What is an EEPROM?
The EEPROM is a non-volatile memory chip that can be erased and reprogrammed. It can be used to store a variety of things, including serial numbers as well as other unique information in almost anything connected to Ethernet as well as the chip that is used in printers, charge cards, and even blood glucose monitors. It can be used to store information that controls the operation of microcontrollers as well as a way to recover from power-on reset situations.
The fundamental EEPROM chip is comprised of two field effect transistors. One is a floating gate, and the other is a control gate. When the device is turned on the electrons are released. They are trapped in a 0 or a 1 state based on the voltage applied. This transistor state can be used to read the EEPROM.
If the EEPROM state is "0" is the state, it has 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 able to be written to. EEPROMs can be erased by a short time of the voltage that is applied to the gate.
The advantage of the EEPROM is that it can be written to and erased without the need for any external circuitry. This makes it a great choice for systems that must be updated frequently like remote keyless microcontrollers for remote systems. However there are other memory chip types that offer similar functionality, and are better suited for long-term storage and retrieval of large files.
Modern flash memory chips are used in computers and digital cameras. These are used to store multimedia files for both long-term storage and retrieval. However, they aren't considered to be EEPROMs, and their core functions are different from those of genuine EEPROMs. However, EEPROMs continue be used extensively due to their versatility and ability to store tiny amounts of data in a small space.
What is OBDII?
In the past, many car manufacturers used their own diagnostic systems to diagnose car problems. In 1996, the government mandated that all cars utilize a standard system for reading diagnostic codes. This new system, which is known as OBD-II, uses the same port and diagnostic code system across all makes and models of vehicles that are sold in the US. This means that if you encounter an issue with your vehicle, it will be easy for any mechanic to pinpoint the cause by plugging in a specific tool.
The OBD-II detects a variety of errors within the engine and other components using the standard diagnostic plug. The information is stored in the computer of the car to be later analyzed. This lets the system detect and repair faults before they cause major damage. The mechanic can connect an OBD-II scan tool to the port and it will display error codes and tell them where they came from.
Scan tools have more processing capacity than code readers and are able to read more error codes. They also display live data graphs and save data for later analysis. Certain tools are capable of performing complex tasks like reprogramming an ECU or supplying options to improve performance. These tools are utilized by professional auto technicians and are generally more expensive than scanners for simple tasks.
When connecting a scan tool to the OBD-II port it will automatically recognize what protocol it is using and then communicate with the vehicle using the appropriate pins. There are many protocols. The most popular are SAE J1850 (KWP2000), used by Ford and certain GM automobiles ISO 14230-4, utilized in various European and Asian vehicles, and CAN. Some scan tools will even provide you with the code means, whereas others will provide the code and will require an internet search to figure out what it means.
What is a CAS unit?
The CAS module is an BMW device which controls the antitheft feature of the vehicle. The system works by taking a coded signal from the fob of the key and verifying it with the CAS module. The CAS module will send an enable signal to the engine control unit if it believes the signal is valid. If not the signal is valid, the engine will not start.
A BMW CAS module malfunction can cause a variety of signs, including key fob not working problems or alarm activation issues. Other symptoms include central locking issues, and warning lights on the dashboard. If you're experiencing any of these symptoms, it's important to have the CAS module inspected by a professional as quickly as possible.
The CAS system makes use of the BMW ICOM VCDS to communicate with the engine and other vehicle systems. The VCDS is connected to the CAS using an extra cable that has an DIN connector at the end. The VCDS can perform a number of functions, including displaying error codes or altering the timing of the ignition. It also has a variety of security features that shield the vehicle from theft.
BMW vehicles come with the CAS key module addition to the ICOM VCDS. The CAS module is powered by the ignition coil, and is not designed to use batteries. The key is equipped with a transponder that transmits the coded signal. This signal is sent through an antenna loop (coil) at the lock for ignition.
The CAS state logic is implemented by the CasSystem class. You must create one instance of this class on every instrument that requires information from the CAS. Creating multiple instances of this class may result in undesirable behavior. CasSystem also manages alert messages in addition to providing state information. It does this by publishing a cas_activate_alert subject that requires event information as an object with key and priority properties. This topic specifies the ID and optionally the suffix of the alert that you wish to activate, along with its priority level. Once you've activated the alert and the CasSystem will publish an alert on the cas_alert_displayed as well as the cas_alert 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.
