DTC B1550-1A: Left Rollover Protection Deployment Control - Circuit resistance below threshold: 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. Install a new wiring harness as necessary.
- Using the Jaguar Land Rover approved diagnostic equipment, check datalogger signal - Deployment Control 6 Resistance (0x5B09). If the resistance is too low, disconnect and reconnect the left deployable roll-over protection unit connector, ensuring that the connector plunger is correctly engaged. Clear the DTCs and retest
- Disconnect the left deployable roll-over protection unit 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 left deployable roll-over protection unit circuit for short circuit between power and ground. Repair the wiring harness as necessary
- Using the Jaguar Land Rover approved diagnostic equipment, clear the DTCs and retest. If the fault persists, install a new left deployable roll-over protection unit
