Idle Speed Control

Idle Speed Control

Description
If all the entry conditions are satisfied, then the monitor will start execution.

If the actual engine speed more than 100 rpm lower than the target engine speed then a counter is started and once this exceeds the failure time limit a failure judgement is made for idle speed lower than expected.

If the actual engine speed is greater than 200 rpm higher than the target engine speed then a counter is started and once this exceeds the failure time limit a failure judgement is made for idle speed higher than expected.





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.
