DTC B0004-2B: Driver Knee Bolster Deployment Control - Signal cross coupled: Action

NOTE: The deployable device 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.

Refer to the appropriate SYSTEM WIRING DIAGRAMS and check the driver lower airbag circuit for short circuit to another restraints circuit. Repair the wiring harness as necessary. Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest. If the fault persists, install a new driver lower airbag
