REPAIR the circuit in question. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool.
-------------------------------------------------
E5 CHECK FOR CORRECT RCM OPERATION
-
Disconnect all the RCM connectors.
-
Check for:
-
corrosion
-
damaged pins
-
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. REFER to Restraint Systems. 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 Tests
Pinpoint Test F: The Occupant Classification System Module (OCSM) Does Not Respond To The Scan Tool
Refer to Wiring Diagram Set 14 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Module Communications Network for schematic and connector
information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Refer to Wiring Diagram Set 46 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Supplemental Restraint System 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).
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
WARNING: Never disassemble or tamper with safety belt buckle/retractor pretensioners or adaptive load limiting retractors or probe the
electrical connectors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load
limiting retractors which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
