DIAGNOSIS

Required Special Tool:

• MB991223: Harness Set

STEP 1. Check the fusible link (4) line of power supply
circuit to the sunroof motor assembly. Test at sunroof
motor assembly connector F-02.
(1) Disconnect sunroof motor assembly connector F-02 and

measure the voltage available at the wiring harness side of
the connector.

(2) Measure the voltage between terminal 1 and ground.

• The voltage should be approximately 12 volts (battery

positive voltage).

Q: Is the measured voltage approximately 12 volts (battery

positive voltage)?
YES : Go to Step 4.
NO : Go to Step 2.

STEP 2. Check the sunroof motor assembly connector F-
02 for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is sunroof motor assembly connector F-02 in good

condition?
