PINPOINT TEST V : The SOD-R Does Not Respond To The Diagnostic Scan Tool
WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Failure to disconnect the battery when instructed will result in false resistance readings. Refer to
Battery, Mounting and Cables
.
- V1 CHECK THE SOD-R VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: SOD-R C4370 .
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C4370-2 Ground
Are the voltages 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-R GROUND CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: Negative Battery Cable.
Are the resistances less than 3 ohms?
Yes GO to V3. No REPAIR the circuit in question. - V3 CHECK THE MS-CAN CIRCUITS BETWEEN THE SOD-R AND THE DLC FOR AN OPEN
Are the resistances less than 3 ohms?
Yes CONNECT the negative battery cable. GO to V4. No REPAIR the circuit in question. CONNECT the negative battery cable. - V4 CHECK FOR CORRECT SOD-R OPERATION
- Ignition OFF.
- Disconnect and inspect the SOD-R connector and related in-line connectors.
- 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-R connector and related in-line connectors. Make sure they seat and latch correctly.
- Operate the system and verify the concern is still present.
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-R. 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.
