5. If the cause is not visually evident, connect the diagnostic tool to the data link connector and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
- check that the program card is correctly installed.
- check the connections to the vehicle.
- check the ignition switch position.
6. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating information.

NOTE: If equipped with stability assist, the vehicle must be at a complete standstill when carrying out the self-test. Any movement of the vehicle during the self-test may result in false DTCs being set.

7. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- CAN, ISO or UBP circuit fault; all electronic control units no response/not equipped, refer to Information Bus.
- No response/not equipped for the ABS module, Go To Pinpoint Test H. H: No Communication With the ABS Module
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the ABS module.
8. If the DTCs retrieved are related to the concern, go to the Anti-Lock Brake System (ABS) Module Diagnostic Trouble Code (DTC) Index to continue diagnostics. Scan Tool Testing and Procedures
9. If no DTCs related to the concern are retrieved, GO to Symptom Chart to continue diagnostics. Symptom Related Diagnostic Procedures
