1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. 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).
4. Check for DTCs (see page 11-3). If a DTC is present, diagnose and repair the cause before continuing
with this test.
5. Start the engine. Hold the engine speed at 3,000 rpm with no load (in N or P (A/T model) or
neutral (M/T model)) until the radiator fan comes
on, then let it idle.
6. Check the idle speed (see page 11-309).
7. Jump the SCS line with the HDS.
8. Connect the timing light to the service loop (white tape). 9. Aim the light toward the pointer (A) on the cam
chain case. Check the ignition timing under a no
load condition (headlights, blower fan, rear window
defogger, and air conditioner are turned off).
10. If the ignition timing differs from the specification, check the cam timing. If the cam timing is OK,
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
system work properly, and the ECM/PCM was
substituted, replace the original ECM/PCM
(see page 11-228).
11. Disconnect the HDS and the timing light.

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).

1. Make sure the battery connections are good and the battery is sufficiently charged.
2. Connect the alternator, regulator, battery & starter tester (OTC3131) to the battery as shown.
3. Start the engine. Hold the engine speed at 3,000 rpm with no load (in N or P (A/T model) or
neutral (M/T model)) until the radiator fan comes
on, then let it idle.
4. Do the CHARGING SYSTEM TEST.
Go to step 5.
If the voltage is less than 13.5 V, go to
alternator control circuit troubleshooting (see page
4-29). If the voltage is over 15.1 V and amperage is
less than 87.5 A, replace the alternator (see page
4-34) or repair the alternator (see page 4-38). 5. Check the diode condition on the display.
The diode is OK. Troubleshooting is
complete.
If the display indicates BAD, replace the
alternator (see page 4-34) or repair the alternator
(see page 4-38), then retest.
NOTE: If the display indicates N/A, the diode
pattern could not be diagnosed. Repeat the test
again. If test is complete, use multimeter to
perform further pinpoint testing, then retest.
Does the display indicate the voltage is within 13.5 15 .1 V t he amper age i s 87 .5 A or mor e? Does t he d i spl ay i nd i cat e GOOD?
