What is the battery safety terminal on a BMW?
The Battery Safety Terminal (BST) is a device which is used to minimise the risk of any electrical fire in the engine bay if the vehicle is involved in a collision. BMW have been using BST’s as part of their safety package for around 20 years; a cutaway section of the BMW device is shown below in Figure 1.

What is BST cable?
BST Metal detectable cable ties feature a food safe metal additive, dispersed evenly and completely throughout the entire polyamide 6.6 body of the cable tie. These cable ties have an operating temperate of -25°C to 65°C, and can be used as part of a HACCP process or BRC procedures.
What happens if you don’t register a new battery in a BMW?
If the battery replacement is not registered, the power management will not function properly and can lead to functions being limited by individual electrical consumers being switched off or having their power consumption reduced.

What does the battery distribution box do?
The Battery Junction Box (BJB) is a switching unit for the battery in an electric vehicle. It connects or disconnects the components in the vehicle, which need energy from the battery. With one or more bus interfaces, this component is networked with the entire vehicle.
What causes a BMW not to start after accident?
Your Inertia Switch Trips, Causing Your Car Not to Start The most likely reason a car will fail to start after a minor accident is a tripped switch that cuts power to the vehicle’s fuel pump. Many cars include an inertial switch that will stop feeding electricity to its fuel pump after an accident.
At what speed do airbags deploy?
Typically, a front airbag will deploy for unbelted occupants when the crash is the equivalent of an impact into a rigid wall at 10-12 mph. Most airbags will deploy at a higher threshold — about 16 mph — for belted occupants because the belts alone are likely to provide adequate protection up to these moderate speeds.
At what speed do airbags deploy in a rear end collision?
Airbag Injuries Airbags usually deploy if a collision happens when you are traveling at more than 20 miles per hour.
Can you bypass battery current sensor?
Current will bypass the battery current sensor and its readings won’t be accurate.
How do you test an IBS sensor?
Once the scanner is plugged in, turn the ignition on, but don’t start the engine. Scroll through the menus on the scanner, locate the DME option, and scan for fault codes. If you see “299B DME Intelligent Battery Sensor” or “002E8D DME: Intelligent Battery Sensor, signal transmission”, there is a problem with the IBS.
How do you reset terminal 30?
There is no such thing as a terminal 30 reset. Try disconnecting the battery as explained in post above yours.
