Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT WIRING HARNESS BETWEEN ABS HU/CM AND DLC-2 FOR CONTINUITY AND SHORTS • Perform DTC inspection. • Is error message displayed regarding communication between ABS HU/CM and WDS or equivalent? | Yes | If the communication error message is displayed even after inspecting according to procedures displayed in the WDS or equivalent, go to Step 4.
No | Go to next step.
