CAUTION

  1. Supplemental Restraint Systems "Airbag"

Airbag system wiring harness is routed near the transmission control module (TCM).

CAUTIONAll airbag system wiring harness and connectors are colored yellow. Do not use electrical test equipment on these circuit. Be careful not to damage airbag system wiring harness when performing diagnostics and servicing the TCM.
  1. Measurement

When measuring voltage and resistance of the ECM, TCM or each sensor, use a tapered pin with a diameter of less than 0.64 mm (0.025 in) in order to avoid poor contact. Do not insert the pin more than 5 mm (0.20 in).

BATTERY

Measure battery voltage and specific gravity of electrolyte.

  1. Standard voltage: 12V or more
  2. Specific gravity: Above 1.260

TRANSMISSION GROUND

Make sure that the ground terminal bolt is tightened securely.

WITH SUBARU SELECT MONITOR

Refer to SUBARU SELECT MONITOR for information about how to obtain and understand trouble codes. See Subaru Select Monitor .

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 fuse (located under the light or left lower position of the instrument panel).

CLEAR MEMORY

  1. Removal of No. 4 fuse (for at least one minute)
  1. The No. 4 fuse 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.
  2. Be sure to remove the No. 4 fuse for at least the specified length of time. Otherwise, trouble codes may not be cleared.

Refer to SUBARU SELECT MONITOR for information about how to clear trouble codes. (Scheme 850)
