Inspection And Verification
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED BEFORE REPAIRING OR REPLACING ANY AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS. TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT ONE MINUTE. FAILURE TO FOLLOW THIS INSTRUCTION MAY RESULT IN PERSONAL INJURY.
CAUTION:
Diagnosis by substitution from a donor vehicle is NOT
acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTE:
Given the legal implications of a restraints system failure, harness repairs to Air Bag module circuits are not acceptable. Where the text refers to "REPAIR the circuit", this will normally mean the replacement of a harness.
- Verify the customer concern.
- Visually inspect for obvious signs of damage and system integrity.
Visual Inspection
ELECTRICAL - Battery condition, state of charge
- Make sure all electrical connector(s) are engaged correctly on the air bag circuits
- Wiring harness
- Air bag module(s)
- Make sure the Restraints control module is correctly installed
- Fuse(s)
- Sensor(s)
- Pretensioner(s)
- Warning lamp bulb(s)
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the relevant DTC Index.
Given the complexity of the system and the potential for damage/injury, the preferred method of diagnosis is via the Jaguar approved diagnostic system.
If the Jaguar approved diagnostic system is not available, use a scan tool to extract DTCs and refer to the relevant DTC Index.
