SIMPLIFIED WIRING SYSTEM (SWS)

.

CIRCUIT OPERATION
The ETACS-ECU receives a signal through the 
sunroof motor assembly via the SWS communication 
line from the sunroof switch, and sends a signal to 
the data link connector.

.

TECHNICAL DESCRIPTION (COMMENT)
If the SWS communication line between the sunroof 
motor assembly and the ETACS-ECU is defective, 
the ETACS-ECU cannot identify the input signal from 
the sunroof switch even if the sunroof is normal.

.

TROUBLESHOOTING HINTS

• The sunroof switch may be defective

• The sunroof motor assembly may be defective

• The ETACS-ECU may be defective

• The wiring harness or connectors may have 

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

• MB991223: Harness Set

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B
