Service mode allows technicians or vehicle owners to perform maintenance, diagnostics, or programming without triggering the immobiliser’s security features.

Service mode temporarily disables the immobiliser’s blocking function. This mode is useful when you need to:

• Perform vehicle servicing or repairs

Without entering service mode, the immobiliser may prevent the engine from starting or cause other interruptions during maintenance.

Before you start, gather the following:

• Your vehicle’s key and acess to the car

• The Ghost immobiliser service button to hand

• A calm, well-lit workspace

  
  

Make sure the vehicle is parked safely with the handbrake on. Avoid attempting service mode activation while driving or in unsafe conditions.

Step 1: Turn the Ignition On

Insert your key into the ignition or press the start button and turn it to the ON position. Do not start the engine yet. This step powers the immobiliser system and prepares it to receive commands.
