D Indicator Circuit Troubleshooting
1. Turn the ignition switch ON (II), and watch the D
indicator.
Does the D indicator come on and stay on?
YES Go to step 2.
NO If the indicator comes on for about 2 seconds
and then goes off, it's OK. If it doesn't come on at
all, go to step 13.
2. Make sure the HDS is not connected to the data link
connector.
3. Turn the ignition switch OFF.
4. Disconnect PCM connector A (32P).
5. Turn the ignition switch ON (II).
6. Measure the voltage between PCM connector
terminal A14 terminal and body ground.
PCM CONNECTOR A (32P)
D5 IND (GRN/BLK)
Wire side of female terminals
Is there voltage?
YES Repair short to power in the wire between
PCM connector terminal A14 and the gauge
assembly.
NO Go to step 7.
7. Turn the ignition switch OFF.
8. Reconnect PCM connector A (32P).
9. Turn the ignition switch ON (II).
10. Shift to any position other than D.
11. Measure the voltage between PCM connector
terminal D9 and body ground.
PCM CONNECTOR D (16P)
Wire side of female terminals
Is there voltage?
YES Faulty PCM or gauge assembly.
NO Check for a short to ground in the wire
between PCM connector terminal D9 and the
transmission range switch. If the wire is OK, check
the transmission range switch.
12. Turn the ignition switch ON (II).
13. Shift to the D position.
Does the D indicator come on?
YES Check for loose terminal fit in the PCM
connector A14 and recheck the D indicator several
times. If the problem is intermittent, substitute a
known-good PCM and recheck. If the indicator then
works OK every time, replace the original PCM.
NO Go to step 14.
14. Turn the ignition switch OFF.
