Chccking the Diagnostic Trouble Code IDTC)with an OBD ll Scan tool or Honda PGM Tester
when the PCM senses an abnormality in the input or output systems, the pl indicator light in the gauge assembly willblink. When the 16P Data Link Connector (DLC) (located under the dash on the driver,s side) is connected to the OBD llScan Tool or Honda PGM Tester as shown, the scan tool or tester will indicate the Diagnostic Trouble Code (DTC) whenthe ignition switch is turned ON{ll).
lf the El indicator light or the MIL has been reported on, or lf a driveability problem is suspected, follow this procedure:
1. Connect the OBD ll Scan Tool (conforming to SAE J19781 or Honda PGM Tester to rhe 16p DLC. (See the OBD ll ScanTool or Honda PGM Tester user's manual for specific instructions. lf you are using the Honda PGM Tester, make sure itis set to the SAE DTC type.)
2. Turn the ignition switch ON (lll, and observe the DTC on the screen,3, Record all fuel and emission DTCS, A/T DTCS, and freeze data.4 lf there is a fuel and emissions DTC, first checkthe fuel and emissions system as indicated bythe DTC (except for DTCP0700). DTC P0700 means there is one or more A,/T DTC, and no problems were detected in the fuel and emissions cir-cuit of the PCM.
5. Write down the radio station oresets.
6. Reset the memory with the PGM Tester or by removing the BACK UP fuse in the passenger's under-dash fuse/relay boxfor more than 10 seconds.
7. Drive the vehicle for several minutes at speeds over 30 mph (50 km/hr), and then recheck for DTCS. lf the A"/T DTCreturns, go to the Symptom-to Component Chart on pages 14-52 and 14-53 for'96 - 98 models, and pages 14-54 and14-55 for the'99 - 00 models, lf the DTC does not return, there was an intermittent problem within the circuit. Makesure all pins and terminals in the circuit are tight, and then go to step g.
8. Reset the radio preset stations, and set the clock.

Troubleshooting Procedures
l. How To Begin Troubleshooting
When the E indicator light has been reported on, use the appropriate procedure below to diagnose and repatr theproDlem.
A. When the @ indicator light has come on:
l connect the Honda PGM Tester or an oBD ll Scan Tool to the 16P Data Link Connector (DLc) located near the leftkick panel.
Turn the ignition switch ON (ll).
Check the DTC and note it. Also check and notethe freeze frame data.
Refer to the Diagnostic Trouble Code Chart andbegin troubleshooting.
INOICATORLIGHT
NOTE: SeetheOBDll Scan Tool or Honda PGM Tester user's manuals for specific operating instructions.
Some PGM-FI problems will also make the E indicator light come on. After repairing the pGM-Fl system, disconnect theBACK UP fuse (7.5 Al in the under-hood fuse/relay box for more than l0 seconds to reset the TCM or PCM memory, rnenrecheck.
NOTE: Disconnecting the BACK UP fuse also cancels the radio preset stations and the clock setting. Make note of theradio presets before removing the fuse so you can reset them,
