👉Nissan Qashqai Radio Not Working? It Wasn’t the Head Unit!😱🛠️

Customer complaint: intermittent radio failure on a Nissan Qashqai with no fault codes stored. The audio unit would randomly go blank while driving, then come back on. With no DTCs present, this required a live diagnostic test drive to properly capture the failure in real time. During testing, I monitored power supply voltage, CAN network communication, and signal inputs from the around view monitor and BCM. When the fault occurred, charging voltage spiked to nearly 16V — far above normal operating range — causing the head unit to shut down to protect itself. The root cause? A faulty aftermarket alternator overcharging the system. Once confirmed, the diagnosis was clear: excessive alternator output was killing module operation. A perfect example of why proper electrical testing beats guessing and replacing expensive parts. In this video, I diagnose an intermittent radio failure on a Nissan Qashqai with no stored fault codes. Using live voltage testing and oscilloscope analysis, we uncover an overcharging alternator producing nearly 16 volts, causing module shutdown. This step-by-step automotive diagnostic process shows why proper testing prevents unnecessary head unit replacement. *Key Points:* No DTCs stored Radio intermittently shuts off while driving Live voltage monitoring revealed 15.8–16V spike CAN communication remained intact Faulty aftermarket alternator confirmed Overcharging caused module shutdownNissan Qashqai radio not working Nissan Qashqai alternator fault Qashqai electrical problems Nissan radio cutting out Car radio shuts off while driving Alternator overcharging symptoms Automotive diagnostics No fault codes but problem Car electrical fault diagnosis Overcharging alternator 16 volts Mechanic diagnostic process #NissanQashqai #CarDiagnostics #AutoElectrical #AlternatorFault #MechanicLife
