DTC B0020-1A: Left Side Airbag 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
Airbag resistance should be 1.70 ohms to 2.30 ohms between -40 deg C to +85 deg C

Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signal - Deployment Control 5 Resistance (0x5B08). If the resistance is too low, disconnect and reconnect the left side airbag connector, making sure that the connector plunger is correctly engaged. Clear the DTCs and retest
Refer to the electrical circuit diagrams and check the left side airbag circuit for short circuit between power and ground. Clear the DTCs and retest. If the fault persists, repair the wiring harness as necessary
If no wiring harness fault exists, using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest
