What is the reason for the car starter fault light to light up? What's wrong with the car starter not working?

The starter is actually the motor of the car, which mainly converts the battery's electrical energy into mechanical energy, and then drives the engine to start. We all know that the car will perform a self-check when it starts. At this time, the indicator light on the dashboard will light up and then go out. If it does not go out, you should consider the corresponding applause. So what is the matter with the starter fault light on?

What is the reason for the car starter fault light to come on?

It indicates that the engine has an electronic control system failure. However, the failure can be divided into true failure and false failure. For false failure, use the diagnostic instrument to clear the fault code, and the fault light will go out. For true failure, use the diagnostic instrument to retrieve the fault code, and then clear it after eliminating the actual fault according to the fault code, and the fault light will go out!

The fault code indicates a solenoid valve failure, which is not necessarily a problem with the solenoid valve. It may also be a problem with the circuit, the VAONS adjustment wheel, etc.

Why does the car starter not work?

The symptom of a broken car starter is that the starter does not rotate. When the starter switch is turned on, the starter does not rotate.

Reasons why the starter fails to work:

(1) The battery is low or the wires are loose or the terminals are dirty, resulting in poor contact.

(2) The starting electromagnetic switch coil is broken or the contact plate has poor contact.

(3) The starting relay contacts are burned out, and the relay magnetic coil is broken or burned out.

(4) The armature shaft inside the starter is bent or the bearing is too tight, the rectifier is dirty or burned, the brushes are worn too short, the springs are too soft and cannot make contact, the armature coil or field coil is short-circuited, open-circuited or grounded.

(5) Failure in starting the anti-theft system.

Why is the starter weak when starting?

1. Measure whether the battery current reaches the specified value;

2. Check whether the positive and negative wires of the battery are in poor contact;

3. The starter rotor is short-circuited or the front and rear bearings are damaged, causing the starter to become powerless.
