Need some help to find an open circuit

There appears to be an open circuit in the DSC/RSC system wiring. Have looked at the workshop manual but can't clearly understand the instructions shown in the attachment.
If I want to test the continuity in LR speed sensor, should I connect one of the multimeter leads to terminal F and the other to terminal B?
To do an ohm reading on the LR ABS sensor, should I connect the leads to terminals F and I (i) ?

Besides disconnecting the battery, any other precautions I need to take?

I spoke to an EE about this. He told me the first thing he would do is swap speed sensor connectors for RR and LR. That would isolate the sensor/connector assy that is at fault.
As far as checking resistance, try checking the suspected bad sensor connector's resistance from F to I (if checking the LR wheel speed sensor, for example). If a wire or wire-to-pin connection is broken there will be no resistance reading. (O.L will be displayed).
