The 2 120 ohm resistors in parallel will give you a ~60 ohms reading between the DLC pins if the circuit is fully intact and both terminating resistors are in play. ~120 ohms between those pins indicates that one of the terminating resistors is no longer present (ie. a break somewhere along the line). A complete open circuit from a meter perspective will show as infinite resistance (ex. OL display on the meter. True 0 resistance indicates full continuity. Between the canbus pins of the DLC, a 0 resistance indicates a dead short between the 2 lines.
