CID 2548 CAT Fault Code

Cause :

The job of the Starter Relay Circuit is to provide a power source to the starter to crank and start the engine. Depending on the specific vehicle and its drivetrain configuration, there can be multiple components involved in this process.Associated with low engine fluid pressure. The reason most likely is the lack of oil in the engine, so first of all you need to check the amount of consumable. You should also make sure that the engine fluid pressure sensor is working.
