Final Proceduro
This procedure must be done after any troubleshooting.
1. Turn the ignition switch OFF.
2. Reset the PCM.
3. Disconnect the OBD ll Scan Tool or Honda PGM Tester from the Data Link Connector (16P), or remove the special tool
from the Service Check Connector (2P).
4. Turn the ignition switch ON (ll), and set the radio presets and clock setting'
5, To verify that the problem is repaired. test-drive the vehicle for several minutes at speeds over 30 mph (48 km/h).
