Auto Stop/Start System Inhibits

WARNING: This page is about a different variant/trim than selected.

The inhibit conditions listed below will not set a DTC  but will set flags which can be viewed using the Jaguar Land Rover approved diagnostic equipment - Datalogger/Powertrain Control Module (PCM). Normal Auto Stop/Start system operation will resume when an inhibit condition is no longer present, but the battery related inhibits may persist for some time.

NOTE:
  • Performing a DTC  clear on a petrol (gas) engine vehicle will inhibit the auto stop/start system.
  • Do not reset the Battery Monitoring Sensor (BMS) to rectify battery condition inhibits. This may temporarily restore the auto stop/start system operation but will lead to a recurrence of the fault.
