Pinpoint Test Ac: The Side Obstacle Detection Control Module LH (Sod-L) Does Not Respond To The Diagnostic Scan Tool
- 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 on the MS-CAN.
Possible Sources
- Fuse
- Wiring, terminals and connector
- SODL
Visual Inspection and Pre-checks
- Verify BJB fuse 23 (15A) is OK.
- AC1 VERIFY VEHICLE EQUIPMENT
- Verify the vehicle is equipped with auto stop-start.
Is the vehicle equipped with auto stop-start?
Yes GO to AC2 No GO to AC3 - AC2 CHECK NETWORK COMMUNICATION
- Using a diagnostic scan tool, perform the network test.
Did the DCDC pass the network test?
Yes GO to AC3 No GO to Pinpoint Test I - AC3 CHECK THE SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) VOLTAGE SUPPLY CIRCUITS FOR AN OPEN
- Ignition OFF.
- Disconnect: SODL C4369.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C4369-5 Ground
Is the voltage greater than 11 volts?
Yes GO to AC4 No VERIFY the BJB fuse 23 (15A) 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. - AC4 CHECK THE SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) GROUND CIRCUIT FOR AN OPEN
- Ignition OFF.
- Measure:
Positive Lead Measurement / Action Negative Lead C4369-8 Ground
Is the resistance less than 3 ohms?
Yes GO to AC5 No REPAIR the circuit. - AC5 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.
Are the resistances less than 3 ohms?
Yes CONNECT the GWM, GO to AC6 No REPAIR the circuit in question. - AC6 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, General Service Bulletin (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.
