Honda Accord 1998-2002 ECM Reset Tutorial and Guide

ECM/PCM Reset
How to Reset the ECM/PCM

You can reset the ECM/PCM in either of two ways:
  –  Use the OBD II scan tool or Honda PGM Tester to clear the ECM/PCM memory.
     See the OBD II scan tool or Honda PGM Tester user’s manuals for specific
     instructions.

 –  Turn the ignition switch OFF, and remove the No.13 CLOCK BACKUP fuse (7.5 A)
     (A) from the passenger’s under-dash fuse/relay box (B) for 10 seconds.
     NOTE:  If the No.13 CLOCK BACK UP (7.5 A) fuse is removed and engine is
     started, the MIL will come on and the PCM will store DTC P0560 (F23A4
     engine).

How to End a Troubleshooting Session (required after any troubleshooting)
  1. Reset the ECM/PCM as described above.
  2. Turn the ignition switch OFF.
  3. Disconnect the OBD II scan tool or Honda PGM Tester from the DLC.

     NOTE:  The ECM/PCM is part of the immobilizer system. If you replace the
     ECM/PCM, it will have a different immobilizer code. In order for the engine
     to start, you must rewrite the immobilizer code with the Honda PGM Tester.
