Without SUBARU Select Monitor

Current trouble codes shown on the display are cleared by turning the ignition switch OFF after conducting on-board diagnostics operation. Previous trouble codes, however, cannot be cleared since they are stored in the TCM memory which is operating on the back-up power supply. These trouble codes can be cleared by removing the specified TCM connector for at least 2 minutes.

CLEAR MEMORY: 

1. Without VDC system and SPORT shift:  Remove the TCM connector (B55).
2. With VDC system or SPORT shift:  Remove the TCM connector (B56).

• The TCM connector is located in the line to the memory back-up power supply of the TCM. Removal of this fuse clears the previous trouble codes stored in the TCM memory.
• Be sure to remove the TCM connector for at least the specified length of time. Otherwise, trouble codes may not be cleared.
