Fusion FWD V6-3.0L (2009)
INSTALL a new APIM. REFER to Radio, Stereo and Compact Disc. CONNECT all modules. CLEAR the DTCs. REPEAT the network test with the
scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CONNECT all modules. CLEAR
the DTCs. REPEAT the network test with the scan tool.

Pinpoint Test S: Intermittent No Medium Speed Controller Area Network (MS-CAN) Communication, One Or More Modules Are Not
Responding During Network Test
Normal Operation
The Medium Speed Controller Area Network (MS-CAN) uses an unshielded twisted pair cable, circuits VDB06 (GY/OG) and VDB07 (VT/OG).
The following modules communicate on the MS-CAN:
-
Accessory Protocol Interface Module (APIM) (if equipped)
-
Audio Control Module (ACM)
-
Audio Digital Signal Processing (DSP) module (if equipped)
-
Driver Seat Module (DSM) (if equipped)
-
Driver Door Module (DDM) (if equipped)
-
Dual Climate Controlled Seat Module (DCSM) (if equipped)
-
HVAC module (if equipped)
-
Instrument Cluster (IC)
-
Parking Aid Module (PAM) (if equipped)
-
Satellite Digital Audio Receiver System (SDARS) module (if equipped)
-
Smart Junction Box (SJB)
In the event that one of the 2 network circuits (HS-CAN + or HS-CAN -) becomes open to a module on the network, unreliable network communication
to all modules on the network may result.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
PINPOINT TEST S: INTERMITTENT NO MS-CAN COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING
DURING NETWORK TEST
NOTE: Various modules will set network DTCs during this test procedure. Clear the DTCs from all modules after the diagnostic procedure is complete.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
S1 CHECK THE DLC PINS FOR DAMAGE
-
Ignition OFF.
-
Disconnect the scan tool cable from the Data Link Connector (DLC).
-
Inspect DLC pins 3 and 11 for damage.
