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

2. Locate area shown above transmission and
transfer case, if equipped.
3. Ensure the area is free of any debris by cleaning

7. Inspect the area to ensure coverage of the area is
complete and even.
8. Remove all material used to protect from

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.

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.
