The breakout box is designed to facilitate reading off the control module input and output signals when the steering wheel module (SWM) 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-circuited cables and damage to the connector pins.
Disconnect the breakout box in reverse order.

Note! Note! Before the control module can be checked and readings taken, the removed fuses must first be installed
