Circuit/System Verification

Ignition ON, observe the scan tool EBCM Wheel Speed Sensor parameters. The parameters displayed should be within 1.6 km/h (1 MPH) 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 K17 EBCM.

瀚慖f any listed DTC is present, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code

Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).

2. Replace the K19 Suspension Control Module and verify the DTC does not reset.

瀚慖f the DTC resets, replace the K17 electronic brake control module (EBCM).

Repair Instructions

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