Overview
Required Tools
The pretest verifies the basic electrical inputs before testing
individual circuits.

•
Troubleshooting Guide
Possible Causes
This pretest can be used for any of the following:
•
Corroded Power Contacts
•
Blown Fuse
•
Wiring Harness
•
Low Batteries
Electrical Pretest
There is no detection process specifically for the basic electrical
supply. However, failures of this type are generally detected by the
Bendix™ VORAD® system or the driver as some other type of fault
code or symptom.
