Caution! Avoid touching control module connector pins and corresponding cable harness connectors. There is a risk of electrostatic discharge, which could damage the control module. Relieve any charge on yourself and the tools to be used by holding the metal part of the tool and touching part of the body just before starting work.

General information
Visually check the connectors to ensure that the male and female terminals are not damaged and that the cables for the female halves are properly connected.
The breakout box is designed to facilitate reading off control module output and input signals when the control module is connected as well as resistance of cables and components when the control module is disconnected. Using a breakout box reduces the risk of unintentionally short-circuiting cables or damaging connector pins.
