.

PROBABLE CAUSES

• Malfunction of the sunroof motor assembly

• Malfunction of the sunroof switch

• Damaged wiring harness and connectors

DIAGNOSTIC PROCEDURE

STEP 1. Check sunroof switch connector D-03 and sunroof
motor assembly D-04 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Are sunroof switch connector D-03 and sunroof motor

assembly D-04 in good condition?
YES : Go to Step 2.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Check that the sunroof works normally.

STEP 2. Check the wiring harness between sunroof switch
connector D-03 (terminals No. 3, 5, 6) and sunroof motor
assembly connector D-04 (terminals No. 4, 5, 10).

• Check the power supply line for open circuit and short cir-

cuit.

Q: Is the wiring harness between sunroof switch connector

D-03 (terminal 3, 5, 6) and sunroof motor assembly
connector D-04 (terminal No. 4, 5, 10) in good
condition?
YES : Go to Step 3.
NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Check that
the sunroof works normally.
