Hello, when that code appears I have always been able to correct your concern by replacing the PCM power relay.

If you don't have your owners manual to find the PCM power relay please let me know and I can provide a location for you. Also if you have more questions please let me know. Don't forget to rate my answer so that I receive credit for assisting you.

This is a diesel? Do you have a multi meter to test the transceiver?

Customer: replied 10 months ago.
but the vehicle is at work could you tell me what to look for so I can test it tomorrow.
Expert:  James replied 10 months ago.

Where the key goes into the steering column there is a transceiver. If you remove the steering column covers you will find four wires attached to it. When you turn the key to the on position you should have 12v on the red wire and a good ground on the black wire. If you have good power and ground then the transceiver is bad and needs to be replaced. That is usually the next issue.
