ECM/PCM Reset Procedure
WARNING: This page does not describe the selected car, but rather 126 other vehicles, including the 1999 Volvo V70, 1999 Volvo S80, 1999 Volvo S70, 1999 Volvo C70, and 1999 Volkswagen Passat. However, it is still accessible from the selected car via links, so may be relevant.
Using Honda PGM Tester or OBD-II scan tool, clear ECM/PCM memory. Follow manufacturer's instructions. To reset ECM/PCM without scan tool, turn ignition off. Remove BACK UP or CLOCK/RADIO (7.5-amp) fuse from underhood fuse/relay box for 10 seconds.
NOTE:
If no DTCs exist and SCS is connected, MIL will stay illuminated with ignition on.
