Troubleshooting Procedures
Checking the Diagnostic Trouble Code (DTC)
with an OBD II Scan tool or Honda PGM Tester
When the TCM 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).
When the indicator light has been reported on, connect the OBD II Scan Tool conforming to SAE J1978 or Honda PGM
Tester to the DLC (16P) behind the ashtray. Turn the ignition switch on (II), and observe the DTC on the screen of the OBD II
Scan Tool or Honda PGM Tester. After determining the DTC, refer to the electrical system Symptom-to-Component Chart
on page 14-56 and 14-57.
NOTE: See the OBD II Scan Tool or Honda PGM Tester user's manual for specific instruction.

Some PGM-FI problems will also make the indicator light come on. After repairing the PGM-FI system, disconnect the
BACK UP RADIO fuse (10 A) in the under-hood fuse/relay box for more than 10 seconds to reset the TCM memory, then
retest.
NOTE: Disconnecting the BACK UP RADIO fuse also cancels the radio anti-theft code, preset stations and the clock setting.
Get the customer's code number, and make note of the radio presets before removing the fuse so you can reset them.
