DTC List - Transmission Control Systems

(DTC)*: The DTC in parentheses is the code the [D4] indicator light indicates when the service check connector is connected to the special tool (SCS service Connector).

(37)**: Code 37 is caused by a faulty SEAF or SEFA wire between the TCM and the ECM, or a faulty ECM. The [D4] indicator light cannot indicate code 37 even though 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 below.

NOTE:
- If a customer describes the symptom for code P1706 (6) or P0725 (11), it will be necessary to recreate the symptom by test driving, then rechecking the DTC.
- Check the Malfunction Indicator Lamp (MIL) and repair the PGM-FI control system before repairing the A/T control system under conditions:
- When the MIL and the [D4] indicator light come on simultaneously.
- When the [D4] indicator light does not indicate the DTC with the ignition switch turned ON, even though the [D4] indicator light has been reported on and the service check connector is connector with the special tool.
- After repairing the PGM-FI control system, disconnect the BACK UP fuse (7.5 A) in the under-hood fuse/relay box for more than 10 seconds to reset the TCM memory. Drive the vehicle for several minutes at a speed over 30 mph (50 km/h), then recheck the DTC.
- Disconnecting the BACK UP 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.
