Pinpoint Test Q : The Side Obstacle Detection Control Module LH (Sod-L) Does Not Respond To The Diagnostic Scan Tool

WARNING: This page is about a different car, the 2019 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

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 SODL communicates with the diagnostic scan tool through the MS-CAN.

Possible Sources
- Fuse
- Wiring, terminals and connector
- SODL
Visual Inspection and Pre-checks
- Verify BJB fuse 23 (7.5A) is OK.

Q1 CHECK FOR DC (DIRECT CURRENT) / DC (DIRECT CURRENT) CONVERTER CONTROL MODULE NETWORK COMMUNICATION
- Ignition ON.
- Using a diagnostic scan tool, perform the network test.
Does the DC/ DC Converter Control Module pass the network test?

Yes GO to Q2

No DIAGNOSE a module communication concern. GO to Pinpoint Test V

Q2 RETRIEVE RECORDED DC (DIRECT CURRENT) / DC (DIRECT CURRENT) CONVERTER CONTROL MODULE DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, perform a DC/ DC Converter Control Module self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?

Yes DIAGNOSE the Diagnostic Trouble Codes (DTCs). REFER to: Direct Current/Direct Current (DC/DC) Converter Control Module .

No GO to Q3

Q3 CHECK THE SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect: SODL C4483.

Ignition ON.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the voltage greater than 11 volts?

Yes

GO to Q4

No	VERIFY BJB fuse 23 (7.5A) 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.

Q4 CHECK THE SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) GROUND CIRCUITS FOR AN OPEN

Ignition OFF.

Measure:

Positive Lead	Measurement / Action	Negative Lead

Are the resistances less than 3 ohms?

Yes

GO to Q5

No	REPAIR the circuit in question.

Q5 CHECK THE MS-CAN (MEDIUM SPEED-CONTROLLER AREA NETWORK) CIRCUITS BETWEEN THE SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) AND THE GWM (GATEWAY MODULE A) FOR AN OPEN

Disconnect: GWM C2431.

Measure:

Positive Lead	Measurement / Action	Negative Lead
C4483-14	Courtesy of FORD MOTOR COMPANY	C2431-23
C4483-15	Courtesy of FORD MOTOR COMPANY	C2431-22

Are the resistances less than 3 ohms?

Yes

GO to Q6

No	REPAIR the circuit in question.

Q6 CHECK FOR CORRECT SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) OPERATION

Ignition OFF.

Disconnect and inspect the SODL 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 SODL 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, 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 SODL. 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.
