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 the control module input and output signals when the control module is connected; and the cable and component resistance when the control module is disconnected. The use of a breakout box reduces the risk of accidental short-circuits and damage to the connector pins.
