Clearing Diagnostic Trouble Codes
NOTE:
Before clearing DTCs, obtain radio anti-theft code from customer. Note radio preset stations, as radio stations and clock setting will be cleared and must be reset. Radio anti-theft code must be reset for radio operation.
- Once repairs have been performed, DTCs must be cleared from PCM memory. A/T control system memory can be cleared using scan tool or removing BACK-UP fuse. To clear DTCs using scan tool, follow manufacturer's instructions. To clear DTCs without using scan tool, go to next step.
- Turn ignition off. Remove BACK-UP fuse (7.5-amp) from underdash fuse/relay box for at least 10 seconds. See Figure. This will clear PCM memory.
- Reinstall fuse. To re-enter radio anti-theft code, turn radio on. When CODE is displayed on radio, re-enter radio anti-theft code by using the radio station preset buttons. Reset clock and radio stations.
