power window main switch connector terminal
Nos.8, 9, 10 and 12 to F-10 power window motor
(front: LH) connector terminal Nos.6, 2, 4 and 5.

• Check the input and output lines to the revolution

detection sensor for open or short circuit.

Q: Is the check result normal?

YES :

Go to Step 6.

NO :

Repair the wiring harness.

Step 6. Retest the system.

After the power window main switch is replaced,
