CANTCU has an integrated fault code reader that can read and clear fault codes from the transmission. Codes are displayed with their BMW HEX-code and description. The status of the fault code is also displayed (Active/Not active).

NOTE! Having another tester present on CAN1 (KDCAN cable etc) will interfere with CANTCU fault code reading functions and can result in weird results when trying to read/clear fault codes. Clearing fault codes using CANTCU does not clear information/history fault memory.
