Transaxle Fluid Life Interval Programming (4.0L)
- Transaxle fluid 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.
- Transaxle fluid life interval is calculated by the Powertrain Control Module (PCM). The PCM uses many engine parameters to determine the percentage of transaxle fluid life interval remaining before fluid should be changed.
- When PCM determines transaxle fluid should be changed, a signal is sent to the instrument cluster and warning light is displayed. 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, transaxle fluid life interval must be reprogrammed or reset.
- To reprogram or reset transaxle fluid life interval to original interval set in the PCM, connect scan tool to Data Link Connector (DLC). Using scan tool manufacturer's instructions and reprogram or reset transaxle fluid life interval back to the closest original interval index that was recorded on original PCM.
