GENERAL TROUBLESHOOTING INFORMATION

HOW TO CHECK FOR DTCS WITH THE HONDA DIAGNOSTIC SYSTEM

When the powertrain control module (PCM) senses an abnormality in the input or output systems, the D
indicator (A) in the gauge assembly (B) will usually blink.

When the data link connector (DLC) (A) (located under the left end of the dash) is connected to the Honda
diagnostic system (HDS), it will indicate the diagnostic trouble code (DTC) when the ignition switch is turned
ON (II).

Fig. 4: Locating The Data Link Connector (DLC)

If the D indicator or malfunction indicator lamp (MIL) has been reported on, or if a driveability problem is
suspected, follow this procedure:

1. Connect the HDS to the DLC. (See the HDS user's manual for specific instructions.)

2. Turn the ignition switch ON (II), select A/T system and observe the DTC in the DTCs MENU on the

tester 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 DTCs, and no problems were
detected in the fuel and emissions circuit of the PCM).

5. Clear the DTC and data.

6. Drive the vehicle for several minutes under the same conditions as those indicated by the freeze data, and

then recheck for a DTC. If the A/T DTC returns, go to the DTC troubleshooting Index. If the DTC does
not return, there was an intermittent problem within the circuit; make sure all pins and terminals in the
circuit are tight.
