See the basic definition of a diagnostic error. This will help you to clarify the main causes of the fault code. You will understand the program of the control unit
Basic DTC analysis according to OBD2 protocol standard.

OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

Basic error definition

Internal Control Module Torque Calculation Performance

Cause of DTC

Rationality check of the positive engine torque request: A positive or negative engine torque request is sent via Controller Area Network (CAN) and no positive or negative torque request was calculated by the shift control software. Rationality check of the positive engine torque request magnitude: A fault is detected if one of the following occur: The actual calculated engine torque request and the delivered engine torque request sent via CAN are both greater than a first threshold for a calibrated amount of time. The actual calculated engine torque and the delivered engine torque request sent via CAN are both greater than a second threshold for a calibrated amount of time. Rationality check of speed gradients during gearshifts: The difference between the actual input speed gradient and the actual output speed gradient multiplied by the actual gear ratio is lower than a calibrated threshold.
