Finished build....Scanner says lost communication with the multi axis acceleration sensor module.
Changing the yaw sensor didn't fix the issue.
But have Service Stabilitrak, service airbag, service park assist is displayed on dic..... windows, door locks, trunk release, seat belt & turn signal chim, and radio sound all don't work. Visually the radio and GPS work just no sound.

What codes do you have? What kind of build? Did you pull the engine? If so triple check grounds.

Complete rebuild. Whipple, tsp stage 2 blower cam, ported heads, 102tb, other supporting mods. All grounds have been checked and rechecked. Yaw sensor replaced but still get no communication with sensor.

Hello I’ve been cruising the Internet for days and days trying to find somebody that’s experience the same problem that I’m having with my 2011 Camaro and it appears you’re the guy, but I see you never posted a solution did you ever find a way to repair those codes? I just bought this car after it had a heater core dash removal done and all of these codes happened after the heater core job! I have checked all the grounds done continuity tested,check the green line bus data bridge. Still no joy exactly the same codes exactly the same symptoms as you experience. Please let me know if you ever did find a solution I would appreciate it greatly. Thanks

You have to Perform the Vehicle Yaw Sensor Learn with a scanner after replacement

Thanks for your advise.the yaw rate sensor was not my problem. I have GM software, and J2534 passthru programmer and yaw rate relearn was not needed. I did locate my problem, and since I bought it that way on the cheap, and didn’t replace the heater core or remove the dash, I don’t feel embarrassed to tell anyone else what it was. There are two big plugs above the kick panels on each side of the car. Both plugs have a lever that has to be pulled back and it will unplug the harnesses on both side which has to be done when removing the dash. On the drivers side it’s called Connecter X207. The release level was cracked by whoever did the job and they just forced the harness back together without actually fastening the lever back in place properly which caused the plug not seat properly. I just completely removed the broken lever and made sure the plug bottomed out and Zipped tied it and all is well. I hope any else that has this issue can benefit from my experience.
