Retrieving/Clearing Diagnostic Trouble Codes (DTC's)

Anti-Lock Brake System (ABS) diagnostic trouble codes may be retrieved using the following methods:

- Identifying voltage fluctuations with an analog voltmeter.
- Identifying flashes of the anti-lock brake warning indicator.
- Reading a digital or audible code from a Rotunda Super STAR II Tester 007-0041B using Rotunda Super MECS Adapter 007-00052.

The test connector available for obtaining diagnostic trouble codes is the Data Link Connector, located near the battery.

The diagnostic trouble codes may indicate different failures, and parting from the Quick Test procedure may result in code identification error. Therefore, it is recommended that the Quick Test procedure be followed to its entirety. Anti-lock brake warning indicator mode inspection and ABS diagnostic trouble code retrieval are covered in the Quick Test. Quick Check/Symptom Tests
