1. VISUALLY INSPECT COMPONENTS FOR DAMAGE AND CORRECT INSTALLATION
Visually inspect the Yaw Rate/Acceleration Sensor for damage and correct installation.
Are there any visible Sensor concerns?
Yes >> Correct the sensor concerns as necessary Perform ABS VERIFICATION TEST. ABS Verification Test
No >> Go to 2

2. MONITOR THE CAB WITH THE DRBIII





With the DRBIII, erase DTCs. Start the engine. With an assistant to drive, use the DRBIII to monitor the CAB module DTCs while performing road test.
Is the Yaw Rate/Acceleration Sensor DTC set?
Yes >> Replace the Yaw Rate/Acceleration Sensor. Perform ABS VERIFICATION TEST. ABS Verification Test
No >> Inspect and repair the related wiring harness for a possible intermittent condition. Perform ABS VERIFICATION TEST. ABS Verification Test
