WITH SUBARU SELECT MONITOR

Refer to SUBARU SELECT MONITOR for information about how to obtain and understand diagnostic trouble codes (DTC). Refer to OPERATION , Subaru Select Monitor.

WITHOUT SUBARU SELECT MONITOR

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

CLEAR MEMORY

  1. Removal of TCM connector (B54) and (B55) (for at least two minutes)
  1. The TCM connector (B54) and (B55) is located in the line to memory back-up power supply. Removal of this connector clears the previous diagnostic trouble codes (DTC) stored in TCM memory.
