Step 13. Resistance measurement at the F-05
power window main switch connector.

(1) Disconnect the connector, and measure at the

wiring harness side.

(2) Resistance between F-05 power window main

switch connector terminal No.2 and body earth.

OK: 2

Ω or less

Q: Is the check result normal?

YES :

Go to Step 15.

NO :

Go to Step 14.

Step 14. Check the wiring harness between F-05
power window main switch connector terminal
No.2 and body earth.

NOTE:

Prior to the wiring harness inspection, check
intermediate connectors C-14 <RH drive vehicles>,
C-27 <LH drive vehicles>, and repair if necessary.

• Check the earth wires for open circuit.

Step 17. ECU check by using the SWS monitor.

Check that the power supply and earth lines to the
power window main switch (power window module)
and the SWS communication lines are normal.

• Ignition switch: ON

ECUS TO BE CHECKED

• P/W MODULE

OK: "OK" is displayed on the "P/W
MODULE" menu.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00
