the perimeter.
  3. I attempted this repair again, but on the third row screen in our '15 Yukon XL Denali... nada. Was forced was to order the 20pc replacement pack on Amazon and praying it works. GM REALLY needs some serious QC changes.
  4. My 2015 Yukon XL Denali is the same way. The attached image is after paying for a deep cut and buff. Couldn't cut any further without burning/destroying what was left of the pathetic clear coat. The entire roof of the car is this way also and will need to be repainted. The rest of the car looks okay except a couple trim pieces near the rear windows...

  7. This has been discussed in depth, including getting the media involved. Check this facebook group - https://www.facebook.com/groups/1442101352523016/
  8. Thought this could help someone with the same issue I'm having. My Denali was manufactured, October of '14, so falls under this TSB (but I am out of warranty). Current strut/shock GM numbers are #84157467 (Front) / #23290661 (Rear) for a Z95-packaged LTZ or Denali. Document ID: 4204876 -------------------------------------------------------------------------------- #PIT5429: Rough Harsh Ride - (Jun 1, 2015) Subject: Rough Harsh Ride Models: 2015 Cadillac Escalade Models 2015 Chevrolet Tahoe LTZ, Suburban LTZ 2015 GMC Yukon Denali Models With Magnetic Ride Control Suspension (RPO Z95) Vehicles Built Before 2/10/2015 Attention: Installing the updated suspension components and calibration call out in this PI will NOT provide a ‘sofa-on-wheels’ type of ride, and will NOT eliminate tire/wheel, propshaft, rear axle related inputs/disturbances; they are designed specifically to address the rough, harsh rough/harsh/stiff ride concern. -------------------------------------------------------------------------------- The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition/Concern The new 2015 Full-Size Utilities incorporate suspension design improvements for improved handling, decreased stopping distances, reduce body roll, etc. Many customers are very satisfied with the ride and handling, but some owners may feel the ride is not to their satisfaction. They may comment of a rough/harsh/stiff ride, or they may describe a vehicle vibration with a similar description. Typically, this condition is most noticeable between 35-55 mph on fairly smooth roads, when coming in contact with small/minor road imperfections/bumps, expansion joints, etc. The suspension will absorb larger bumps without complaints, but smaller/minor imperfections/bumps, which would normally be absorbed by the suspension, may not be absorbed as well as the owner would expect. Recommendation/Instructions Evaluate the vehicle using the vibration analyzer CH-51450-A (Pico Oscilloscope), driving the vehicle in 35-55 mph range on the same section of road for each stage of evaluation. Pico scope will normally show this ride condition as a Tire 2 or Unknown vibration (approximately 15-19 Hz) in response to small/minor road imperfections/bumps. The vibration analyzer should be used twice: 1st to determine the customer concern is a rough/harsh/stiff ride and 2nd after the repairs to verify the cause is repaired and to identify if other inputs / disturbances are present. The Hz and Mg readings should be documented using the Z95 rough/harsh/stiff ride / vibration chart below. Important: When using the vibration analyzer make sure to obtain readings after the vehicle has been driven at least 10-15 miles to warm up the tires and cycle the new shocks. After new shocks are installed they will need to be cycled before optimum ride is obtained, which is done during normal driving. [During evaluation, position the Pico accelerometer sensor to capture Both vertical and horizontal planes, for tri-axis sensor, ensure correct orientation for X, Y, and Z axis. Place the sensor on the seat track, console (avoid wireless charging mat), steering column, etc. If additional sensors are used, place at each vehicle corner to help narrow area of strongest input/disturbance.] Z95 MR Rough/Harsh/Stiff Ride / Vibration Worksheet Road Condition Small/minor road imperfections/bumps, expansion joints, etc. Speed Condition Occurs 35-55 MPH (55-90 KPH) Pico Scope Readings Before Any Repairs Sensor Mounted Vertical or Y plane at Drivers Seat Rail: Sensor Mounted Horizontal or Z plane at Drivers Seat Rail: MPH/KPH:__________ Hz:__________ m/g's:__________ MPH/KPH:__________ Hz:__________ m/g's:__________ Sensor Mounted Vertical or Y plane at _____________: Sensor Mounted Horizontal or Z plane at ___________: MPH/KPH:__________ Hz:__________ m/g's:__________ MPH/KPH:__________ Hz:__________ m/g's:__________ Pico Scope Readings After Repairs NOTE: Ensure vehicle is driven 10-15 miles to warm the tires and cycle the new shocks Sensor Mounted Vertical or Y plane at Drivers Seat Rail: Sensor Mounted Horizontal or Z plane at Drivers Seat Rail: MPH/KPH:__________ Hz:__________ m/g's:__________ MPH/KPH:__________ Hz:__________ m/g's:__________ Sensor Mounted Vertical or Y plane at _____________: Sensor Mounted Horizontal or Z plane at ___________: MPH/KPH:__________ Hz:__________ m/g's:__________ MPH/KPH:__________ Hz:__________ m/g's:__________ If a rough/harsh/stiff ride has been determined to be the customer’s concern, following evaluation using the Pico scope, then replace the complete front suspension shock with coil spring assemblies, and rear shocks with updated parts and reprogram the Suspension Control Module (K19) with updated calibrations available in TIS2WEB. (The calibration may be labeled "Real Time Damping.”) The updated part numbers listed below utilize various improvements to address the ride concern as described. Note: Vehicle alignment does not need to be adjusted as a result of the Z95 MR suspension component updates. Please note that this rough/harsh/stiff ride / vibration condition can be magnified by other inputs/disturbances which may be present, such as: Tire and wheel assemblies with excessive road force variation (RFV), propshaft balance / runout, and/or rear axle pitchline runout related issues. These updated suspension components will Not correct these other inputs/disturbances, which Must be addressed separately. If an issue in any of these other areas is found, it should be corrected Before returning the vehicle to the customer, See the latest version of PI1354 to work through other inputs/disturbances. Following Z95 MR-related updates, re-evaluate the vehicle to ensure no other inputs/disturbances are present. If other inputs/disturbances are present, review the additional diagnostic tips in this PI and correct the remaining conditions: – Tire and Wheel Assemblies – Propeller Shaft – Rear Drive Axle Additional Diagnostic Tips -Tire and Wheel Assemblies Ensure tire and wheel assemblies are not contributing to the issue. Keep in mind this rough ride issue will often show up as T2 in response to road input, (suspension reacting to road input, rather than absorbing it). If T1 is present, or any higher order, other than some T2 in direct-response to road input, expansion joints, etc. the tire and wheel assemblies must be investigated. There have been some cases of T2 tire issues, some high-speed RFV issues (primarily with the 22-inch Bridgestone tires), and some cases of tire/wheel assemblies showing acceptable RFV numbers, but with further investigation, have been found to have bent inboard rim flanges with hidden tire damage, visible inside when dismounted. The GSP9700 checks tire low-speed RFV only, in the radial plane only Object ID: 4204906Click here for detailed picture of the image. The GSP9700 is set to display T1 RFV. Higher order RFV, T2 & T3 can be displayed in the Assembly Data Plots Screen, as shown above. Depending on the level of GSP9700, the screen may be under ‘Data’ or ‘Runout Plots,’ then “Rim and Load Roller Runout Plots.” When checking tires on the GSP9700, if (radial) T2 is high or close to the (radial) T1 value, the tire should be replaced. As an example, if a tire and wheel assembly is measuring T1 at 10 lbs RFV, the tire would be considered good; however, if in displaying the higher orders, it is found that the tire and wheel assembly also has T2 at say 9 lbs RFV, the tire needs to be replaced. Refer to the latest version of PI1354 for latest procedures. Road Force Variation (RFV) Specification to Address Ride Concerns P-Metric Tires on Light Trucks, SUVs 15 lbs (6.8 kg) or Less NOTE: Arrange the tires on the vehicle in the following order: lowest RFV at LF, next RF, next LR, highest RR -Propeller Shaft Ensure the propshaft is not contributing to the issue. If any orders of P measured with significance on the Pico in vertical or horizontal planes – inspect the propshaft for dents or other damage. If no damage is present, check propshaft balance and runout, refer to the latest version of PI1354 for latest procedures. Remember to consider and inspect the transmission output shaft bushing for irregular wear. -Rear Drive Axle Ensure the rear drive axle is not contributing to the issue. Pitchline runout / gear set machining, followed by setup issues have been found to be contributors to vibration issues; not just whine noise concerns.Gear set machining issues in these axles seem to most often show up as P1 or higher order P related; with some showing as T1 or higher order of T related; all depending on gear set condition. If tire/wheel assemblies and propshaft have been ruled out / repaired, and P1, T1 or a higher order of P or T is still present in the vertical or horizontal plane – other than in direct-response to road input, the drive axle must be investigated Check for pitchline runout and setup issues, refer to the latest version of PI1354 for latest procedures. If drive axle repair is necessary, we have heard some reports that during repair, tooling chatter marks may be observed in the pinion race counterbores. This issue lends to the idea that the races may not be fully seated until some vehicle use is introduced into the axle. This issue would most often result in a noise concern, though severe loss of preload might produce a vibration. The races should be able to be fully seated during repair Parts Information Part Number Description Vehicle Model Spring Code Qty Front Note: Verify spring code RPOs, LH and RH for vehicle from the SPID label or IVH/GWM. Some vehicles by-design will have LH / RH spring codes which fall into different groupings / different part numbers for each side – they must be serviced in the same manner to best address this ride concern. For example: A truck with LH spring code of 6ZS, with RH spring code of 7ZR would use 23312158 for the Left side and 23312157 for the Right side. 23312152 Spring Asm-Frt Coil (w/ Shock) C157 06 6YR, 7YR, 6HD, 7HD 1 side 23312153 Spring Asm-Frt Coil (w/ Shock) C157 06 6ZC, 7ZC, 6HF, 7HF 1 side 23312154 Spring Asm-Frt Coil (w/ Shock) C159 06, K157 06 6ZD, 7ZD, 6H3, 7H3 1 side 23312155 Spring Asm-Frt Coil (w/ Shock) C159 06, K157 06 6ZN, 7ZN, 6H4, 7H4 1 side 23312156 Spring Asm-Frt Coil (w/ Shock) C159 06, K157 06 6ZP, 7ZP, 6JU, 7JU 1 side 23312157 Spring Asm-Frt Coil (w/ Shock) K159 06 6ZR, 7ZR, 6XF, 7XF 1 side 23312158 Spring Asm-Frt Coil (w/ Shock) K159 06 6ZS, 7ZS, 6XH, 7XH 1 side Rear 23267007 Absorber Asm-Rr Lvlg Shock ALL ALL 1 Side Warranty Information For vehicles repaired under warranty use: Labor Operation Description Labor Time 8080158* Replace Both Front Coil Spring/Shocks, Replace Both Rear Shocks and Reprogram Suspension Control Module Programming 3.5 hr** * This is an unique labor operation for bulletin use only.

  9. Checking in again hoping someone has gotten a resistor kit of sorts and some drop in shocks to bypass the factory flawed magneride system. I'm dreading spending $1200 (rock auto) for front and rears plus install on a two year old car.
  10. Fantastic. Thanks a lot Mark! Glad you got it all sorted out buddy! Now... if I could get someone to assist me in eliminating the magneride on my '15 Denali, I'd be grateful! ;)
  11. Has anyone been able to successfully install a standard shock on these things with a resistor kit? I'm dreading replacing all four of mine, but I cannot tolerate riding around town, feeling like a low rider with rigid suspension.
  12. Thanks Mark. I'm sure you saw the link I posted was reverse, that is the first thing I did notice. At least it's definitive now so others can save some serious cash!
  13. Anyone have a shock solution for front and back for Z95 and 6ZS/7ZS (front)? I am not looking forward to replacing all four magneride for $1200 + labor buying delco shocks from rockauto just to have them leak and fail again in a short amount of time. This thing is like riding on rocks with the driver's rear seized up completely.
  14. I did, but no specifics on width/pitch/length or anything. I should have measured and really taken a look at mine when I had it apart but was in a dang hurry because we were leaving on a 6-hour trip up to the time share and didn't want all three kids in the third row fighting. hahaha I have a feeling this would work https://www.ebay.com/itm/Flat-Ribbon-cable-40-Pin-0-5mm-Pitch-200mm-long-FFC-FPC-Reverse-Direct-1pc/112412362149?hash=item1a2c4c85a5:g:EMUAAOSw-K9ZHqwL
