Indicator Light Circuit Troubleshooting
[D5] Indicator Circuit Troubleshooting
1. Turn the ignition switch ON (II), and watch the [D5] indicator.
Does the [D5] 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 normal. If it doesn't come on at all, go to step 16.
2. Make sure the Honda PGM Tester is not connected to the data link connector.
3. Turn the ignition switch OFF.
4. Disconnect the battery negative terminal.
5. Disconnect PCM connector A (32P).
6. Reconnect the battery negative terminal.
7. Turn the ignition switch ON (II).
8. Measure the voltage between PCM connector terminal A14 and body ground.
Is there voltage?
YES - Repair short to power in the wire between PCM connector terminal A14 and the gauge assembly.
NO - Go to step 9.
9. Turn the ignition switch OFF.
10. Disconnect the battery negative terminal.
11. Reconnect PCM connector A (32P).
12. Reconnect the battery negative terminal.
13. Turn the ignition switch ON (II).
14. Shift to any position other than D5.
15. Measure the voltage between PCM connector terminal D9 and body ground.
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,
16. Make sure the Honda PGM Tester is not connected to the data link connector.
17. Shift to D5 position.
Does the D5 indicator come on?
YES - Check for loose terminal fit in the PCM connector terminal A14 and recheck the D5 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 18.
18. Turn the ignition switch OFF.
19. Disconnect the battery negative terminal.
20. Disconnect PCM connector B (25P).
