• Central electronic module (CEM) terminal #B31 (#31) and left turn signal lamp terminal #1.

For S80 

Take readings between:

• Central electronic module (CEM) terminal #B31 and left front door turn signal lamp terminal #2
• Central electronic module (CEM) terminal #B31 and left turn signal lamp terminal #2.

For the XC90 

Take readings between:
