A shorting bar in the form of a metal piece is one typical type of device to provide the short-circuit function. A shorting bar is attached to the housing of a connector, with resilient contact portions urging against and electrically connect two or more contact terminals.
What does shorting a terminal mean?
In the context of any two terminals of a circuit: A short circuit implies that the two terminals are externally connected with resistance R=0 , the same as an ideal wire. This means there is zero voltage difference for any current value.
Is there a recall on BMW airbags?
Like 18 other automakers, BMW has issued sweeping recalls for vehicles with potentially explosive Takata airbags. Of the 1.78 million airbags BMW has recalled, almost 700,000 (about 40 percent) have yet to be replaced.

How much is an airbag sensor for a BMW?
The average cost for a BMW 328i air bag crash sensor replacement is between $492 and $513. Labor costs are estimated between $83 and $104 while parts are priced at $409.
What sensors trigger airbags?
In the event of a crash, the crash sensor (an accelerometer) sends a signal to the airbag control unit. This control unit triggers the inflation device, which generates nitrogen gas by igniting a mixture of sodium azide (NaN3) and potassium nitrate (KNO3).
What causes shorting?
They occur when a low-resistance path not suited to carry electricity receives a high-volume electrical current. In simpler terms, short circuits happen when hot wire touches a conductive object it’s not supposed to. The result of a short circuit can be appliance damage, electrical shock, or even a fire.
What is a shorting device?
In protection circuits, the short-circuiting device protects HV installations by preventing potential increases in voltage from induction by fixing the common point to the earth potential.
Why CT terminals are shorted?
Detailed Solution. The secondary side of the current transformer is always kept short-circuited in order to avoid core saturation and high voltage induction so that the current transformer can be used to measure high values of currents.
Which would indicate a short to ground?
Measure the resistance from the voltage input to ground. If it is 0, or close to it, there is a short circuit. Make sure that you remove the power from the voltage input before doing the measurement.
What does shorting to ground mean?
A short to ground is a short circuit of a terminal, a board trace, or a harness connected with a terminal to GND.
What is a short to ground fault?
Ground fault short circuit occurs when the hot wire carrying current comes into contact with some grounded portion of the system. It can be a grounded metal wall box, bare ground wire or a grounded portion of an appliance.
Do BMW recalls expire?
