Ignition ON, observe the scan tool Lateral Accelerometer Signal parameter. The reading should be 2.3-2.7 volts. 2. Ignition ON, observe the scan tool Yaw Rate Sensor parameter. The reading should be 2.3- 2.7 volts. Circuit/System Testing 1. Ignition OFF, disconnect the harness connector at the yaw rate/lateral accelerometer. 2. Test for less than 2 ohms of resistance between the ground circuit terminal 1 and ground. If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, test for 11.8 - 12.2 volts between the 12-volt reference circuit terminal 4 and ground. If less than the specified range, test the 12-volt reference circuit for a short to ground 4. Test for 5.5-7.0 volts between the CAN circuit terminal 3 and ground. If greater than the specified range, test the CAN circuit for a short to voltage. If the If less than the specified range, test the CAN circuit for a short to ground or an 5. Test for 5.5-7.0 volts between the CAN circuit terminal 2 and ground. If greater than the specified range, test the CAN circuit for a short to voltage. If the If less than the specified range, test the CAN circuit for a short to ground or an 6. Test for infinite ohm of resistance between the CAN circuit High, and Low terminals 2 and 3. If less than the specified range, test the CAN circuits for a shorted to each other. If the 7. If all circuits test normal, test or replace the yaw rate/lateral accelerometer sensor. Repair Procedures Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

DTC C0196 5A Yaw Rate Circuit Plausibility Failure Diagnostic Fault Information Circuit/System Description The lateral accelerometer and the yaw rate sensors are combined into one sensor external to the Conditions for Running the DTC The ignition switch is in the ON position. Conditions for Setting the DTC The yaw/lateral combination sensor fails an internal self test. Communication is lost between the EBCM and the yaw/lateral combination sensor. The correlation error between the yaw/lateral combination sensor and steering angle sensor. Action Taken When the DTC Sets One or more of the following actions may occur: The vehicle stability enhancement system (VSES) is disabled. Traction control system (TCS) is disabled. The TCS/VSES indicators turn ON. The driver information center (DIC) displays the Service Traction Control, and or Service Circuit Short to Ground Open/High Resistance Short to Voltage Signal Performance Yaw Rate Supply Voltage C0196 00 C0196 00 - - Yaw Rate CAN Bus High C0196 00 C0196 00 C0196 00 C0196 5A Yaw Rate CAN Bus Low C0196 00 C0196 00 C0196 00 C0196 5A Yaw Rate Ground Circuit - C0196 00 - -
