Some drivers have had their batteries die and had them changed, only to get the parking brake fault warning.

The warning comes as soon as the car is started, or it might be another variation of a similar mistake, like park brake not released/applied, which occurs when you use and then ultimately remove your brake.

However, the brake still functions well even when the notice appears.

This often occurs when your automobile battery is low on charge or completely dead, which also turns off the computer. This means mistakes happen even if you have a new battery installed, and you can ask your dealership to fix the problem.

Using an OBD-II scanner, you may also perform the work yourself. If not, bring your car to the dealership for the best remedy.

#2: The Wires For The Park Brake Are Rusted Or Worn Out

This notice might also appear if a cable connected to your brake system is frayed or broken.

The ABS wire at the wheelbase of your automobile is most likely to blame. It is often covered in insulation and has a wire loom outside. However, your cables could be cut, even if they are insulated.

If your ABS is the issue, you must check the wiring harness above your wheel, near your shock springs. If necessary, you might need to replace the damaged wire. Installing a second wire that is unlikely to be cut is preferable, preferably one that is longer.

#3: Liquids

Your wires may have rusted over time due to liquid exposure if you drive through puddles or in the rain. In addition, error codes may arise if the cables are damaged. Therefore, wherever possible, try to avoid going over puddles.

Start by turning the key in the ignition. But make sure you don’t start the car. After that, press the gas pedal. After then, lower it toward the ground and keep it there.

Your parking brake should be set to brake and hold if you lift the parking brake button. Then, after about five seconds, switch the ignition back on.

If the error notice is still present, you could be dealing with a problem that is not immediately fixable. Unfortunately, no PC reset will assist because of this.

Therefore, you must visit your dealer to have the problem examined and fixed by a professional.
