Signal Specification






Signal description

General
All values stated below are measured between each connection in column 1 (Conn. control module) and breakout box connection #B3 unless otherwise noted in column 6 (Other). The control module's connections #A1-#A70 correspond to #A1-#B10 on the breakout box, #B1-#B50 correspond to #B11- #B60 on the breakout box.

Note! It is important to connect the breakout box and check the ground connections before starting to measure.

Hint: If the numbering of the connector is different from the numbering on the breakout box, the connector number is given first, #A61, followed by the breakout box number in brackets, #B1. Example: #A61 (#B1).
