Fusion AWD V6-3.0L (2009)
Circuits VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the DCSM. Voltage for the DCSM is
provided by circuits SBB11 (BU/RD) and SBB12 (GN/RD). Circuit GD139 (BK/YE) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
DCSM
PINPOINT TEST P: PINPOINT TEST P: THE DCSM DOES NOT RESPOND TO THE SCAN TOOL
WARNING: Remove restraint system diagnostic tools from the vehicle prior to road testing. If tools are not removed, the supplemental
restraint system (SRS) device may not deploy in a crash. Failure to follow this instruction may result in serious personal injury or death in a
crash and possibly violate vehicle safety standards.
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: If a seat equipped with a Supplemental Restraint System (SRS) component is being serviced, the SRS must be depowered. Refer to Air Bag
Systems.
NOTE: The air bag warning lamp illuminates when the Restraints Control Module (RCM) fuse is removed and the ignition switch is ON. This is normal
operation and does not indicate a SRS fault.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.

P1 VERIFY VEHICLE EQUIPMENT - SEAT SIDE AIR BAGS
-
Inspect the vehicle for seat side air bags.
-
Is the vehicle equipped with seat side air bags?
Yes
GO to P2.
No
GO to P3.
-------------------------------------------------
P2 CHECK THE DCSM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
-
Ignition OFF.
-
For vehicles with seat side air bags, carry out the following:
-
Depower the SRS. Refer to Air Bag Systems.
-
Disconnect the driver seat side air bag module C3226.
-
Connect the restraint system diagnostic tool (418-133) to the driver seat side air bag module C3226.
-
Disconnect the passenger seat side air bag module C3227.
-
Connect the restraint system diagnostic tool (418-133) to the passenger seat side air bag module C3227.
-
Connect the negative battery cable.
-
Disconnect: DCSM C3305a.
-
Ignition ON.
-
Measure the voltage between the DCSM C3305a-E, circuit SBB11 (BU/RD) harness side and ground; and between the DCSM C3305a-F, circuit
SBB12 (GN/RD) harness side and ground.
