Clearing Trouble Codes

Current trouble codes shown on the display are cleared by turning the ignition switch OFF after conducting self-diagnosis operation. Previous trouble codes, however, cannot be cleared since they are stored in the ECU memory which is operating on the back-up power supply. These trouble codes can be cleared by removing fuse 14 (located under the right lower portion of the instrument panel).

^ The No. 14 fuse is located in the line to the memory back-up power supply of the TCU and ECU (MPFI). Removal of this fuse clears the previous trouble codes stored in the TCU and ECU (MPFI) memory.

^ Be sure to remove the No. 14 fuse for at least one minute. Otherwise, trouble codes may not be cleared.
