Troubleshooting

Troubleshooting Procedures

I. How To Begin Troubleshooting

When the Malfunction Indicator Lamp (MIL) 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 II scan tool to the Data Link Connector (DLC) located on the center con-

sole behind the ashtray.

(MIL)

2. Turn the ignition switch ON (II).

3. Check the Diagnostic Trouble Code (DTC) and note

it. Also check and note the freeze frame data.
Refer to the DTC Chart (see page

11-53

) and begin

troubleshooting.

NOTE:
• See the OBD II scan tool or Honda PGM Tester user's manuals for specific operating instructions.
• The scan tool or tester can read the DTC, freeze frame data, current data, and other Powertrain Control Module

(PCM) data.

• Freeze frame data indicates the engine conditions when the first malfunction, misfire or fuel trim malfunction was

detected. It 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

11-44

.

C. DTCs will be indicated by the blinking of the MIL with the SCS service connector connected.

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 vehicle.) Turn the ignition switch ON (II).
