NOTE: Check for stored DTCs in the PGM-FI before
troubleshooting the charging system indicator.
1. Turn the ignition switch to ON (II).
Go to step 2.
Go to step 14.
2. Start the engine. Hold the engine speed at 2,000 rpm for 1 minute.
Charging system indicator circuit is OK. Go
to the alternator and regulator circuit
troubleshooting (see page 4-28).
Go to step 3.
3. Do the gauge control module self-diagnostic function procedure (see page 22-241).
Go to step 4.
Replace the gauge control module (tach)
(see page 22-277).
4. Turn the ignition switch to LOCK (0).
5. Disconnect the alternator 4P connector.
6. Turn the ignition switch to ON (II).
Replace the alternator (see page 4-34), or
repair the alternator (see page 4-38).
Go to step 7. 7. Turn the ignition switch to LOCK (0).
8. Connect the Honda Diagnostic System (HDS) to the
data link connector (DLC) (see step 2 on page 11-3).
9. Turn the ignition switch to ON (II).
10. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain
control module (PCM). If it does not communicate,
troubleshoot the DLC circuit (see page 11-204).
11. Jump the SCS line with the HDS, then turn the ignition switch to LOCK (0).
NOTE: This step must be done to protect the ECM/
PCMfromdamage.
12. Disconnect ECM/PCM connector B (44P).
13. Check for continuity between ECM/PCM connector terminal B42 and body ground.
Repair short to ground in the wire between
alternator 4P connector terminal No. 3 and ECM/
PCM connector terminal B42.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
