Left Side Sensor

Overview

This fault code indicates an electrical failure of the Left Side Sensor.

Detection

Starting at key on and throughout the operation, the Central Processing Unit constantly monitors the feedback from the Left Side Sensor.

Fallback

This fault will not allow the Bendix™ VORAD® system to detect objects on the left side of the vehicle.

Required Tools

•Basic Hand Tools

•Digital Volt/Ohm Meter

•Troubleshooting Guide

•PC-based or Hand-held Diagnostic Tool

Possible Causes

This fault code can be caused by any of the following:

•Wiring Harness

•Left Side Sensor

•Central Processing Unit

•System Conﬁguration
