DTC List - Transmission Control

NOTE:
- If a customer describes the symptoms for codes 3, 6, 11 or 17, yet the [D4] indicator light is not blinking, it will be necessary to recreate the symptom by test driving, and then checking the [D4] indicator light with the ignition still ON.
- If the [D4] indicator light displays codes 1, 2, 3, 7, 8, or 16, check first the No. 31, 35 and 22 fuse before electrical troubleshooting. If any of the fuses have blown, repair them and then recheck.
- If the [D4] indicator light displays codes other than those listed above or stays lit continuously, the PCM (Powertrain Control Module) is faulty.
- Sometimes the [D4] indicator light and the Malfunction Indicator Lamp (MIL)/Check Engine light may come on simultaneously. If so, check the PGM-FI system according to the number of blinks on the MIL, then reset the memory by removing the No. 15: ACG(s) fuse (7.5 A) in the under-dash fuse box for more than 10 seconds. Drive the vehicle for several minutes at speeds over 30 mph (50 Km/h), then recheck the MIL.

PGM-FI system
The PGM-FI system on this model is a sequential multiport fuel injection system.
- The [D4] indicator light may come on, indicating a system problem, when, in fact, there is a poor or intermittent electrical connection. First, check the electrical connections, clean or repair if necessary.
- If the electrical readings are not as specified when using the test harness, check the test harness connection before proceeding.
