On-Board Diagnostics

The anti-lock brake system has self-diagnostic capabilities. However, the anti-lock brake control module as received from manufacturing is equipped with a stored Diagnostic Trouble Code (DTC) 61. This will affect the service procedure.

The DTCs can be retrieved from the anti-lock brake control module in the following manner.

1. Connect Super STAR II Tester to anti-lock brake test connector located in luggage compartment.
2. Place tester in slow mode.
3. Turn on Super STAR II Tester and latch button down in TEST position.
4. Turn ignition switch to RUN position.

NOTE: Ensure that all DTCs are written down.

NOTE: If the BRAKE warning indicator is ON or intermittently comes on, refer to the warning indicator chart.

5. Read first DTC output. After approximately 15 seconds the next DTC will be output. Leave button latched until all DTCs are output.

The diagnostic procedure should be as follows providing that the Check ANTI-LOCK BRAKE indicator stays on all the time or flashes intermittently.

NOTE: If there are more DTCs stored in the anti-lock brake control module's memory, no code will be erased until all DTCs have been output by the Super STAR II Tester, all malfunctions have been serviced and the vehicle is driven above 40 km/h (25 mph). This means that if a 20's DTC originally existed and was serviced, it can be ignored when running the on board diagnostic the second time.

1. If the first DTC output is in the 20's and no other DTC is output, service the indicated component. No other DTCs can be output if a 20's DTC exists. After servicing the indicated 20's DTC, repeat the procedure for retrieving DTCs.
2. If DTC 61 is output with any other DTC, ignore the DTC 61 and service the other indicated malfunctions. If after correcting all other indicated malfunctions, the Check ANTI-LOCK BRAKE indicator is still on, service the 61 DTC.
3. If a DTC 61 is output and no other DTCs are output, service DTC 61.
4. If no DTC, or only a DTC 10 is output, use the Anti-Lock Quick Check Sheet since some possibilities are not recognized and retained in the anti-lock brake control module memory. Pinout Values and Diagnostic Parameters
