DTC List - Transmission Control

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




NOTE:
- If a customer describes the symptom for code P179O (3), yet the [D4] indicator light is not blinking, P17O6 (6) or PO725 (11), it will be necessary to recreate the symptom by test-driving, then recheck the DTC.
- Sometimes the [D4] indicator light and the Malfunction Indicator Lamp (MIL) may come on simultaneously. If so, repair the PGM-FI system according to the DTC, then reset the memory by removing the BACK Up RADIO fuse in the underdash fuse/relay box for more than 10 seconds. Drive the vehicle for several minutes at a speed over 30 mph (50 km/h), then recheck the DTC.
