Mariner 4WD V6-3.0L (2010)
INSTALL a new High Voltage Traction Battery (HVTB). REFER to Hybrid Drive Systems. 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.
-------------------------------------------------
T46 CHECK FOR CORRECT ACCM OPERATION
NOTE: Do not disconnect the high-voltage cables or connectors in the following step.
-
Disconnect the ACCM low voltage connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the ACCM low voltage connector and make sure it seats correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new High Voltage Traction Battery (HVTB). REFER to Hybrid Drive Systems. 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.

Pinpoint Tests
Pinpoint Test U: Intermittent No Medium Speed Controller Area Network (MS-CAN) Communication, Communication Can Be Intermittently
Established
Normal Operation
The Medium Speed Controller Area Network (MS-CAN) uses an unshielded twisted pair cable. In the event that 1 of the 2 network circuits (MS-CAN +
or MS-CAN -) becomes open to a module on the network, unreliable network communication to all modules on the network may result.
The following modules communicate with the scan tool using the MS-CAN:
-
Audio Control Module (ACM)
-
Accessory Protocol Interface Module (APIM) (if equipped)
-
Front Controls Interface Module (FCIM) (if equipped)
-
Front Display Interface Module (FDIM)
-
Global Positioning System Module (GPSM) (if equipped)
-
HVAC module
-
Instrument Cluster (IC)
-
Smart Junction Box (SJB)
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
PINPOINT TEST U: INTERMITTENT NO MS-CAN COMMUNICATION, COMMUNICATION CAN BE INTERMITTENTLY
ESTABLISHED
NOTE: Various modules set network DTCs during this test procedure. Clear DTCs from all modules after the diagnostic procedure is completed.
