ON-BOARD DIAGNOSTICS
This diagnostic procedure is used only on Probe vehicles equipped with an anti-lock brake system (ABS). The Quick Test procedure should be used only when diagnosing ABS symptoms.

On-Board Diagnostics is divided into two specialized tests: "Key ON, Engine Running Test (KOER)" and "Continuous Test." Prior to performing either test, an inspection of the anti-lock brake warning indicator is required to verify that indeed a fault has been detected by the anti-lock brake control module or if the system is operating normally. When the ABS system is operating normally, the anti-lock brake warning indicator will illuminate during key ON, engine off (KOER) and go off after the engine has started. If the anti-lock brake warning indicator stays on after the engine starts, this indicates a present failure. The logic circuit could keep the anti-lock brake warning indicator ON after the engine starts for up to 60 seconds. Failure codes are stored in the anti-lock brake control module until they are erased.

DIAGNOSTIC CODES, RETRIEVING
Anti-lock brake system (ABS) diagnostic trouble codes may be retrieved using the following methods:
- Identifying voltage fluctuations of an analog voltmeter.
- Identifying flashes of the anti-lock brake warning indicator.
- Reading a diagnostic trouble code (DTC) from a New Generation STAR (NGS) Tester 007-00500.

The test connector available for obtaining ABS diagnostic trouble codes is the data link connector (DLC) located near the battery.

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. The diagnostic trouble codes may indicate different failures and not completing the Quick Test procedure may result in code identification error.
