DTC B0073-13: Second Row Left Seatbelt Pretensioner Deployment Control - Circuit open: Action

WARNING: Do not measure the resistance of a deployable device using any other method than that described below.

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.
Rear left seatbelt retractor pretensioner resistance specification is 1.70 ohms to 3.28 ohms at -40°C to 85°C.

Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signal - Deployment Control 11 Resistance (0x5B0E). Refer to the appropriate system wiring diagrams and check the rear left seatbelt retractor pretensioner circuit for open circuit, high resistance
Disconnect the rear left seatbelt retractor 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 rear left seatbelt retractor pretensioner
