Pinpoint Test Aa : The SODR (Side Obstacle Detection Control Module RH) Does Not Respond To The Diagnostic Scan Tool
WARNING: This page is about a different car, the 2020 Lincoln Corsair. 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 SODR communicates on the MS-CAN.
Possible Sources
- Fuse
- Wiring, terminals and connector
- SODR
Visual Inspection and Pre-checks
- Verify BJB fuse 25 (10A) is OK.
- AA1 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: SODR C4370.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C4370-5 Ground
Is the voltage greater than 11 volts?
Yes GO to AA2 No VERIFY BJB fuse 25 (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. - AA2 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) GROUND CIRCUITS FOR AN OPEN
- Ignition OFF.
Are the resistances less than 3 ohms?
Yes GO to AA3 No REPAIR the circuit in question. - AA3 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.
Are the resistances less than 3 ohms?
Yes GO to AA4 No REPAIR the circuit in question. - AA4 CHECK FOR CORRECT SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION
- Ignition OFF.
- Disconnect and inspect 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, 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.
