Question

which of the following best describes a characteristic of eeprom. a) it stores information short term during vehicle operation. b) it can be erased and reprogrammed in the vehicle with a scan tool. c) it stores dtcs and learned values. d) it provides the cpu with a permanent set of instructions.

Explanation:

• Option A describes RAM, which is short-term memory.
• Option C: DTCs and learned values are often stored in RAM or non-volatile RAM, not EEPROM's core trait.
• Option D describes ROM, which has permanent, non-alterable instructions.
• EEPROM (Electrically Erasable Programmable Read-Only Memory) can be erased and reprogrammed electronically, which in vehicles is done with a scan tool without removing the memory chip.

Answer:

B) It can be erased and reprogrammed in the vehicle with a scan tool.
