Select the corresponding fault code and follow the further instructions of STAR DIAGNOSIS

It is essential that all test steps are processed completely, even if a fault has been found in the meantime. After the complete processing of the test steps a 4-digit random number, the 8-digit ID code and calculation type XN is displayed in STAR DIAGNOSIS.

9

Enter the 4-digit random number, 8-digit ID code and the calculation type XN in the VeDoc

To carry out the work an access authorization for VeDoc is required.

After entering the data, the VeDoc outputs a 12-digit encrypted random number.

10

Enter 12-digit encrypted random number in STAR DIAGNOSIS and confirm with "F3"

When the entry is correct the fault code and the torque limitation possibly connected with it is erased automatically.
