When this fails, the oracle looks at . A healthy CAN bus system should read 60 ohms between CAN High and CAN Low (due to two 120-ohm terminating resistors in parallel). If you see 120 ohms, one resistor is missing (open circuit). If you see 0 ohms, the bus is shorted.

Electricity is lazy. It will take the path of least resistance. If a ground wire is corroded, the starter motor will try to ground through the throttle cable, the brake line, or the wheel bearing—destroying them. When this fails, the oracle looks at
The oracle does not guess. The oracle tests, measures, and verifies. If you see 0 ohms, the bus is shorted
