Antilock Brakes / Traction Control Systems: Service Precautions

Safety Precautions And Fundamental Points Regarding Troubleshooting

- ABS is a vehicle safety system; appropriate knowledge is necessary to work on the system.

- Do not drive with the harness connector disconnected from the ABS control module -JI04-.

- In order to check complaints and perform DTC checking, DTC memory must be checked before starting work on the ABS or ABS/EDL system.

- Do not disconnect or re-connector harness connectors when the ignition is switched on.

- Do not loosen screws or bolts on the ABS hydraulic unit.

- ABS malfunctions are indicated by the ABS warning light coming on; certain malfunctions will be recognized only when exceeding 12 km1h (7.5 mph). A road test is therefore necessary.
