Key Fob

Sends a signal to the car's ECU

ECU

Procedures the signal and allows engine start

Ignition Module

Engages the ignition system to start the engine

Relay

Function as a switch activating the starter motor

Common Issues With Push To Start Systems

While push to start ignition systems provide benefit, they can likewise present particular problems. Here are some typical issues:

1. Weak or Dead Key Fob Battery

A typical cause of failure in push to start systems is a weak or dead key fob battery. When the battery power dips, the key fob might not transfer its signal effectively.

2. Malfunctioning Key Fob

Wear and tear can also affect the key fob itself. Internal circuitry might stop working, impeding the fob's communication with the car.

3. Faulty Ignition System

The ignition module may malfunction, stopping working to engage the starter motor when the button is pushed. This might be due to a blown fuse or electrical wiring concerns.

4. ECU Malfunction

In unusual cases, the vehicle's ECU may become defective, leading to interaction concerns between the fob and the ignition system.

5. Proximity Sensor Issues

The push to start system frequently includes a proximity sensor that discovers the key fob's presence inside the vehicle. If this sensor is malfunctioning, the system may not activate.

6. Relay Problems

A broken or malfunctioning relay can hamper the electrical signals needed for the ignition module to operate effectively.
