Circuit/System Verification

Ignition ON, observe the scan tool EBCM Wheel Speed Sensor parameters. The reading should be the same speed on all sensors when driving in a

straight line at a speed greater than 20 km/h (13 MPH).

Circuit/System Testing

1. Ignition ON, verify that DTC C0035, C0040, C0045, or C0050 is not present in the EBCM.

瀚慖f any listed DTC is present, refer to DTC C0035, C0040, C0045, or C0050 (See: C Code Charts/C0035) to diagnose that DTC prior to

this diagnostic.

2. Replace the K17 Electronic Brake Control Module (EBCM) and verify the DTC does not reset.

瀚慖f the DTC resets, replace the module that set the DTC.
