Main Switch

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

CAUTION: Since the driver's side power window switch is controlled by CPU, do not check continuity for switch alone with the circuit tester. Performing continuity check with circuit tester may damage the driver's side power window switch circuit.
  1. Disconnect the ground cable from battery.
  2. Remove the power window main switch. < Ref. to REMOVAL , Power Window Control Switch. >
  3. Connect the battery and the Subaru Select Monitor to the power window main switch connector.
    CAUTION: Never mix up the terminals when connecting the power window main switch connector and battery. If connected to a wrong terminal, the power window main switch may be damaged.
    NOTE:
    • When the battery is connected to the power window main switch, the letters "AUTO" on the driver's side knob illuminates.
    • For detailed procedures, refer to SYSTEM WIRING DIAGRAMS .

  4. Operate the driver's side power window switch knob 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 knob is operated for window DOWN operation.
