DTC B0078-13: Third Row Right Seatbelt Pretensioner Deployment Control - Circuit open: Action
WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport, 2017 Land Rover Discovery Sport, 2016 Land Rover Discovery Sport, and 2015 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Do not measure the resistance of a deployable device using any other method than that described below.
NOTE:
- The deployable device 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.
- Third row right seatbelt pretensioner resistance specification should be greater than 1.70 ohms and less than 3.28 ohms at -40°C to 85°C.
- Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signal - Deployment Control 16 Resistance (0x5B36). Refer to the appropriate system wiring diagram and check the third row right seatbelt pretensioner circuit for open circuit, high resistance
- Disconnect the third row right seatbelt pretensioner connector and apply light pressure to the connector plunger. If the plunger moves to the engaged position the connector is damaged. Install a new wiring harness as necessary
- Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest. If the fault persists, install a new third row right seatbelt pretensioner
