How to Bypass Ignition Switch to Start Car
If you have trouble starting your car, the ignition switch may be damaged. If you have a service manual for your car, you can bypass the ignition switch to start your car. If you don’t have a service manual, you can also bypass the ignition switch by following these steps.
Tools Needed to Bypass the Ignition Switch
To bypass the ignition switch, you will need a set of essential tools. It would be best if you had the following tools on hand:
- A car battery.
- A wire connector.
- A screwdriver.
- A pair of needle-nose pliers.
- A flashlight.
Hotwiring
The first step is to remove the ignition switch. It is the part that turns on and off the car. The switch is located in the center of the steering column and has two wires connected to it.
If you’ve older cars built before the mid-1990s, this method may work for you. Locate the steering wheel column once inside the vehicle. Remove the plastic cover that protects all internal components. It should reveal all necessary components.
Then, look for the wiring harness connector. Because there are so many cables and wires in this area, it may be challenging to find the specific connector. However, it is usually found in the center of the steering column. Other wires, cables, and connectors are associated with the lights.
You must locate the connectors for the battery, ignition, and starter.
The yellow and brown wires are connected to the ignition. The red ones go with the battery. Strip an inch of insulation from the battery wires and twist them together.
Connect the ignition on/off the wire to the battery wire, and the lights will turn on, and the electrical parts will begin to work. Cut the starter wire half an inch short and connect it to the battery wires to start the engine. Now it’s time to start the engine.
The Screwdriver
The next step is to use a screwdriver to loosen the screws on the ignition switch. You should remove the ignition switch, but you may need to remove the cover.
This method may also work, but be cautious because it has the potential to wreck the ignition switch. It will also teach you how to start a car that has a broken ignition switch. Then, as if it were a key, insert the screwdriver into the keyhole and turn the ignition to start the car.
Jumper Cables
If you are unable to start your car, you may have a damaged ignition switch. To bypass the ignition switch, you will need jumper cables. Connect the battery’s positive terminal to the positive terminal of the ignition switch. You should use the positive terminal because it’s usually the most current terminal. The solenoid will be activated, and the car should start.
How to Check if the Ignition Switch Works
Multimeter Test
An ignition switch powers your car’s ECU and ignition coil. It means your ignition switch has two wires coming out of it.
- Place the ignition switch in the off position when using a multimeter.
- Switch the power feed wire with the positive probe of the multimeter and the negative wire with any unpainted metal in your car.
- Next, try to kickstart the engine while keeping an eye on the multimeter reading.
- If the voltage reading is less than 90% of the battery voltage, you have a faulty ignition system.
Light Test
A 12V test light can be used in the absence of a multimeter.
- Turn the key off and disconnect the module’s cable connector from the starter solenoid’s terminal. It prevents your car from starting when the key is turned to the on position.
- Return to the start position with the key.
- The red wire should be connected to the ignition coil battery post and the test voltage.
- Connect the white wire from the ignition switch to the start position.
- The lamplight will turn on if your ignition switch is working correctly. Otherwise, you have a bad ignition switch.
