1 Answers
The reasons for the Mazda 6 anti-theft alarm sounding without cause are as follows: Reason 1: The sensitivity of the anti-theft alarm is too high. There is a sensitivity adjustment on the vibration sensor of the anti-theft alarm, and a slight adjustment can be made. Reason 2: Faulty grounding wire of the main control door. Commonly known as a faulty door switch. Below is relevant information: 1. Anti-theft system: The engine anti-theft system of the Mazda 6 sedan consists of a key with an embedded chip, an onboard antenna, and a power control module (PCM). When the correct password signal from the key chip is received, the anti-theft controller communicates with the engine control unit before deciding whether to allow the engine ignition and fuel injection system to operate. Otherwise, the fuel pump and injectors will stop working. Without an ignition signal, the starter cannot operate. 2. Transmitter: The remote control transmitter of the car's remote anti-theft system is composed of a password signal generator, keyboard input circuit, wireless transmission circuit, etc., with an operating frequency of 256～320MHz, typically 315～318MHz. The operating power is +12V, and the remote control distance is about 30m. For ease of carrying, a miniature keychain design is commonly used.
