Codes E350 OBD1

Hi,

First, take a look through this link. It explains how to retrieve codes which you have already done. Also, there is a list of codes with their descriptions.

Looking through the codes you have, my biggest concern is the overcharging. That can damage several things and cause a lot of sensors and electrical components to act oddly. So, the first thing I would like you to do is check the alternator output to confirm the code is accurate. Here is a link that explains how it's done. It's simple and only requires a voltmeter or multimeter.

Do that and let me know what you find. Also, explain what symptoms you are experiencing. For example, the engine won't start, or there is an idle problem. I ask because one of the codes indicates there is an open circuit to power the control module. That can cause the vehicle not to start.

Take care,

Joe
