Malfunction of the sunroof motor assembly or incor-
rect learning of the sunroof fully closed position is
suspected.
.
TROUBLESHOOTING HINTS
• Malfunction of the sunroof motor assembly
• Incorrect learning of the sunroof fully closed posi-
tion
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 (Vehicles with
CAN communication system)
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.
