PINPOINT TEST V : The SOD-L Does Not Respond To The Scan Tool

NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. REFER to Battery, Mounting and Cables

V1 CHECK THE SOD-L VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the voltage greater than 11 volts?

Yes	GO to V2.
No	VERIFY the BCM fuse 34 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify the possible causes of the circuit short.

V2 CHECK THE SOD-L GROUND CIRCUIT FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead

Is the resistance less than 3 ohms?

Yes	GO to V3.
No	REPAIR the circuit.

V3 CHECK THE MS-CAN CIRCUITS BETWEEN THE SOD-L AND THE DLC FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
C4369-3	Courtesy of FORD MOTOR COMPANY	C251-3
C4369-4	Courtesy of FORD MOTOR COMPANY	C251-11

Are the resistances less than 3 ohms?

Yes	CONNECT the negative battery cable. GO to V4.
No	REPAIR the circuit in question.

V4 CHECK FOR CORRECT SOD-L OPERATION

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

Reconnect the SOD-L connector and related in-line connectors. Make sure they seat and latch correctly.

Is the concern still present?

Yes	CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs address this concern, INSTALL a new SOD-L. REFER to Side and Rear Vision .
No	The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
