Engine Off Timer



Engine Off Timer

Description
The engine off timer monitors compares the real time clock data supplied by the instrument pack with it s own internal counter.

If the two differ by more than 2 seconds for longer than a predefined time then a failure is registered. If the fault occurs on 2 drive cycles then the MIL will illuminate.





If the above table does not include details of the following enabling conditions: - IAT, ECT, vehicle speed range, and time after engine start-up then the state of these parameters has no influence upon the execution of the monitor.
