EPC Light on intermittently sometimes won't come on at all while driving. System also has Start/Stop System error message.

Hi,

The EPC light, electronic power control light, is usually an indication of an issue with the throttle control system or anything that may affect the system. When this happens, do you ever notice any difference in the vehicle's drivability?

If you haven't done it already, I recommend scanning the can-bus system. CAN stands for controller area network. Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that explains how it's done:

Let me know if that is something you have done or if you can have it done.

Take care,

joe
