When a system malfunction is detected, the engine's electronic control unit diagnoses and stores the error

In addition, the check engine warning light in the instrument cluster comes on or flashes to inform the driver

The engine ECM will also store fault diagnostic codes (DTCs).

Diagnostic codes can be accessed using a portable tester.

The time required to clear the control unit of diagnostic codes (DTC) by disconnecting the battery has been increased from 10 seconds (on previous models) to 1 minute.
