DTC B0073-1A: Second Row Left Seatbelt Pretensioner Deployment Control - Circuit resistance below threshold: Action
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2017 Jaguar XJR, 2017 Jaguar XJ, 2016 Jaguar XJR, 2016 Jaguar XJ, and 2015 Jaguar XJR. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Do not measure the resistance of a deployable device using any other method than that described below.
NOTE:
The airbag connector has a locking plunger (orange tab) which should only fully lock when the two connectors are securely mated, male to female. If the plunger can move to the locked position easily when not mated (ie: using reasonable pressure), then this indicates that the connector is damaged. Install a new wiring harness as necessary.
- Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signal - Deployment Control 11 Resistance (0x5B0E). If the resistance is too low, disconnect and reconnect the rear left seatbelt retractor pretensioner connector, ensuring that the connector plunger is correctly engaged. Clear the DTCs and retest
- Disconnect the rear left seatbelt retractor pretensioner connector and apply light pressure to the connector plunger. If the plunger moves to the engaged position the connector is damaged. Install a new wiring harness as necessary
- Refer to the applicable System Wiring Diagram(s) and check the rear left seatbelt retractor pretensioner circuit for short circuit between power and ground
- Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest
