What is the reason for the Crown reporting engine immobilizer failure?
1 Answers
Crown engine immobilizer system failure is a computer hardware issue. It is recommended to unplug the various detection points of the computer board and then conduct a test drive. The engine immobilizer system, commonly known as the engine electronic anti-theft system, is an anti-theft system installed for the engine. The ignition key of the car contains an electronic chip, each with a fixed ID. When the ID of the key chip matches the ID on the engine side, the car will start. If they do not match, the car will automatically cut off the circuit, preventing the engine from starting. Method to deactivate the Crown engine immobilizer system: Insert the ignition key into the ignition switch. The stop ECU command receiving coil emits electromagnetic energy, which is received by the capacitor in the electronic chip, converted into electrical energy, and temporarily stored. This is used to transmit the key coding signal. After receiving the coding signal from the key, the receiving coil amplifies it through an amplifier and transmits it to the stop ECU. The stop ECU compares it with the pre-stored identification code in the storage area. If they match, the stop ECU sends a signal to the engine ECU to release the immobilizer system, allowing the engine to start.
