Engine Oil Life System

ENGINE OIL LIFE MONITOR
The oil life index parameter is an indication of the approximate percentage of useful engine oil life remaining since the last reset of the parameter. The oil life index is displayed as ### OIL LIFE LEFT. This figure is calculated by the PCM and sent to the IPC via the class 2 serial data line. When the oil life index parameter reaches 0% the CHANGE ENGINE OIL message is displayed.

The engine oil life index can be reset with a scan tool or with the reset function of the DIC. The DIC can reset engine oil life only to 100 percent. A scan tool can reset engine oil life in 10 percent increments.


RESET PROCEDURE
In order to reset the oil life index after an oil change, do the following.
- With ignition switch at RUN, Engine OFF:
1. Display the % OIL LIFE LEFT parameter on the DIC by repeatedly pressing the SKIP/INFO button.
2. Press and hold the NO/INFO RESET button until "100" is displayed.

Note: Reset the oil life index after each oil change even if the CHANGE ENGINE OIL message did not come on.
