vehicle’s OBD II Monitors. Monitors are tests to verify operation of emission

 

related systems or components and detect out-of-range values. Vehicle may

 

have to be operated under certain driving conditions to initiate a monitor. If

 

vehicle loses electrical power or codes are erased, monitors may be cleared.

 

This function can be performed with key ON — engine OFF (KOEO) or key ON

 

— engine Running (KOER).
