B0020-13: Left Side Airbag 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. Repair the wiring harness as necessary
Left side airbag (seat) 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 21 Resistance (0x5B3B). Refer to the electrical circuit diagrams and check the left side airbag (seat) circuit for open circuit, high resistance
If a harness fault is confirmed, the harness may be repaired with the designated overlay harness repair kit. For additional information, Refer to: WIRING HARNESS OVERLAY
Disconnect the left side airbag (seat) 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
Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest
