Hi,

The number you have, 7e8, is not code but a menu for the engine data stream. This indicated there are diagnostic trouble codes stored in the engine control module.

At this point, you need to have the computer scanned to identify diagnostic codes. Here is a quick video showing how the CAN is scanned. CAN stands for controller area network. Basically, all the computers/modules are tied together via a few wires. This will provide codes regardless of the module storing them.

Let me know what codes are found and if you have other questions.

Take care,

Joe
