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.
