ECO System Inhibits

The inhibit conditions listed below will not set Diagnostic Trouble Codes (DTCs) but will set flags which can be viewed using the manufacturer approved diagnostic system - Datalogger/Engine Control Module (ECM). Normal ECO 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 System (BMS) to rectify battery condition inhibits. This may temporarily restore ECO system operation but will lead to a recurrence of the fault.
