Mode FC0 - Back-Up Clear

CLEARING CODES STORED IN MEMORY

The current trouble history code is deleted from the monitor when the ignition switch is turned OFF after performing on-board diagnostics. However, past trouble history codes are stored in the TCM. They remain in memory even when the ignition switch is turned OFF because there is a memory back-up battery. The current trouble history code can be displayed again when on-board diagnostics is performed after driving, provided that no inspection or repair has been made.

To delete past trouble history codes, first perform on-board diagnostics after inspection and repair using the current trouble history code, then confirm that no trouble codes are displayed. Next, select and execute a particualr mode on the select monitor.

NOTE: Since the past trouble history is deleted with this procedure, it is necessary to inspect and make repairs according to the trouble codes, and to ensure that no trouble code is indicated in on-board diagnostics. The past trouble history will not be lost, provided inspection and repairs are performed according to the current trouble history code, and that no trouble remains.
