1. Connect the Honda Diagnostic System (HDS) to thedata 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, and check the OIL PRESSURE SWITCH in the PGM-FI DATA LIST with the HDS.
Replace the gauge control module (tach)
(see page 22-277).
Go to step 6.
6. Turn the ignition switch to LOCK (0).
7. Disconnect the oil pressure switch connector.
8. Start the engine, and check the OIL PRESSURE SWITCH in the PGM-FI DATA LIST with the HDS.
Turn the ignition switch to LOCK (0), then go
to step 9.
Turn the ignition switch to LOCK (0), then go
to step 10.
9. Check the oil pressure switch (see page 8-9).
Do the oil pressure test (see page 8-10).
Replace the oil pressure switch (see page 8-9). 10. Turn the ignition switch to ON (II), and 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.
11. Disconnect ECM/PCM connector B (44P).
12. Check for continuity between the oil pressure switch connector and body ground.
Repair a short to ground in the wire between
the oil pressure switch and ECM/PCM connector
terminal B7.
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).
