Random Access Memory: RAM stands for Random Access Memory, and it's a type of super-fast storage that your computer uses to hold data it needs in the short term.

Random Access Memory Pointer: RAM Pointers take up the space needed to hold an address, which is 4 bytes on a 32-bit machine and 8 bytes on a 64-bit machine

Ram Test: The module RamTst tests internal microcontroller RAM cells. A complete test is triggered during start-up and shutdown of the ECU or by a diagnostic command. During normal operation, a periodic test is performed (block-by-block or cell-by-cell).

Rest-bus Simulation: Rest-bus Simulation is a technique that can be employed when testing devices on communication networks where the 'rest of the bus' is simulated in order to facilitate testing the controller in question.

Read Data By Identifier: The “Read Data By Identifier” service allows the diagnostic tool to request data record values from the ECU identified by Record Data identifiers.

Request

Response

Routine Identifier: This service is used by the client to perform various project specific functions through OEM-specific routine Identifier. Requestroutineresult – It is basically a request message by client to get the result of service from server.

Read-Only Memory Pointer: A pointer is a number that refers to a specific location in a ROM or memory. They may also be referred to as addresses or offsets. The exact way pointers work vary among different systems, and, in fact, some systems have multiple pointer schemes.
