1998 Chevrolet Camaro SS, 2D Coupe, StandardSECTION Engine Oil Life Interval Programming (4.0L)
- Engine oil life interval programming must be performed if any of the following have been done:
- Battery voltage was disconnected from PCM before ignition switch was placed in LOCK position for a minimum of 30 seconds.
- EEPROM was reprogrammed.
- PCM was replaced.
- Engine oil life interval is calculated by the Powertrain Control Module (PCM). The PCM uses many engine parameters to determine the percentage of engine oil life remaining before engine oil should be changed.
- Engine oil life interval may be read by the operator by depressing ENG button on Driver Information Center (DIC). The DIC is located above the climate controls at center of instrument panel. Engine oil life interval will be displayed as a percentage when DIC indicates OIL LIFE.
- If battery voltage was disconnected from PCM before ignition switch was placed in LOCK position for a minimum of 30 seconds, or PCM was replaced, engine oil life interval must be reprogrammed or reset. Engine oil life interval may be programmed or reset by using a scan tool or the DIC.NOTE: Scan tool may reset engine oil life interval index in 10 percent intervals. The DIC can only reprogram or reset engine oil life interval to 100 percent.
- If using scan tool to reprogram or reset engine oil life interval, use scan tool manufacturer's instructions and reprogram or reset engine oil life interval back to the closest original interval index that was recorded on original PCM. Scan tool may reset engine oil life interval index in 10 percent intervals.
- If using DIC to reprogram or reset engine oil life interval, ensure ignition is on. Depress ENG button on DIC until displays OIL LIFE percentage. Depress and hold RESET button on DIC for 5 seconds. The word RESET will be displayed and then OIL LIFE 100 percent will be displayed. Release all buttons. The DIC can only reprogram or reset engine oil life interval to 100 percent.
