P0650 Error: Indicator Lamp Troubleshoot?

[HoumirKinkar]

Greetings, esteemed community! I find myself grappling with an enigmatic issue concerning my car. An elusive P0650 error has surfaced, indicating a malfunction within the indicator lamp – citing low voltage persistently. Despite meticulous scrutiny of my dashboard connections and cables, the mystery persists. My electronic echat engineer posits that the ECU remains unblemished. However, the gravity of this situation looms large in my mind; should a critical event occur, the absence of the check engine light could prove catastrophic. Has anyone encountered such a perplexing dilemma?
