Pinpoint Test H: The SODL (Side Obstacle Detection Control Module LH) Does Not Respond To Diagnostic Scan Tool

Refer to VEHICLE EMERGENCY MESSAGING SYSTEM for schematic and connector information.
Normal Operation and Fault Conditions

The SODL communicates with the IPMA through a private CAN bus.

Possible Sources
- Wiring, terminals and connector
- SODL

H1 CHECK FOR IPMA (IMAGE PROCESSING MODULE A) NETWORK CONNECTION
- Ignition ON.
- Using a diagnostic scan tool, carry out the network test.
Does the IPMA pass the network test?

Yes GO to H2

No DIAGNOSE an IPMA communication concern. REFER to: Controller Area Network (CAN) Module Communications Network .

H2 CHECK THE SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) VOLTAGE SUPPLY CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect: SODL C4733

Ignition ON.

H9 CHECK FOR CORRECT SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) OPERATION

Ignition OFF.

Disconnect and inspect the SODL connector and related in-line connectors.

Repair:
- Corrosion (clean module pins or install new connectors or terminals)
- Damaged or bent pins (install new terminals or pins)
- Pushed-out pins (install new pins as necessary)

Reconnect the SODL connector and related in-line connectors. Make sure all connectors seat and latch 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 SODL. REFER to: Side Obstacle Detection Control Module (SODCM) If the concern is still present, GO to H10

No	The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.

H10 CHECK FOR CORRECT IPMA (IMAGE PROCESSING MODULE A) OPERATION

Disconnect and inspect all the IPMA connectors.

Repair:
- Corrosion (clean module pins or install new connectors or terminals)
- Damaged or bent pins (install new terminals or pins)
- Pushed-out pins (install new pins as necessary)

Reconnect the IPMA connectors. Make sure they seat and latch 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 IPMA. REFER to: Image Processing Module A (IPMA) .

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.
