EPS Module DTCs Present
When the Electric Power Steering (EPS) Module has Diagnostic Trouble Codes (DTCs) present, it can cause the Jeep U0420 Code. This can be due to a faulty or worn out EPS Module, and the only solution is to repair or replace the module. It is important to diagnose the exact cause of the DTCs before replacing the module, as it may be caused by a loose connection or a faulty component.
BCM DTCs Present
Another potential cause of the Jeep U0420 Code is when the Body Control Module (BCM) has DTCs present. This can be due to a faulty or worn out BCM, and the solution is to either repair the existing module or replace it with a new one. It is important to diagnose the exact cause of the DTCs before replacing the module, as it may be caused by a loose connection or a faulty component.
EPS Module Faulty
If the issue is with the Electric Power Steering module, the only solution is to repair or replace the module. In order to determine if the EPS Module is at fault, it is important to diagnose the exact cause of the issue. This can be done by performing a thorough diagnostic test to identify any faults in the module.
FFCM Faulty
The Forward Facing Camera Module (FFCM) can also be at fault for the Jeep U0420 Code. In this case, the only solution is to either repair the existing module or replace it with a new one. It is important to diagnose the exact cause of the issue before replacing the module, as it may be caused by a loose connection or a faulty component.
