below.

• Ignition switch (IG1)

• Key reminder switch

• Door switches

• Liftgate latch switch

• Front door lock actuator

.

TECHNICAL DESCRIPTION (COMMENT)

If this does not work normally, the above switch input 
circuit(s), rear dome light, or ETACS-ECU may have 
a problem.

.

PROBABLE CAUSES

• Malfunction of the key reminder switch

• Malfunction of door switch

• Malfunction of liftgate latch switch

• Malfunction of the front door lock actuator (RH)

• Malfunction of rear dome light

• Malfunction of the ETACS-ECU

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle 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. Front dome light operation check
Check that the front dome light illuminates and extinguishes 
normally.
