2000 HONDA CR-V air box

PCM Reset Procedure
'1. Turn the ignition switch off
2. Remove the BACK UP fuse (7.5 A) from the under-hood fuse/relay box for 10 seconds to reset the PCM.
NOTE:
. Disconnecting the BACK Up fuse also cancels the radio preset stations and clock setting Make note of the radio
presets before removing the fuse so you can reset them
. The PCM memorv can also be cleared by using the OBD ll Scan Tool or Honda PGM Tester'
UNDER.HOODFUSE/RELAY BOX
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).
