Troubleshooting Procedures

Checking the Diagnostic Trouble Code (DTC)
with an OBD II Scan Tool or Honda PGM Tester

When the PCM senses an abnormality in the input or output systems, the indicator light in the gauge assembly will

blink. When the 16P Data Link Connector (DLC) (located behind the ashtray) is connected to the OBD II Scan Tool or Honda
PGM Tester as shown, the scan tool or tester will indicate the Diagnostic Trouble Code (DTC) when the ignition switch is

turned ON (II).

If the indicator light or the MIL has been reported on, or if a driveability problem is suspected, follow this procedure:

1. Connect the OBD II Scan Tool (conforming to SAE J1978) or Honda PGM Tester to the 16P DLC.

(See the OBD II Scan Tool or Honda PGM Tester user's manual for specific instructions. If you are using the Honda
PGM Tester, make sure it is set to the SAE DTC type.)

2. Turn the ignition switch ON (II), and observe the DTC on the screen.

3. Record all fuel and emissions DTCs, A/T DTCs, and freeze data.

4. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC (except for DTC

P0700). DTC P0700 means there is one or more A/T DTC, and no problems were detected in the fuel and emissions circuit

of the PCM.

5. Get the anti-theft code for the radio, then write down the radio station presets.

6. Reset the memory with the PGM Tester or by removing the BACK UP fuse in the under-hood fuse/relay box for more

than 10 seconds.

7. Drive the vehicle for several minutes at speeds over 30 mph (50 km/h), and then recheck for DTCs. If the A/T DTC

returns, go to the Symptom-to-Component Chart (page

14-56

and

14-57

). If the DTC does not return, there was an inter-

mittent problem within the circuit. Make sure all pins and terminals in the circuit are tight, and then go to step 8.

8. Enter the anti-theft code for the radio, reset the radio preset stations, and set the clock.
