DTC B0005-1A: Collapsible Steering Column 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:

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. Install anew wiring harness as necessary.
A shorting bar inside the connector (deployable device side) intentionally creates a short circuit until the wiring harness connector is installed AND the plunger is engaged.
Steering column collapse actuator 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 4 Resistance (0x5B07). If the resistance is too low, disconnect and reconnect the steering column collapse actuator connector, ensuring that the connector plunger is correctly engaged. Clear the DTCs and retest
Disconnect the steering column collapse actuator 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
Refer to the appropriate system wiring diagrams and check the steering column collapse actuator circuit for short circuit between power and ground
Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest. If the fault persists, install a new steering column collapse actuator
