Ranger 4WD V6-4.0L (2009)
-
Are the resistances less than 5 ohms?
Yes
CONNECT the negative battery cable. GO to A7.
No
REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
A7 CHECK FOR CORRECT PCM OPERATION
-
Disconnect all the PCM connectors.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect all the PCM connectors and make sure they seat correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new PCM. 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.

Normal Operation
The Occupant Classification System Module (OCSM) communicates with the scan tool through the High Speed Controller Area Network (HS-CAN).
Circuits VDB04 (WH/BU) (HS-CAN +) and VDB05 (WH) (HS-CAN -) provide the network connection to the OCSM. Voltage for the OCSM is
provided by circuit CBP08 (GY/YE). Circuit GD174 (BK/WH) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
