FAQsChrysler PCM's identified with a "V" suffix will need to be vin programmed.
FAQsPrior to replacing the original ECM/PCM, the installer should determine what caused the original to fail. Common areas that cause failures are: poor grounds and powers, bad wiring harness, shorted solenoids/relays.
FAQsWhat steps should I take to assure the original ecm/pcm is causing the issue?
