Q: Is the wiring harness between sunroof switch connector
D-05 (terminal 4) and sunroof motor assembly
connector D-06 (terminal No. 1) in good condition?
YES : No action is necessary and testing is complete.
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.
STEP 8. Check sunroof motor assembly connector D-06
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is sunroof motor assembly connector D-06 in good
condition?
YES : Go to Step 9.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. Check that the sunroof works normally.
STEP 9. Check the ground circuit to the sunroof motor
assembly. Measure the resistance at sunroof motor
assembly connector D-06.
(1) Disconnect sunroof motor assembly connector D-06 and
measure the resistance available at the wiring harness side
of the connector.
(2) Measure the resistance value between terminal 2 and
ground.
• The resistance should be 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 11.
NO : Go to Step 10.
STEP 10. Check the wiring harness between sunroof motor
assembly connector D-06 (terminal 2) and ground.
Q: Is the wiring harness between sunroof motor assembly
connector D-06 (terminal 2) and ground in good
condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the

nals pushed back in the connector
DIAGNOSTIC PROCEDURE
Required Special Tools:
• MB992006: Extra fine probe
• MB991223: Harness set
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: Vehicles Communication Interface (V.C.I.)
• MB991827: M.U.T.-III USB Cable
• MB991910: M.U.T.-III Main Harness A
STEP 1. Using scan tool MB991958, read the diagnostic
trouble code.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect
scan tool (M.U.T.-III)
(2) Turn the ignition switch to the "ON" position.
