Some customers may comment on a Service Stability Message on the Drivers Information Center (DIC).
Diagnosis with a scan tool may indicate a DTC C0131, C0196, C0290 and/or C0292 is set.
There are two possible causes for this issue. Both possible causes are listed below:
• | An internal fault within the yaw rate sensor/lateral accelerometer, P/N 15189628, may be the first possible cause. |
• | The vehicle stability enhancement system (VSES) electronic brake traction control module (EBCM) calibration may be the second possible cause. |
• | DTC C0131 |
• | DTC C0196 |
• | DTC C0290 or C0292 (w/JL4) |
Follow the procedure below to inspect the part number on the yaw rate sensor/lateral accelerometer.
Important:
• OLD
yaw rate sensors/lateral accelerometers have a part number on the sensor bracket of P/N 15189628. • IMPROVED
yaw rate sensors/lateral accelerometers have a part number on the sensor bracket of P/N 15220053.
• | OLD yaw rate sensors/lateral accelerometers have a part number of P/N 15189628. |
• | IMPROVED yaw rate sensors/lateral accelerometers have a part number of P/N 15220053. |
Important: Replace the yaw rate sensor/lateral accelerometer, P/N 15189628, with new sensor, P/N 15220053
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten
Tighten the nuts to 10 N·m (89 lb in).
Important: The yaw rate reference reset procedure must be performed when replacing the yaw rate sensor/lateral accelerometer.
Important: Failure to reprogram the EBCM may result in a repeat repair.
