Kia Troubleshooting Questions? Ask a Mechanic
Hello and welcome to just answer, my name is ***** ***** master tech here to help. I cannot see or hear your vehicle so I rely on your input so I can help you better. I read your notes and am ready to respond. When diagnosing a P0650 code, it is important to record the freeze frame information and then duplicate the code setting conditions with a test drive at the recorded freeze frame conditions. Carefully watch the serial data stream PID values of MIL command and MIL actual. If they disagree at anytime, then you may have verified the problem. I always remove the bulb from the Instrument Cluster and verify the power source, the PCM provides the ground. I do this because the root of the problem may the Instrument Cluster itself. It never hurts to scan the data and codes for the Instrument Cluster and the BCM or Body Control Module. Study the applicable wiring diagram and verify the existence of excellent continuity between the PCM and the Instrument Cluster and MIL socket.
