DTC B0078-1A: Third Row Right Seatbelt Pretensioner Deployment Control - Circuit resistance below threshold: Action

WARNING: Do not measure the resistance of a deployable device using any other method than that described below
NOTE:
  • A shorting bar inside the connector (deployable device side) intentionally creates a short circuit until the wiring harness connector is installed AND the connector plunger is engaged
  • The total resistance of the airbag circuit (including harness, connectors, airbag) should be 1.70 ohms to 3.6 ohms between -40 deg C to +85 deg C
