What to do with the Trouble Codes
Look up the code definitions listed in
Section 9, “Honda Code Meanings.”
At this point you can either:
• Have your vehicle professionally
serviced. Trouble codes indicate
problems found by the computer.
or,
• Repair the vehicle yourself using
trouble codes to help pinpoint the
problem. Refer to Section 3, “Using
Codes.” Be sure to erase any trouble
codes from the computer’s memory
after repairs are completed, as
follows.
Erasing Trouble Codes after Repair
• Verify that the
ignition key is in
the OFF position.
• Remove the negative (-) battery cable
or indicated fuse and wait 15 seconds.
–
1986 to 1987 ALL:
Remove the negative (-) battery
cable.
–
1988 to 1989 Accord LXi:
Remove the CLOCK Fuse, # 11.
–
1988 to 1990 Civic, & CRX:
Remove the HAZARD Fuse, # 34.
–
1988 to 1990 Prelude (CARB):
Remove the EFI/ECU Fuse, # 38.
–
1988 to 1991 Prelude (INJ):
Remove the CLOCK Fuse, # 35.
–
1990 Accord:
Remove the BACKUP Fuse, # 24.
–
1991 Civic, CRX:
Remove the ECU Fuse, # 34.
• All the trouble codes are now erased
from computer memory!
• Replace fuse or reconnect battery
cable. You may have to reset the
vehicle clock, radio stations, and so
on.
Important: The computer has a
“learning” ability to take care of minor
variations in engine control operation.
Whenever you erase the computer
memory, the computer has to “relearn”
various things. Vehicle performance may
be noticeably different until it “relearns”.
This temporary situation is normal. The
“learning” process takes place during
warm engine driving.
