Pinpoint Test D: A Single Power Window Is Inoperative - RH Front

NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

D1 CHECK THE RH FRONT POWER WINDOW OPERATION FROM LH FRONT CONTROL SWITCH
- Ignition ON.
- Attempt to operate the RH front window from the LH front window control switch.
- Does the RH front window operate when using the LH front window control switch?
- Yes : GO to D2.
- No : GO to D4.
D2 CHECK CIRCUIT CPW14 (VT/WH) FOR VOLTAGE
- Disconnect: RH Front Window Control Switch C604.
- Ignition ON.
- NOTE: Make sure the LH window control switch lockout switch is in the UNLOCK position.
- Measure the voltage between RH window control switch C604-3, circuit CPW14 (VT/WH), harness side and ground.

- Is the voltage greater than 10 volts?
- Yes : INSTALL a new RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- No : GO to D3.
D3 CHECK THE LH FRONT WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: LH Front Window Control Switch C504.
- Carry out the LH front window control switch component test.
  Refer to SYSTEM WIRING DIAGRAMS for component testing.
- Did the window control switch pass the component test?
- Yes : REPAIR open in circuit CPW14 (VT/WH). TEST the system for normal operation.
- No : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- D4 CHECK THE RH FRONT POWER WINDOW OPERATION FROM RH FRONT CONTROL SWITCH
  - Ignition ON.
  - Attempt to operate the RH front window from the RH front window control switch.
  - Does the RH front window operate when using the RH front window control switch?
  - Yes : GO to D5.
  - No : GO to D6.
- D5 CHECK CIRCUITS CPW13 (BN/YE) AND CPW12 (GN/OG) FOR AN OPEN
  - Measure the resistance between RH front window control switch C604-1, circuit CPW13 (BN/YE), harness side and LH front window control switch C504-11, circuit CPW13 (BN/YE), harness side.

  - Is the voltage greater than 10 volts?
  - Yes : GO to D7.
  - No : VERIFY Smart Junction Box (SJB) circuit breaker 47 (30A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
  If not OK, REFER to the appropriate Systems Wiring Diagram to identify the possible causes of the circuit short. REPAIR the circuit. TEST the system for normal operation.
- D7 CHECK THE GROUND TO THE RH WINDOW CONTROL SWITCH
  - Ignition OFF.
  - Measure the resistance between RH front window control switch C604-8, circuit GD145 (BK/BU), harness side and ground.

  - No : REPAIR the circuit. TEST the system for normal operation.
- D8 CHECK THE RH FRONT WINDOW CONTROL SWITCH
  - Carry out the RH front window control switch component test.
    Refer to SYSTEM WIRING DIAGRAMS for component testing.
  - Did the RH front window control switch pass the component test?
  - Yes : GO to D9.
  - No : INSTALL a new RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- D9 CHECK CIRCUITS CPW19 (VT) AND CPW20 (WH/OG) FOR AN OPEN
