Attention:

This Bulletin also applies to any of the above models that may be Export vehicles.

Condition
Some customers may comment on a Service Stabilitrak message displayed on the Driver Information Center (DIC).
During diagnosis, a technician may find DTC C0196-5A set in the EBCM.

Cause
C0196-5A is related to YAW sensor plausibility. Engineering has determined that stone impacts to the underside of the transmission tunnel, right below the
SDM, may cause the YAW/Lat sensor located in the SDM to send signal spikes related to the resonant frequencies of the sheet metal; 12-14 kHz range. If the
YAW/Lat signals don’t line up with vehicle speed and steering angle sensor data, the EBCM will set C0196-5A, plausibility fault. Sometimes the SDM will set
C0196-00, invalid yaw rate data fault, if the stone impingement crosses the internal sensor fault threshold while will in turn cause the EBCM to set a C0452-71.

Correction
If you encounter a vehicle with the above concern, follow diagnostic procedures in SI relative to the DTCs that are present.
After completing necessary repairs to address the DTCs, perform the following procedure. Applying vibration deadening material to the underside of the
transmission tunnel is intended to dampen the frequency of stone impacts to prevent a repeat occurrence.
1.

Raise and support vehicle. Refer to Lifting and Jacking the Vehicle in SI.

1

2.

Locate area shown above transmission and transfer case, if equipped.

3.

Ensure the area is free of any debris by cleaning the area with wax and grease remover or equivalent. Ensure area is dry.

4.

Mark the transmission tunnel as noted.

5.

Wrap and tape off transmission, transfer case, propeller shaft, cables, wiring, exhaust, etc.to protect from overspray as illustrated above.
Note: It is also recommended to protect/tape off the surrounding areas to improve the finished appearance.

6.

Apply vibration deadening/damping material specified to the marked area following manufacturer’s guidelines.
Note: It may be necessary to apply the material in 2-3 coats to obtain desired thickness.

7.

Inspect the area to ensure coverage of the area is complete and even.

8.

Remove all material used to protect from overspray.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
