DTC B0020-2B: Left Side Airbag Deployment Control - Signal cross coupled: Action

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 (i.e.: using reasonable pressure), then this indicates that the connector is damaged. Repair the wiring harness as necessary

Refer to the electrical circuit diagrams and inspect the left side airbag (seat) circuit for short circuit to another restraints circuit
