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.
Inspection conditions | Output time | Standard |
AUTO UP | Approx. 130 ms | Battery voltage |
UP | ||
OFF | — | 0 V |
DOWN | During switch operation | Battery voltage |
AUTO DOWN | Approx. 300 ms |
4. If the inspection result is not within the standard, replace the switch - power window main.
• Except for driver’s seat
1. Check the resistance between terminals of the switch - power window main.
Terminal No. | Inspection conditions | Standard | |
Passenger’s seat | 14 — 8 1 — 2 | UP | Less than 1 ? |
14 — 2 14 — 8 | OFF | 1 M? or more | |

1 — 6 1 — 7 6 — 7 | Less than 1 ? | ||
14 — 6 1 — 7 | DOWN | Less than 1 ? |
2. If the inspection result is not within the standard, replace the switch - power window main.
2. SUB-SWITCH
1. Remove the switch - power window sub.
2. Check the resistance between terminals of the switch - power window sub.
Terminal No. | Inspection conditions | Standard | |
Passenger seat, rear | 6 — 5 8 — 7 | UP | Less than 1 ? |
7 — 6 4 — 6 | OFF | 1 M? or more | |
5 — 4 8 — 7 | Less than 1 ? | ||
6 — 8 5 — 4 | DOWN | Less than 1 ? |
3. If the inspection result is not within the standard, replace the switch - power window sub.
