Camera1 Activation Short Circuit to UBAT
Disconnect the activation signal from the camera. Delete the DTC. Restart the infotainment system, activate camera1 and check if the DTC remains active. If so, check if the wire between the infotainment system and the camera activation signal (pin E9) has a short-circuit. Check any short-circuit for the remaining wiring between the camera and the infotainment system If it becomes passive the error probably depends on the camera. Check if the camera has internal short circuit. Note. Before replacing the infotainment system update to the latest available software.
What you'll see
The camera might not work. The infotainment system sends activation signal through pin E9 to camera1. If the activation pin is faulty the camera will not go into standby and consume current even though it's not used.
