WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: TERMINALS OF ECU

1. CHECK POWER WINDOW REGULATOR MASTER SWITCH (FOR DOUBLE CAB):





(a) Disconnect the P9 power window regulator master switch connector.

(b) Measure the voltage and resistance of each of the wire harness side connector terminals.





(c) If the result is not as specified, there may be a malfunction on the wire harness side.

(d) Reconnect the power window regulator master switch connector.

(e) Measure the voltage of the connector terminals.





(f) If the result is not as specified, the switch may have a malfunction.

(g) Check the illumination.

(1) When the ignition switch is turned to ON from OFF with the connector connected, check that the illumination (YELLOW) AUTO lights up.

3. CHECK DRIVER SIDE J/B ASSEMBLY (MULTIPLEX NETWORK BODY ECU)





(a) Disconnect the 1A, 1C, 1F, 1H, 1I and 1K driver side J/B connectors.

(b) Measure the voltage and resistance between each terminal of the wire harness side connectors and body ground.





(c) If the result is not as specified, there may be a malfunction on the wire harness side.

(d) Reconnect the driver side J/B connectors.

(e) Measure the voltage between each terminal of the connector and body ground.





(f) If the result is not as specified, the driver side J/B assembly (multiplex network body ECU) may have a malfunction.
