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,
