Control module connector, terminal #1-#42
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
All values given below are between the relevant terminal in column 1 and terminal #1 (power and signal ground), unless otherwise indicated in brackets.
NOTE:
It is important to connect the breakout box and check ground terminals before taking readings.
