Circuit Description

The VCM EEPROM contains data essential to running the engine and transmission. VCM program stores this data in the EEPROM. This data remains in the EEPROM even if battery is disconnected. At power-up, VCM checks the integrity of this data. If the checksum of the EEPROM does not match a predetermined value, DTC will set. DTC will also set if VCM is unable to correctly read data from EEPROM memory.
