Pinpoint Test X : The Side Obstacle Detection Control Module RH (Sod-R) Does Not Respond To The Diagnostic Scan Tool

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

X1 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) VOLTAGE SUPPLY CIRCUITS FOR AN OPEN

Ignition OFF.

Disconnect: SODR C4484 (with LED rear lamps) or C461 (without LED rear lamps).

Ignition ON.

Measure:

With LED rear lamps

Positive Lead	Measurement / Action	Negative Lead
Refer to C4484-5	Courtesy of FORD MOTOR COMPANY	Ground

Without LED rear lamps

Positive Lead	Measurement / Action	Negative Lead
Refer to C461-3	Courtesy of FORD MOTOR COMPANY	Ground

Is the voltage greater than 11 volts?

Yes

GO to X2

No	VERIFY the BJB fuse 34 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to OEM Electrical Wiring Diagram Introduction to identify the possible causes of the circuit short.

X2 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) GROUND CIRCUIT FOR AN OPEN

Ignition OFF.

Measure:

With LED rear lamps

Positive Lead	Measurement / Action	Negative Lead
Refer to C4484-9	Courtesy of FORD MOTOR COMPANY	Ground

Without LED rear lamps

Positive Lead	Measurement / Action	Negative Lead
Refer to C461-6	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance less than 3 ohms?

Yes

GO to X3

No	REPAIR the circuit.

X3 CHECK THE MS-CAN (MEDIUM SPEED-CONTROLLER AREA NETWORK) CIRCUITS BETWEEN THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) AND THE GWM (GATEWAY MODULE A) FOR AN OPEN

Disconnect: GWM C2431

Measure:

With LED rear lamps

Positive Lead	Measurement / Action	Negative Lead
Refer to C4484-6	Courtesy of FORD MOTOR COMPANY	Refer to C2431-23
Refer to C4484-12	Courtesy of FORD MOTOR COMPANY	Refer to C2431-22

Without LED rear lamps

Positive Lead	Measurement / Action	Negative Lead
Refer to C461-4	Courtesy of FORD MOTOR COMPANY	Refer to C2431-23
C491-8	Courtesy of FORD MOTOR COMPANY	Refer to C2431-22

Are the resistances less than 3 ohms?

Yes

GO to X4

No	REPAIR the circuit in question.

X4 CHECK FOR CORRECT SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION

Ignition OFF.

Disconnect and inspect the SODR connector 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 SODR connector 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 SODR. REFER to: Side Obstacle Detection Control Module .

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.
