Taurus AWD V6-3.5L (2009)
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
network test with the scan tool.

Normal Operation
The Driver Seat Module (DSM) communicates with the scan tool through the Medium Speed Controller Area Network (MS-CAN). Circuits VDB06
(GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the DSM. The DSM shares the MS-CAN with the Smart
Junction Box (SJB), the Accessory Protocol Interface Module (APIM), the HVAC module, the Audio Control Module (ACM), the Liftgate/Trunk
Module (LTM), the Rear Entertainment Module (RETM), the Satellite Digital Audio Receiver System (SDARS) module, and the Instrument Cluster
(IC). Voltage and ground for the DSM is provided by circuits SBB32 (VT/RD) and SBP12 (GN/RD). Circuits GD147 (BK/VT) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
DSM
PINPOINT TEST J: THE DSM DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.

J1 CHECK THE DSM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
Disconnect: DSM C341a.
-
Disconnect: DSM C341b.
-
Measure the voltage between the DSM C341a-1, circuit SBB32 (VT/RD), harness side and ground.
-
Measure the voltage between the DSM C341b-1, circuit SBP12 (GN/RD), harness side and ground.
-
Are the voltages greater than 10 volts?
