DTC B0013-12: Passenger Knee Bolster Deployment Control - Circuit short to battery: Action

NOTE: The passenger knee bolster 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 (for example using reasonable pressure), then this indicates that the connector is damaged. Repair the wiring harness as necessary

Refer to the electrical circuit diagrams and check the passenger knee bolster circuit for short circuit to power. Repair the wiring harness as necessary, clear the DTC and retest
If the fault persists, install a new passenger knee bolster as necessary
