Diagnostics: Other Subaru Forester SF рестайлинг

SUPPLEMENTAL RESTRAINT SYSTEM "AIRBAG"

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

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).

ATF LEVEL

Make sure that ATF level is in the specification.

Checking ATF Fluid Level. Scheme 634

FRONT DIFFERENTIAL OIL LEVEL

Make sure that front differential oil level is in the specification.

Checking Front Differential Oil Level. Scheme 635

ABNORMAL DISPLAY ON AT OIL TEMP INDICATOR

When any on-board diagnostics item is malfunctioning, the display on the AT OIL TEMP indicator light blinks from the time the malfunction is detected after starting the engine until the ignition switch is turned OFF. The malfunctioning part or unit can be determined by a trouble code during on-board diagnostics operation. Problems which occurred previously can also be identified through the memory function. If the AT OIL TEMP indicator does not show a problem (although a problem is occurring), the problem can be determined by checking the performance characteristics of each sensor using the select monitor. Indicator signal is as shown in the figure.

Abnormal Display On AT Oil Temperature Indicator (Indicator Light Blinks). Scheme 636

CLEAR MEMORY

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

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.
