Pinpoint Test Y : 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 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.

Y1 VERIFY VEHICLE EQUIPMENT - STOP/START
- Verify the vehicle is equipped with stop/start.
Is the vehicle equipped with stop/start?

Yes GO to Y2

No GO to Y4

Y2 CHECK FOR DC (DIRECT CURRENT) / DC (DIRECT CURRENT) CONVERTER CONTROL MODULE COMMUNICATION
- Ignition ON.
- Using the diagnostic scan tool, perform the network test.
Does the DC/ DC Converter Control Module communicate on the network?

Yes GO to Y3

No DIAGNOSE a communication concern. GO to Pinpoint Test AF

Y3 CHECK FOR DC (DIRECT CURRENT) / DC (DIRECT CURRENT) CONVERTER CONTROL MODULE DIAGNOSTIC TROUBLE CODES (DTCS)
- Using the diagnostic scan tool, perform a DC/ DC Converter Control Module self-test.
Are any DC/ DC Converter Control Module Diagnostic Trouble Codes (DTCs) present?

Yes REFER to: Direct Current/Direct Current (DC/DC) Converter Control Module .

No GO to Y4

Y4 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 Y6

No	For vehicles without stop/start, VERIFY the BJB fuse 42 (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. For vehicles with stop/start, GO to Y5

Y5 CHECK THE VOLTAGE STABILITY POWER CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect DC/ DC Converter Control Module C2513 .

Measure:

Positive Lead	Measurement / Action	Negative Lead
C4370-5	Courtesy of FORD MOTOR COMPANY	C2513-5

Is the resistance less than 3 ohms?

Yes

GO to Y6

No	REPAIR the circuit.

Y6 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) GROUND CIRCUIT FOR AN OPEN

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 Y7

No	REPAIR the circuit.

Y7 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

GO to Y8

No	REPAIR the circuit in question.

Y8 CHECK FOR CORRECT SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION

Ignition OFF.

Disconnect and inspect all the SODR 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 SODR 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 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.
