The check gauges light can also turn on though when there is any fault that would lead to problems with Your truck's gauges. You should use an OBD II scan tool to determine what the root cause of the problem is. The ECU will be able to let You know what has gone wrong so that You can either fix or replace the damaged components that have caused Your gauges to not work properly.
