Oil Change Reminder Lamp: Description and Operation

SERVICE REMINDER DISPLAY

- The SERVICE REMINDER section of the DIC Display shows how many miles remain until service is needed. When the RESET button is pressed twice, a type of service and the number of miles remaining until it is needed will be displayed. Each time the RESET button is pressed, another type of service and the miles remaining for it will be displayed.

- With the Ignition Switch in RUN, BULB TEST, or START, voltage is applied from the ECM Fuse through the PNK/BLK wire to the Electronic Control Module (ECM). As the car moves, the Speed Sensor sends electrical pulses to the ECM. The ECM sends a signal to the speed signal input of the DIC Module. The DIC Module converts these pulses to miles. The Module subtracts the miles travelled from the distance remaining for each item on the SERVICE REMINDER

- When the miles remaining for a service approaches zero, that service will be displayed on the DIC Display. All four types of service can be shown at the same time.

SERVICE REMINDER RESET
- The miles remaining for a certain type of service can be decreased. By holding the RESET button, the miles remaining will decrease in steps of 500 miles every five seconds.

- In the first step, the miles will decrease to a multiple of 500. For example, 2880 miles will decrease to 2500 miles.

- If the RESET button is held in and miles remaining reach zero, the DIC Display will show the service interval for the service selected.
The table below shows the service intervals.

SERVICE INTERVALS
Change Oil 7,500 miles
Oil Filter Change 7,500 miles
Next Filter Change 15,000 miles
Rotate Tires 7,500 miles
Next Tire Rotation 15,000 miles
Tune Up 30,000 miles

- If the RESET button is still held down, the miles will decrease in steps of 500 miles from the service interval.

- When the RESET button is released, the mile display shown will be the new distance until the next service should be performed.

- When a service distance reaches zero, the Service Reminder item will be displayed.

- If the service interval is reset within ten miles, the display will go out immediately.
If more than ten miles passes before the service interval is reset, the item will remain displayed for another ten miles after being reset before going out.
