Abstract
A portable automotive diagnostic tool (30) for receiving information from an automotive computer of a vehicle. The portable automotive diagnostic tool (30) is battery powered. The portable automotive diagnostic tool (30) comprises a microcontroller (31), a display (32), a keypad (33), a flash memory (34), a SRAM (35), a battery backup circuit (36), a ROM (37), a UART (38), and a port (39). Automotive codes for configuring the portable automotive diagnostic tool (30) are stored in flash memory (34). The automotive codes are compressed to increase storage to the flash memory (34). The flash memory (34) is non-volatile and retains the automotive codes when power is removed. The automotive codes are updated by writing new automotive codes to the flash memory (34). Information or data received from an automotive computer is stored in SRAM (35). The battery backup circuit (36) powers the SRAM (35) to maintain the information to be taken to a different location when the power is turned off.
