DTC Code	DTC Name
C2A00	ECU Malfunction

DESCRIPTION

If the torque vectoring differential ECU assembly detects one of the following malfunctions in the ECU, it stores this DTC:

An abnormal waveform is output from the sub CPU monitored by the main CPU.
A calculated result of the sub CPU does not match that of the main CPU.
An error in communication between the main CPU and sub CPU occurs.
Read/write values of the RAM do not match.
An internal circuit malfunction is detected in an ECU during its startup routine.
A startup routine does not complete within the specified time.
