Escape 2WD V6-3.0L (2009)
-
pushed-out pins
-
Connect all the RCM 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 RCM. 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 F: The Occupant Classification System Module (OCSM) Does Not Respond To The Scan Tool
Refer to Wiring Diagram Set 14 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Module Communications Network for schematic and connector
information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Refer to Wiring Diagram Set 46 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Supplemental Restraint Systems for schematic and connector
information. See: Diagrams/Electrical Diagrams/Diagrams By Number
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 HS-CAN connection to the OCSM. Voltage for the OCSM is
provided by circuit CBP46 (WH/BU) and circuit GD183 (BK/WH) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
OCSM
PINPOINT TEST F: THE OCSM DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.

F1 CHECK THE OCSM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Disconnect: OCSM C3285.
-
Ignition OFF.
-
Ignition ON.
-
Measure the voltage between the OCSM C3285-1, circuit CBP46 (WH/BU), harness side and ground.
