خرابی لامپ نشانگر یا ایراد صفحه کیلومتر

A warning lamp that cannot illuminate, either because the bulb has failed or because the cluster driving it has. Modules monitor their own lamp circuits, so this is detected and reported even though nothing about the vehicle's function has changed.

The real consequence is that a warning can no longer be given, which matters most for the lamps indicating a system has degraded rather than failed — the code becomes the only thing saying the warning system is broken. Check the bulb and holder first on vehicles that still use them; on a cluster with LEDs or module-driven lamps the fault is usually a failed driver inside the cluster. An LED fitted in place of a filament bulb produces the identical code by drawing too little current to be detected.
