• 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.

front power window motor (LH) connector E-16 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Are power window main switch connector E-19, front 

power window motor (LH) connector E-16 in good 
condition?
YES : Go to Step 4.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the power window works

STEP 4. Check the wiring harness between power window 
main switch connector E-19 (terminals 2, 6) and front 
power window motor (LH) connector E-16 (terminals 4, 1). 

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

cuit.

Q: Is the wiring harness between power window main 

switch connector E-19 (terminals 2, 6) and front power 
window motor (LH) connector E-16 (terminals 4, 1) in 
good condition?
YES : Go to Step 5.
NO :  The wiring harness may be damaged or the 

connector(s) may have loose, corroded or damaged
