Part 1:

Part 2:

e. Measure the resistance of the connector.
If the result is not as specified, the switch may have a malfunction.

HINT*: An operation permission signal is output from terminal PCT of the master switch to each switch. If the voltage is not as specified, there may be another malfunction in the vehicle. An operation permission signal is also output through the multiplex communication line to each switch. If the signal from terminal PCT is not input to the switch but the signal from the multiplex communication line is input, the window can operate.




3. CHECK MULTIPLEX NETWORK SWITCH ASSEMBLY (REAR LH)
a. Disconnect the T1 switch connector.




b. Measure the voltage and resistance of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.

HINT*: Terminals SEL1 and SEL2 are used to verify which power window control system (passenger side power window, rear RH power window or rear LH power window) is activated when the master switch's remote operation is performed. The passenger side power window switch's SEL1 and SEL2 terminals are not connected to the body ground. Only the rear RH power window switch's SEL1 terminal is connected to the body ground. Also, only the rear LH power window switch's SEL2 terminal is connected to the body ground.

c. Reconnect the T1 switch connector.
d. Reset the power window regulator motor.

Part 1:

Part 2:

e. Measure the voltage of the connector.
If the result is not as specified, the switch may have a malfunction.

HINT*: An operation permission signal is output from terminal PCT of the master switch to each switch. If the voltage is not as specified, there may be another malfunction in the vehicle. An operation permission signal is also output through the multiplex communication line to each switch. If the signal from terminal PCT is not input to the switch but the signal from the multiplex communication line is input, the window can operate.




4. MULTIPLEX NETWORK SWITCH ASSEMBLY (REAR RH)
a. Disconnect the S1 switch connector.




b. Measure the voltage and resistance of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.

HINT*: Terminals SEL1 and SEL2 are used to verify which power window control system (passenger side power window, rear RH power window or rear LH power window) is activated when the master switch's remote operation is performed. The passenger side power window switch's SEL1 and SEL2 terminals are not connected to the body ground. Only the rear RH power window switch's SEL1 terminal is connected to the body ground. Also, only the rear LH power window switch's SEL2 terminal is connected to the body ground.

c. Reconnect the S1 switch connector.
d. Reset the power window regulator motor.

Part 1:

Part 2:

e. Measure the voltage of the connector.
If the result is not as specified, the switch may have a malfunction.

HINT*: An operation permission signal is output from terminal PCT of the master switch to each switch. If the voltage is not as specified, there may be another malfunction in the vehicle. An operation permission signal is also output through the multiplex communication line to each switch. If the signal from terminal PCT is not input to the switch but the signal from the multiplex communication line is input, the window can operate.




5. CHECK FRONT MULTIPLEX NETWORK DOOR ECU LH (DRIVER DOOR ECU)
a. Disconnect the N3 and N4 ECU connectors.

Part 1:

Part 2:

b. Measure the voltage of the wire harness side connectors.
If the result is not as specified, there may be a malfunction on the wire harness side.

HINT*: Terminal SEL1 and SELE are used for distinction between the front multiplex network door ECU LH and RH. Terminal SEL1 and SELE of the front multiplex network door ECU LH are connected.

c. Reconnect the N3 and N4 ECU connectors.
d. Reset the power window regulator motor.




e. Measure the voltage of the connector.
If the result is not as specified, the ECU may have a malfunction.




6. CHECK FRONT MULTIPLEX NETWORK DOOR ECU RH (FRONT PASSENGER SIDE DOOR ECU)

a. Disconnect the M4 ECU connector.

Part 1:

Part 2:

b. Measure the voltage of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the M4 ECU connector.
d. Reset the power window regulator motor.




e. Measure the voltage of the connector.
If the result is not as specified, the ECU may have malfunction.




7. CHECK REAR MULTIPLEX NETWORK DOOR ECU LH (REAR DOOR ECU LH)
a. Disconnect the P2 ECU connector.




b. Measure the voltage and resistance of the wire harness side connector.
