DTC B1211-13: Driver Seatbelt Retractor Pretensioner Deployment Control - Circuit open: Action

WARNING: Do not measure the resistance of a deployable device circuit using any other method than that described below. Failure to follow this instruction may result in personal injury.

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. Repair the wiring harness as necessary
The resistance specification of the driver seatbelt retractor and pretensioner is 1.70 Ω to 3.28 Ω at a temperature between -40°C and 85°C

Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signal - Deployment Control 13 Resistance (0x5B10). Refer to the electrical circuit diagrams and check the driver seatbelt retractor and pretensioner circuit for open circuit, high resistance. Repair the wiring harness as necessary
Disconnect the driver seatbelt retractor and pretensioner connector and apply light pressure to the connector plunger. If the plunger moves to the engaged position the connector is damaged. Repair the wiring harness as necessary
