Circuit/System Verification

1. Is DTC U0123, U0124, or U0126 also set?

• If DTC U0123, U0124, or U0126 is set, refer to appropriate DTC.

2. Verify yaw rate sensor is correctly installed.

• If yaw rate sensor is not correctly installed, correct installation of yaw rate sensor and using a scan tool perform yaw rate sensor calibration.

• If yaw rate sensor is correctly installed, replace EBCM.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
