What does fault code B133029 mean?

[DelPhoebe]

Fault code B133029 means: The vehicle anti-theft alarm system has an intermittent alarm, and the anti-theft alarm sensor has an unreliable signal. Below is an extended introduction to the fault code: After troubleshooting the vehicle, it is often necessary to clear the fault code. When clearing the fault code, it is essential to strictly follow the specific method designated for the particular vehicle model. Under no circumstances should the negative battery terminal be disconnected as a simple and arbitrary method to clear the fault code. Otherwise, it may lead to the following two issues: 1. Some vehicle models' control computers may lose "historical records." Most vehicle models' central computers have memory functions. If the negative battery terminal is disconnected, the engine operation data stored in RAM (random access memory) will be automatically cleared. This is why some people find that after maintenance and clearing, the vehicle's performance remains poor for a long time, or the previous fault code reappears shortly after driving. 2. It may cause the loss of normal functions. A common example is the audio lock function. In such cases, a complicated repair procedure is required to decrypt the audio system before its original functionality can be restored.
