Engine Oil Life System

ENGINE OIL LIFE MONITOR RESET PROCEDURE
The Fluid Life Indexes are calculated by the PCM. The PCM uses many engine parameters to determine the percentage of fluid life remaining for the engine oil and transaxle fluid. The fluid life indexes are stored in the nonvolatile memory area of the PCM's EEPROM. When the PCM is disconnected from power these indexes will remain in memory.

The engine oil life index can be reset using the following methods:
^ Pushing the accelerator pedal to the floor three times within 5 seconds.
^ Reset flintion on the DIC.
^ Scan tool.

The DIC and accelerator methods will only reset the life indexes to 100 percent. The scan tool will reset life indexes in 10 percent increments.
