Checking for contact resistance and oxidation

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.

The cause of the diagnostic trouble code (DTC) was poor contact in the control module connector or the fuse holder for fuse no. 12 (50 A).
Check the control module connector and the fuse holder. Check for contact resistance and oxidation.
