Subtle lag in audio cues, though JLR workshop documentation notes that core safety chimes (like parking alerts) run on a different higher-priority bus line. 🚦 Primary Causes of the Fault As the automotive industry continues to evolve, the
Land Rovers are highly sensitive to battery health; a battery reading below 12V (e.g., 11.8V) can trigger multiple "phantom" communication and circuit codes. Recommended Diagnostic Steps
Review the official Land Rover factory wiring diagram for your exact model and model year. Identify the specific pins dedicated to the engine speed input/crank signal line running to the amplifier. Use a digital multimeter set to ohms ( Ωcap omega
Because this code is isolated to the premium audio system branch, it rarely triggers a Check Engine Light (CEL) or an "Engine Performance Restricted" warning on your instrument cluster. In most cases, it is discovered passively during a diagnostic sweep using specialist JLR tools like , SDD , or Pathfinder . However, you may observe the following secondary symptoms:
