It can be used to store a variety of things, such as the serial numbers and other distinctive information that is found in nearly everything connected to Ethernet and the chip that is used in printers, charge cards and even blood glucose monitors. It can also be used to store data sequences that control the microcontrollers' operation and also to provide a means of recovering from power-on reset conditions.<br><br>The basic EEPROM chip contains two field effect transistors. The floating gate is located on one side, while the control gate is on the other. When the device is powered with electricity, electrons are released from the gate, and they can be held in either a 0 or 1 state dependent on the voltage that is applied. The EEPROM can be read by determining the state of these transistors.<br><br>If the EEPROM is in the "0" state there is no value. If the EEPROM state is "1" it has a 1 value. In between these states, there is no stored information, but it is possible to write to. The EEPROM can also be erased using a specific voltage to the gate for a short period of time.<br><br>The EEPROM is advantageous because it can be erased and written to without external circuitry. This makes it a great choice for systems that must be updated frequently for example, remote keyless microcontrollers in systems. There are various types of memory chips that provide similar functionality, but are better suited for long-term storage.<br><br>Modern flash memory chips, for instance, are very popular and are used in computers as well as digital cameras.

There are numerous protocols however the most well-known ones are SAE J1850 which is utilized in Ford and a few GM vehicles, ISO 14230-4 (KWP2000) and ISO 14230-4 (KWP2000), which is used in a variety of European or Asian vehicles, and CAN, which is used on most US-made vehicles. Some scan tools tell you exactly what the code is referring to. Others will give you the code, and you'll need to do some internet research to determine what it means.<br><br>What is CAS unit?<br><br>The CAS module is a BMW module that manages the antitheft system of the vehicle.

The CAS module is powered by the ignition coil, and is not designed to run on batteries. A transponder chip is integrated in the key to transmit the signal that is coded to the CAS module. This signal is sent through loop antenna (coil) at the lock for ignition.<br><br>CasSystem implements the logic of CAS state. You must create one instance of this class on each instrument that needs to receive information from the CAS. Multiple instances of this class can result in unintended behavior. CasSystem also manages alert messages in addition to providing state data. In order to do this it creates a cas_activate_alert topic that requires event information in the form of an object with the key and priority properties. This topic specifies the ID and optionally the suffix of the alert you wish to activate, as well as its priority level. Once you've activated an alert, the CasSystem will display an alert on the cas_alert_displayed and ca_alert_hidden event bus topics (defined by the CasEvents interface). It will also subscribe to the cas_master_warning_active and cas_master_caution_active topics to consume their statuses.<br><br>How do you program a BMW Key<br><br>BMW offers drivers in the Murrieta area with keyless entry.
