Apparatus and method for identifying electrical faults
First Claim
1. An apparatus for identifying an electrical fault in an electrical system, the apparatus comprising:
- an electronic service tool configured to instruct an electronic control module to disable an enable condition and modify a trip condition set by the electronic control module, receive electrical system data from the electronic control module as a user wiggles a component of the electrical system, and communicate a fault code to the user when the electrical system data fulfills the modified trip condition.

Abstract
A method of identifying an electrical fault in an electrical system may include coupling an electronic service tool to an electronic control module. The method may also include instructing the electronic control module to disable an enable condition and modify a trip condition set by the electronic control module. The method may further include monitoring the electrical system as a user wiggles a component of the electrical system. The method may further include providing the electronic control module with electrical system data, and generating a fault code when the electrical system data fulfills the modified trip condition. The method may further include communicating the fault code to the user.

17. A method of reconfiguring an on-board diagnostics system to identify electrical faults in an electrical system of a machine, the method comprising:
-
switching the on-board diagnostics system from a normal test mode into a wiggle test mode using an electronic service tool; wherein the normal test mode, the on-board diagnostics system sets an enable condition and a trip condition to identify a hard fault in the electrical system; wherein when the electronic service tool switches the on-board diagnostics system into the wiggle test mode, the enable condition is disabled and the trip condition is modified to identify an intermittent fault in the electrical system. - View Dependent Claims (18, 19, 20)
