Usage Scenarios
Engine Won't Start: If the relay controls the fuel pump and it fails, the engine may not start because the fuel is not reaching the engine.
Overheating: If the relay controls a cooling fan and it fails, the engine could overheat.
Non-Functioning Lights: If the relay controls headlights or fog lights, those systems may stop working or have intermittent power.
Electrical Issues: Any failure could cause erratic behavior in the components it controls, such as flickering lights or malfunctioning cooling fans.
