DTC 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 total resistance of the airbag circuit (including harness, connectors, airbag) should be 1.70 ohms to 3.6 ohms between -40 deg C to +85 deg C
When the airbag connector is DISCONNECTED if the locking plunger can move to the locked position easily (reasonable pressure) the connector is damaged

Visually inspect the left side airbag connector, the locking plunger should be flush with the housing. If not, push the locking plunger in. Clear the Diagnostic Trouble Code(s) and retest. Refer to AIRBAG SUPPLEMENTARY RESTRAINT SYSTEM (G2424832) and perform appropriate pinpoint test
Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signal - Deployment Control 5 Resistance (0x5B08) in LHD vehicles or Deployment Control 7 Resistance (0x5B0A) in RHD vehicles. If the resistance is too high, disconnect and reconnect the left side airbag connector, making sure that the connector plunger is correctly engaged. Clear the Diagnostic Trouble Code(s) and retest
If problem still persists, disconnect and reconnect all connectors. Also test connectors (see above note). Clear the Diagnostic Trouble Code(s) and retest
Refer to the electrical circuit diagrams and check the left side airbag (seat) circuit for open circuit, high resistance. Repair the circuit as necessary, clear the DTC and retest
If the fault persists, install a new left side airbag as necessary
