Symptom Troubleshooting Index

(DTC)*: The DTCs in the parentheses are the number of the [D4] indicator light blinks when the service check connector is connected with the special tool.




If the self-diagnostic [D4] indicator light does not blink, perform an inspection according to the table above.

NOTE:
- If a customer describes the symptom for code P1706 (6) or PO715 (15), it will be necessary to recreate the symptom by test-driving, then recheck the DTC.
- The [D4] indicator light and the Malfunction Indicator Lamp (MIL) may come on simultaneously.
- Check the PGM-FI system according to the DTC, then reset the memory by removing the CLOCK, RADIO fuse in the under-hood fuse/relay box for more than 10 seconds.
- Drive the car for several minutes at a speed over 30 mph (50 km/h), then recheck the DTC.
- Disconnecting the CLOCK, RADIO fuse also cancels the radio anti-theft code, preset stations and the clock setting.
- Get the customer's code number, and make note of the radio presets before removing the fuse so you can reset them.
