Initial Inspection and Diagnostic Overview

Inspection and Verification
1 Verify the customer concern.
2 Confirm if the Anti-Lock Brake System (ABS) warning light was illuminated, or still is.

NOTE:
An intermittent fault may allow the warning light to go off. This does not necessarily mean the fault is not present. Some warnings will appear to clear when the ignition is cycled. This is often because the warning has flagged as a result of one of the vehicle's on-board diagnostic routines having run to detect the fault. If the same routine is not run when the ignition is switched ON, the warning will not reflag until the routine does run.
3 Visually inspect for obvious signs of damage and system integrity.










4 If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
5 If the cause is not visually evident use the Jaguar approved diagnostic system or a scan tool to retrieve the Diagnostic Trouble Codes (DTCs) before proceeding to the DTC Index.
