Air Bag System - SRS Overlay Harness Availability
No.: LA501-020
Issue: 1
Date: June 12, 2006
SECTION: 501-20B
Supplemental Restraint System Overlay Harnesses
AFFECTED VEHICLE RANGE:
Land Rover LR3 (LA)
VIN: 5A000360 onwards
CONDITION SUMMARY:
OVERLAY HARNESS REPAIRS TO SUPPLEMENTAL RESTRAINT SYSTEM (SRS) WIRING
NOTE:
Service repair harnesses are now available to repair sections of the fascia/body SRS wiring harness without replacement of the complete harness.
The Worldwide Diagnostic System (WDS) may display Diagnostic Trouble Codes (DTC) from the Restraints Control Module (RCM) indicating an SRS
wiring fault for one or more of the following reasons:
^
SRS wiring harness open circuit
^
SRS wiring harness short circuit
^
Air bag deployment during a vehicle collision which causes heat damage to an air bag connector.
Cause:
SRS wiring harness damage or open circuit/short circuit condition.
Action:
In the event a DTC from the RCM indicates an SRS wiring fault, refer to the Workshop Manual Service Procedure detailed in this bulletin to identify
and replace the problem harness section with the appropriate overlay repair harness.
CAUTION:
The firing circuit wiring between the air bags and RCM must not be repaired under any circumstances and must be replaced using the overlay
harnesses described below.
If an air bag has been deployed, the wiring harness that connects directly to the air bag MUST be replaced at the same time as the deployed air bag.
If a seat belt pretensioner has been deployed, replace this component only.
In case of the driver's air bag deployment, the "clock-spring" spiral connector MUST be replaced at the same time as the deployed air bag, but it is
not necessary to replace the harness from the clock-spring to the fascia/body harness connector.
CAUTION:
Where an air bag has deployed, the SRS overlay harness sections associated to the deployed air bag MUST be installed.
