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.
- Refer to the applicable System Wiring Diagram(s) and and check the rear left seatbelt retractor pretensioner circuit for short circuit to power
