Component Code SID 7, FMI Right Turn Signal | BENDIX BW2849 manual

Fault Isolation Procedures

Component Code: 21

(SID 7, FMI 2)

Right Turn Signal

Overview

This fault code indicates an electrical problem in the right turn signal input. The input from the right turn signal did not match the current operating conditions.

Detection

Starting at key on and throughout the operation, the Central Processing Unit constantly monitors the feedback from the right turn signal.

Fallback

This fault will not allow the Bendix™ VORAD® system to detect objects when the operator is making a right turn.

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:

•Central Processing Unit

•OEM Harness

•Right Turn Signal
