Oil light not turning off and the fuel gauge does not Move

Hi,

The rear electronic control module is tied to the instrument cluster, fuel gauge, and oil pressure light via what is called a CAN bus. CAN stands for controller area network. I would recommend checking the wiring at that module as well as at the instrument panel for a location where the two wires (blue and yellow) have crossed or a connector has failed. It seems (and this is a theory) power from the fuel gauge is being sent to the oil light and not the gauge.

If you look at the pics below, I included the wiring schematic related to this issue. I highlighted the wires I recommend checking. Here is a link you may find helpful:

Also, I strongly recommend having the CAN bus system scanned. As mentioned, the can is a network that ties all modules together via a few wires. If there is a fault in the module, it should be indicated via a diagnostic trouble code.

Here is a quick video showing how it's done:

Let me know what you find or if you have other questions.

Hi,

You are very welcome. If you have the chance, let me know what you find or if you have other questions.

Take care,

Hi,

The instrument cluster is on the dash. The wiring shown is behind the cluster. The connector to the cluster is what is shown.

As far as a different schematic, this is all I have. I'm sorry about that.

Let me know if you can find the cluster wiring.

You are welcome. Let me know if there is something I can do to help.

We can definitely help with this but unfortunately, we need to get a new post started on this because this issue is not the same as listed in the subject line of this post.

https://www.2carpros.com/questions/new

Basically, we need to keep each post to one topic just so that if others have the same issue, they can find it.

More than likely they will not find this specific issue under this post.

Sorry for any inconvenience. Thanks
