Subaru Crosstrek Service Manual: Inspection

GLASS/WINDOWS/MIRRORS > Power Window Control Switch

INSPECTION

1. MAIN SWITCH

Driver’s seat

CAUTION:

Since the switch - power window main is controlled by CPU, do not check continuity for switch alone with the circuit tester. Performing continuity check with circuit tester can damage the switch - power window main circuit.

Check output from the switch - power window main to the driver’s side motor using the oscilloscope function in the Subaru Select Monitor.

1. Remove the switch - power window main.

2. Connect the battery and the Subaru Select Monitor to the switch - power window main terminal.

CAUTION:

Never mix up the terminals when connecting the harness connector of the switch - power window main and the battery. If the connection is wrong, the switch - power window main may be damaged.

NOTE:

When the battery is connected to the switch - power window main terminal, the letters “AUTO” on the driver’s side knob illuminates.

For detailed procedures, refer to “Subaru Select Monitor Operation Manual”.

3. Operate the switch - power window main and check the output.

NOTE:

Since output time during window UP operation is extremely short, it cannot be checked without using a measuring instrument such as oscilloscope. Output is constantly produced while the switch is operated for window DOWN operation.
