Troubleshooting Proccdures
How To Begin Troubleshooting
When the Malfunction lndicator Lamp {MlL) has been reponed 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 ll
scan tool to the 16P Data Link Connector (DLC)
located behind the front console right side.
2. Turn the ignition switch ON (ll).
3. 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 scantool or Honda PGM Tester user's manuals for specific operating instructions.
. The scan tool or tester can read the Diagnostic Trouble Codes (OTC). freeze frame data, current data, and other
Engine Control Module (ECM) data.
. Freeze frame data indicates the engine conditions when the first malfunction, misfire or luel trim malfunction
was detected. lt can be useful information when troubleshooting.
B. When the MIL has not come on, but there is a driveability problem, refer to the Symptom Chart on page 11-36.
C. DTCS wjll be indicated by the blinking of the Malfunction lNdicator Lamp {MlL) with the SCS service connector con-
nected.
Connect the SCS service connector to Service Check Connector as shown. (The 2P Service Check Connector is
located under the dash on the passenger's side of the car,) Turn the ignition switch on (lll.

Engine Control Module (ECM) Reset Procedure
Either of the following actions will reset the ECM.
. Use the OBD ll scantool or Honda PGM Tester to clear the ECM'S memory.
NOTE: See the OBD ll scan tool or Honda PGM Tester use's manuals for specific operating instructions.
. Turn the ignition switch OFF. Remove the BACK UP (RADIO) (7.5 AI tuse from the under hood fuse/relay box for 10seconds.

lll. Final Procedure (this procedure must be done after any trou bleshooting )
1. Remove the SCS Service Connector if it is connected.
NOTE: lf the SCS service connectors is connected and there are no DTCS stored in the ECM, the MIL will stav onwhen the ignition switch is turned ON (ll).
2. Do the ECM Reset Procedure.
3. Turn the ignition switch OFF.
4. Disconnect the OBD ll scan tool or Honda PGM Tester from the Data Link Connector (16P|.
