Question

which type of memory stores diagnostic trouble codes (dtcs) and learned val and can be erased with a scan tool or by disconnecting the vehicles battery? a) eeprom b) kam c) ram d) prom

Explanation:

Keep Alive Memory (KAM) is a type of vehicle computer memory that stores temporary data like Diagnostic Trouble Codes (DTCs) and learned values. It relies on battery power, so it can be erased by disconnecting the battery or using a scan tool. EEPROM requires specific programming to erase, RAM loses data immediately when power is cut without needing a scan tool, and PROM is non-erasable/non-modifiable after manufacturing.

Answer:

B) KAM
