DTC B1010: Calibration ROM Checksum Error: Description

Microprocessor runs a program after each power up to detect a ROM checksum error. Only requirements are power and ground. Program runs even if voltage is out of operating range. When DTC sets, microprocessor reverts to base operation values programmed for the blocks of data that have failed the ROM checksum test. The blocks of data that have not failed the ROM checksum test are not affected.
