Cluster fluctuating?

Hi,

Replacing the entire cluster can be expensive. Therefore, we need to confirm that it is the problem. What I recommend is to scan the can-bus system to determine if there are any codes stored that are related to the cluster.

The different control modules are tied together via a few wires. CAN stands for Controller Area Network. This type of scan will retrieve codes regardless of which module has codes set.

Based on how it is acting, my first thought is a wiring issue or a connector. It won't be a fuse or fusible link because if they fail, they won't work again. Also, metal expands when it gets warm. It will likely be warmer at the end of the work day, and it may be enough to make a better connection. So, check to make sure the connector at the rear of the cluster is tight and in good condition. Disconnect it and see if there is any corrosion or damaged connector pins.

Here is a link that explains how to perform a can-scan:

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

Take care,

Thank you for this info. I was trying a few you mentioned also no codes were stored after scan so possible wiring issue I will proceed further with checking all wiring and update as soon as I figure it out. Much appreciated.
