Installation Mode
EMF installation mode is required for the purposes of replacing the EMF actuator unit or the brake cables. The EMF can be set to installation mode with the aid of the BMW diagnosis system. This mode is comprised of two subfunctions:
- Setting the EMF actuator unit to the installation position
- Preventing the EMF parking brake function.
To set the unit to the installation position, the brake cables are extended to the maximum length. That is the essential requirement for being able to remove and refit the cables.
While work is being carried out on the actuator unit, the brake cables or the duo-servo parking brake, the EMF must not be inadvertently or deliberately applied. Doing so would risk causing injury. Installation mode prevents the EMF parking brake function.
That means that pulling out the parking brake button as if to apply the parking brake has no effect.
Installation mode is indicated on the instrument cluster by the parking brake indicator lamp flashing yellow.
Installation mode can be cancelled in two ways:
- By the performing the service function "Reset installation mode" using the BMW diagnosis system
- By driving the vehicle; when doing so, a minimum speed must be exceeded.
Once installation mode has been successfully cancelled, the parking-brake indicator lamp on the instrument panel goes out.
