Description
The PCM monitors various engine parameters to determine when an oil
change should be done. The PCM sends a message to the Instrument Panel Cluster
(IPC) when an oil change is needed. The PCM monitors the following to determine
when an oil change should occur:
| • | Engine coolant temperature |
Resetting The Oil Life Monitor
Important: If the Engine Oil Life Monitor is going to be reset due
to a PCM replacement, advise the customer. The customer has two options:
| • | Change the engine oil and filter. |
| • | Determine when the last engine oil change occurred. Monitor the
vehicle mileage and change the engine oil and filter at the next recommended
service interval. |
Important: Repair any TP sensor DTCs before proceeding with the reset procedure.
- Turn On the ignition leaving the engine OFF.
- Cycle the Accelerator Pedal from a closed throttle to a wide open
throttle (WOT) 3 times within 5 seconds. The Change Oil message flashes for
5 seconds when reset.
- Change the engine oil and the oil filter. Refer to
Engine Oil and Oil Filter Change
in Engine Mechanical.
