You can set the rotary dial of the DMM to the Ohm position, disconnect the power feed (i.e. fuse, control module) from the suspect circuit, disconnect the load, press the MIN MAX button on the DMM, connect one lead of the DMM to one end of the circuit to be tested and connect the other lead of the DMM to the other end of the circuit, then if the DMM displays low or no resistance and a tone is heard, the circuit has good continuity.
