The MG Ruiteng Expressway starts to drive normally and enters the service area. After the flameout, it will report the brake module failure.

There are two reasons: brake system failure and electrical system failure.

1. Brake system failure: The alarm message of brake module failure is caused by brake system failure. It is a problem of brake system components such as brake disc, brake pad, brake oil or brake sensor, which leads to brake failure or abnormal work, and then leads to engine flameout.

2. Electrical system failure: The alarm information of brake module failure is also related to the electrical system. The fault signal of the brake module is caused by circuit fault, sensor fault or electronic control unit (ECU) problem in the electrical system.
