Ranger 4WD V6-4.0L (2009)
CONNECT the negative battery cable. GO to G7.
No
REPAIR the circuit. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
G7 CHECK FOR CORRECT ABS MODULE OPERATION
-
Disconnect the ABS module connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the ABS module 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 ABS module. 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. CLEAR the DTCs. REPEAT the
network test with the scan tool.

Pinpoint Test H: Intermittent No High Speed Controller Area Network (HS-CAN) Communication,
One Or More Modules Are Not Respond
Communications Network
Pinpoint Test
Pinpoint Test H: Intermittent No High Speed Controller Area Network (HS-CAN) Communication, One Or More Modules Are Not
Responding During Network Test
Normal Operation
The High Speed Controller Area Network (HS-CAN) is used for communication between the PCM, the Smart Junction Box (SJB), the ABS module, the
Restraints Control Module (RCM), the 4X4 control module (if equipped) and the Instrument Cluster (IC). An open circuit VDB04 (WH/BU) (HS-CAN
+) or circuit VDB05 (WH) (HS-CAN -) may cause intermittent or unreliable communication to all modules on the HS-CAN.
In the event that 1 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 H: INTERMITTENT NO HS-CAN COMMUNICATION, ONE OR MORE MODULES ARE NOT RESPONDING
DURING NETWORK TEST
NOTE: Various modules set network DTCs during this test procedure. Clear DTCs from all modules after the diagnostic procedure is completed.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.

H1 CHECK THE DLC PINS FOR DAMAGE
-
Ignition OFF.
-
Disconnect the scan tool cable from the Data Link Connector (DLC).
-
Inspect DLC pins 6 and 14 for damage.
