Checking the Diagnostic Trouble Code (DTC) with the Service Check Connector and Special Tool

When the TCM senses an abnormality in the input or output systems, the D4 indicator light in the gauge assembly will blink.

When the Service Check Connector (located under the dash on the passenger side) is connected with the special tool as shown, the D4 indicator light will indicate (blink) the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON (II).

when the D4 indicator light has been reported on, connect the Service Check Connector with the special tool. [someone else linked in here how to read this using a paperclip]

Then turn ON (II) the ignition switch and observe the D4 indicator light.

Codes 1 through 9 are indicated by individual short blinks. Codes 10 and above are indicated by a series of long and short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the code. After determining the code, refer to the electrical system Symptom-to-Component chart on pages 14-54 and 55.

Some PGM-FI problems will also make the D4 indicator light come on. After repairing the PGM-FI system, disconnect the BACK UP fuse No. 47 (7.5 A) in the under-hood fuse/relay box for more than 10 seconds to reset the TCM memory, then recheck.

NOTE: Disconnecting the BACK UP fuse also cancels the radio anti-theft code, preset stations and the clock setting.
