Power Window Switch: Testing and Inspection
INSPECTION1. 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.
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.
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 front.
2. Check the resistance between terminals of the switch - power window sub front.
3. If the inspection result is not within the standard, replace the switch - power window sub front.
