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

Refer to Module Communications Network for schematic and connector information. Refer to Vehicle Emergency Messaging System for schematic and connector information.
Normal Operation and Fault Conditions

The SODR communicates on the MS-CAN.

Possible Sources
- Fuse
- Wiring, terminals and connector
- SODR
Visual Inspection and Pre-checks
- Verify BJB fuse 23 (15A) is OK.

AD1 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) VOLTAGE SUPPLY CIRCUITS FOR AN OPEN

Ignition OFF.

Disconnect: SODR C4370.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the voltage greater than 11 volts?

Yes

GO to AD2

No	VERIFY the BJB fuse 23 (15A) 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.

AD2 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) GROUND CIRCUIT FOR AN OPEN

Ignition OFF.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C4370-3	Courtesy of FORD MOTOR COMPANY	Ground
C4370-8	Courtesy of FORD MOTOR COMPANY	Ground

Are the resistances less than 3 ohms?

Yes

GO to AD3

No	REPAIR the circuit.

AD3 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:

Positive Lead	Measurement / Action	Negative Lead
C4370-6	Courtesy of FORD MOTOR COMPANY	C2431-23
C4370-7	Courtesy of FORD MOTOR COMPANY	C2431-22

Are the resistances less than 3 ohms?

Yes	CONNECT the GWM, GO to AD4

No	REPAIR the circuit in question.

AD4 CHECK FOR CORRECT SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION

Ignition OFF.

Disconnect and inspect all the SODR connector.

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. Make sure it seats and latches correctly.

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

Is the concern still present?

Yes

CHECK OASIS for any applicable service articles: TSB, General Service Bulletin (GSB), SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles 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.
