A/T Gear Position Indicator

D4 Indicator Circuit Troubleshooting

PCM CONNECTOR A (32P)

D4 IND (GRN/BLK)

PCM CONNECTOR D (16P)

ATP D4 (YEL)

1. Turn the ignition switch ON (II), and watch the D4

indicator.

Go to step 2.

If the light comes on for about 2 seconds and

then goes off, it’s OK. If it doesn’t come on at all, go
to step 12.

2. Make sure the HDS is not connected to the Data

Link Connector (DLC).

3. Turn the ignition switch OFF.

4. Disconnect the A (32P) and D (16P) connectors from

the PCM.

5. Turn the ignition switch ON (II).

6. Measure the voltage between the A14 terminal and

body ground.

Repair short to power in the wire between

the A14 terminal and the gauge assembly.

Go to step 7.

7. Turn the ignition switch OFF.

8. Reconnect the A (32P) and D (16P) connectors to

the PCM.

9. Turn the ignition switch ON (II).

10. Shift to any position other than D4.

11. Measure the voltage between the D9 terminal and

body ground.

Faulty PCM or gauge assembly.

Check for a short to ground in the wire

between the D9 terminal and the transmission
range switch. If the wire is OK, check the
transmission range switch.

12. Make sure the HDS is not connected to the DLC.

13. Shift to D4 position.

Check for loose terminal fit in the PCM

connectors and recheck the D4 indicator several
times. If the problem is intermittent, substitute a
known-good PCM and recheck. If the light then
works OK every time, replace the original PCM.

Go to step 14.

14. Turn the ignition switch OFF.

15. Disconnect the B (25P) connector from the PCM.

16. Check for continuity between body ground and B20

and B22 terminals.

Go to step 17.

Repair open in the wire(s) between the B20 or

B22 terminal and ground (G101), or repair poor
ground (G101).

17. Turn the ignition switch ON (II).

18. Measure the voltage between terminals B1 and B22,

and between terminals B9 and B20.

Go to step 19.

Repair open or short in the wire between the

B1 or B9 terminal and the PGM-FI main relay.

19. Turn the ignition switch OFF.

20. Reconnect the B (25P) connector to the PCM.

21. Connect the digital multimeter between the A14

and B20 or B22 terminals.

22. Turn the ignition switch ON (II).

Check for an open in the wire between the

A14 terminal and the gauge assembly. If the wire is
OK, check for a faulty D4 indicator bulb or a faulty
printed circuit board in the gauge assembly.

Go to step 23.

23. Turn the ignition switch OFF.

24. Disconnect PCM connector A (32P).

25. Check for continuity between the A14 terminal and

body ground.

Repair short to ground in the wire between

the A14 terminal and the gauge assembly.

Check for loose terminal fit in the PCM

connectors. Check the A/T gear position switch. If
necessary, substitute a known-good PCM and
recheck.

3. Turn the ignition switch OFF.

4. Disconnect PCM connector C (22P) and E (31P).

5. Turn the ignition switch ON (II).

6. Measure the voltage between PCM connector E5

terminal and body ground.

Repair short to power in the wire between

PCM connector terminal E5 and the gauge
assembly.

Go to step 7.

7. Turn the ignition switch OFF.

8. Reconnect PCM connectors C (22P) and E (31P).

9. Turn the ignition switch ON (II).

10. Shift to any position other than D4.

11. Measure the voltage between PCM connector

terminal C13 and body ground.
