DTC B1551-13: Right Rollover Protection Deployment Control - Circuit open: Action

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2019 Land Rover Range Rover Evoque, 2018 Land Rover Range Rover Evoque, 2017 Land Rover Range Rover Evoque, 2016 Land Rover Range Rover Evoque, and 2015 Land Rover Range Rover Evoque. However, it is still accessible from the selected car via links, so may be relevant.

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 8 Resistance (0x5B0B). Refer to the appropriate SYSTEM WIRING DIAGRAMS and check the right deployable roll-over protection unit circuit for open circuit, high resistance. Repair the wiring harness or install a new right deployable roll-over protection unit as necessary
Disconnect the right 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
