Overview

The Side Object Detection (SOD) Driver Display Unit illuminates both the red and yellow lamps to indicate a system Diagnostic Trouble

Code (DTC).

Diagnostic Trouble Code (DTC) Detection

Whenever the SOD Driver Display looses communications with the side sensor, or if the sensor reports an internal failure, the display will

illuminate both the red and yellow lamps.

Symptom

The Side Object Detection system will fail to detect objects in its detection zone.

Possible Causes

 • BrokenorshortedwirebetweentheSODdisplayandtheSODsensor

 • MalfunctioningSideSensor

Repair Procedure

Condition Steps to Perform

Red and Yellow ON 1. Disconnect the Driver Display and the Side Sensor from the interconnect harness.

2. Test the resistance between Pin-3 of the Driver Display harness connector and chassis

ground.

   a. Ifgreaterthan100Kohms,continuetonextstep.

   b. Iflessthan100Kohms,testfailed.Repairharness.

3. Test resistance between Pin-3 of the Driver Display harness connector and Pin-3 of the

Side Sensor harness connector.

a. If less than 0.9 ohms, continue to next step.

b. If greater than 0.9 ohms, test failed. Repair harness.

4. Test complete. Replace Side Sensor.
