NOTE:
. See section 11 when the malfunction indicator lamp(MlL) comes on.
. Perform an input test for the ignition control module(lCM) after finishing the fundamental tests for the
ignition system and the fuel and emissions systems.
. '97 -'98 models: The tachometer should operate nor-
mally if the ICM is OK.
L Remove the distributor ignition (Dl) cap, the distrib-
utor ignition (Dl) rotor, and the leak cover.

Turn the ignition switch ON {ll). Check for voltage
between the BLK,^/EL wire and body ground. There
should be battery voltage.
. lf there is no battery voltage, check the BLK/rEL
wire betlveen the ignition switch and the lclvl.
. lf there is baftery voltage, go to step 4.
Turn the ignition switch ON (ll). Check for voltage
between the WHT/BLU wire and body ground. There
should be battery voltage.
. lf there is no batteryvoltage, check:- ignition coil.- WHT/BLU wire between the ICM and ignition
corl.
. lf there is battery voltage, go to step 5,
'97 model: Disconnect the ECM/PCM connector A(32P). Check for continuity on the YEL/GRN wire
between the ICM and ECM/PCM. There should be
continuity.'98 - 00 models: Disconnect the ECM,PCM connector
B (25P). Check for continuity on the YEUGRN wire
between the ICM and ECM/PCM. There should be
continuity.
Check for continuity on the YEUGRN wire to body
ground. There should be no continuity.
Reconnect the ECM/PClvl connector.
'97 -'98 models: Check for continuity on the BLU
wire between the test tachometer connector and the
lCM. There should be continuity.
'97 -'98 models: Check for continuity on the BLU
wire to body ground. There should be no continuity.
lf all the tests are normal, replace the lCM.

Troubleshooting
lf the charging system light does not come on or does not go off, or the battery is dead or low, test the following items inthe order listed below:
1. Battery (see section 23)
2. Charging system light
3. Voltage
4. Alternator control system (U.S.A. model)
5. Alternator/regulator

Troubleshooting
Troubleshooting Procedures
How To Begin Troubleshooting
When the Malfunction indicator Lamp (MlLl has been reported on, or there is a driveability problem, use the appropri-ate procedure below to diagnose and repair the problem.
A. When the MIL has come on:
1. Connect the Honda PGM Tester or an OBD Il scan tool to the 16P Data Link Connector (DLC) located behind theright side of the center console.
Turn the ignition switch ON (ll).
Check the DTC and note it. Also check and note
the freeze frame data.
Refer to the Diagnostic Trouble Code Chart and
begin troubleshooting.
NOTE:
. SeetheOBDll scan tool or Honda PGM Tester user's manuals for specific operating instructions.. The scan tool or tester can read the Diagnostic Trouble Codes (DTC), freeze frame data, current data, and otherEngine Control Module (ECM}/Powertrain Control Module (PCM) data.. Freeze frame data indicates the engine conditions when the first malfunction, misfire or fuel trim malfunction wasdetected. lt can be useful information when troubleshootino.
B. When the MIL has not come on, but there is a driveability problem, refer to the Symptom Chart on page 11-64.
C. DTCs will be indicated by the blinking of the Malfunction Indicator Lamp {MlL) with the SCS service connector con-nected.
Connect the SCS service connector to Service Check Connector as shown. {The 2P Service Check Connecror rslocated behind the right side of the center console.) Turn the ignition switch ON 0l).

ll. Engine Controt Module (EcM)/Powertrain Control Module {PCM) Reset Procedure
Either of the following actions will reset the ECM/PCM.
. use the oBD ll scan tool or Honda PGM Tester to clear the ECM's/PCM's memory. (see the oBD ll scan tool or
Honda PGM Tester user's manuals for specific operating instructions )
. Turn the ignition switch oFF. Remove the BACK UP (RADIO) (7.5 A) fuse from the under-hood fuse/relay box for 10
seconos.
lll. Final Procedure {this procedure must be done after any troubleshooting)
1. Remove the SCS Service Connector if it is connected. lf the SCS service connector is connected. and there are no
DTCS stored in the ECM/PCM, the MIL will stay on when the ignition switch is turnsd oN (ll).
2. Do the ECM/PCM Reset Procedure.
3. Turn the ignition switch OFF
4. Disconnect the OBD ll scan tool orHonda PGM Tester from the Data Link Connector ( 16P)'
