Pinpoint Test F : The SCCM (Steering Column Control Module) Does Not Respond To The Diagnostic Scan Tool

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

F1 CHECK THE HS-CAN2 (HIGH SPEED-CONTROLLER AREA NETWORK 2) TERMINATION RESISTANCE

Ignition OFF.

Disconnect the diagnostic scan tool cable from the DLC.

Is the resistance between 54 and 66 ohms?

Yes

GO to F3

GO to F2

F2 CHECK THE HS-CAN2 (HIGH SPEED-CONTROLLER AREA NETWORK 2) CIRCUITS BETWEEN THE SCCM (STEERING COLUMN CONTROL MODULE) AND THE DLC (DATA LINK CONNECTOR) FOR AN OPEN

Disconnect SCCM C226A

Measure:

Positive Lead	Measurement / Action	Negative Lead

C226A-4	Courtesy of FORD MOTOR COMPANY	C251-11

Are the resistances less than 3 ohms?

Yes

GO to F5

No	REPAIR the circuit in question.

F3 CHECK THE SCCM (STEERING COLUMN CONTROL MODULE) VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C226A-7	Courtesy of FORD MOTOR COMPANY	Ground

Is the voltage greater than 11 volts?

Yes

GO to F4

No	VERIFY the BCM fuse 13 (7.5A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM Wiring Diagrams to identify the possible causes of the circuit short.

F4 CHECK THE SCCM (STEERING COLUMN CONTROL MODULE) GROUND CIRCUIT FOR AN OPEN

Ignition OFF.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C226A-5	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance less than 3 ohms?

Yes

GO to F5

No	REPAIR the circuit.

F5 CHECK FOR CORRECT SCCM (STEERING COLUMN CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all the SCCM connectors and related in-line connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the SCCM connectors and related in-line connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes

CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new SCCM. Without adaptive steering, REFER to: Steering Column Control Module (SCCM) . With adaptive steering, REFER to: Steering Column Control Module (SCCM) - Vehicles With: Adaptive Steering .

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
