Tech Tips
-
*1: The ECM will start measuring the time elapsed after the malfunction is detected at the same time the MIL starts blinking. If an idle signal is input or engine speed 200 rpm or less after the total ignition-on time has reached 50 hours have elapsed and the MIL is still blinking, engine output will be limited to 75%.
-
*2: If an idle signal is input or engine speed 200 rpm or less after the MIL stops blinking, the engine output limiting control will stop. After the ECM determines that the vehicle has returned to normal condition for 3 successive trips, the MIL will stop blinking. If the MIL is blinking, the DTC cannot be cleared using the tester.
