id091800809500

1. Remove the following parts:

(1) Glove compartment (See GLOVE COMPARTMENT REMOVAL/INSTALLATION.)

(2) Upper panel (See UPPER PANEL REMOVAL/INSTALLATION.)

(3) Shift panel (See SHIFT PANEL REMOVAL/INSTALLATION.)

(4) Center panel lower (See CENTER PANEL LOWER REMOVAL/INSTALLATION.)

(5) Decoration panel (See DECORATION PANEL REMOVAL/INSTALLATION.)

(6) Rear console (See REAR CONSOLE REMOVAL/INSTALLATION.)

2. Remove the auto light/wiper control module with the connector connected.

3. Measure the voltage at each terminal is as indicated in the Terminal Voltage Lists.

• If the voltage is not as specified in the Terminal Voltage Lists, inspect the parts under “Inspection item (s)”.

― If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the auto light/wiper control module.
