Signal specification (2002-2004)
General
All the values listed below are between the respective terminal in column 2 and terminal #36 (power ground) unless otherwise stated in column 6 (Other). Control module terminals #A1-#A60 correspond to terminals #A1-#A60 on the breakout box, terminals #A61-#A70 correspond to terminals #B1-#B10 on the breakout box and terminals #B1-#B50 correspond to terminals #B11-#B60 on the breakout box.
NOTE:
It is important to connect the breakout box and check the ground terminals before taking readings.
HINT: If the numbering of the connector is different from the numbering on the breakout box, the connector number is given first, terminal #A61, followed by the breakout box number in parenthesis, (terminal #B1).
HINT: Example: #A61 (#B1)
