Step 2. Check the power window sub switch.
Check that each power window works by means of
the respective power window sub switch when the
power window lock switch is turned off.

Q: Is the check result normal?

YES :

Go to Step 3.

The trouble can be an intermittent

malfunction (Refer to GROUP 00

− How to

use Troubleshooting/inspection Service
Points

− How to Cope with Intermittent

Malfunction

P.00-13

).

NO :

Replace the power window main switch.

Inspection Procedure D-5: The power window timer function does not work normally.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
