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
- Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signal - Deployment Control 24 Resistance (0x5B3E). If the resistance is too low, disconnect and reconnect the third row right seatbelt retractor pretensioner connector, making sure that the connector plunger is correctly engaged. Clear the Diagnostic Trouble Code(s) and retest
- Refer to the electrical circuit diagrams and check the third row right seatbelt retractor pretensioner circuit for short circuit between power and ground
- If a wiring fault is detected, repair the wiring as required
- If no wiring harness fault exists, using the Jaguar Land Rover approved diagnostic equipment, clear the Diagnostic Trouble Code(s) and retest. If the fault persists, install a new third row right seatbelt retractor pretensioner as necessary
