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

–
1991 Prelude with 2.1L engine:
Remove the CLOCK Fuse, # 35.

• Replace fuse. 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.
