How to diagnose a Ford communication network problem?

To diagnose this network, you will need a high-impedance DVOM and a scanner. First, hook up the DVOM (positive lead) to Pin #7 into the back of the DLC connector, the ground lead attached to the chassis. Then, with the ignition switch OFF or ON, there should be NO voltage on the network.

What kind of network does a Ford vehicle use?

Another handy thing to remember is that newer Ford vehicles are often equipped with more than one network, the second being the ISO 9141 protocol. The ISO 9141 network, is a single-wire, and is often identified as Circuit 70.

What’s the voltage at rest on Ford communication network?

The voltage at “Rest” for Bus + is 0-.2 v. The voltage at “Rest” for Bus – is 5 v. Remember, to get these readings with the DLC and using a DVOM, remember to have the key ‘Off.’ When a message is being sent, the voltages are reversed. You will need a lab scope to see this.
