Diagnostic Overview

The Side Obstacle Detection Control Module - Left (SOD-L) Does Not Respond To The Scan Tool

Refer to Wiring Diagram Set 14 for schematic and connector information Electrical Diagrams.

Refer to Wiring Diagram Set 136 for schematic and connector information Electrical Diagrams.

Normal Operation and Fault Conditions

The SOD-L (Side Obstacle Detection Control Module - Left) communicates with the scan tool through the MS-CAN (Medium Speed Controller Area Network).

Visual Inspection and Diagnostic Pre-checks

Verify BCM (Body Control Module) fuse 34 (10A) is OK.

Pinpoint Test

1. CHECK THE SOD-L (Side Obstacle Detection Control Module - Left) VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

1. Ignition OFF.

2. Disconnect: SOD-L (Side Obstacle Detection Control Module - Left).

3. Ignition ON.

4. Measure:





Is the voltage greater than 11 volts?






2. CHECK THE SOD-L (Side Obstacle Detection Control Module - Left) GROUND CIRCUIT FOR AN OPEN

1. Ignition OFF.

2. Measure:





Is the resistance less than 3 ohms?






3. CHECK THE MS-CAN (Medium Speed Controller Area Network) CIRCUITS BETWEEN THE SOD-L (Side Obstacle Detection Control Module - Left) AND THE DLC (Data Link Connector) FOR AN OPEN

1. Measure:





Are the resistances less than 3 ohms?






4. CHECK FOR CORRECT SOD-L (Side Obstacle Detection Control Module - Left) OPERATION

1. Ignition OFF.

2. Disconnect and inspect the SOD-L (Side Obstacle Detection Control Module - Left) connector.

3. Repair:

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

4. Reconnect the SOD-L (Side Obstacle Detection Control Module - Left) connector. Make sure it seats and latches correctly.

5. Operate the system and verify the concern is still present.

Is the concern still present?
