Self Diagnosis Result

In CONSULT-III self-diagnosis, self-diagnosis results and error history are displayed simultaneously.
The timing is displayed as "0" if any of the error codes [U1000], [U1010], [U1300] or [U1310] are detected. The counter increases by 1 if the condition is normal at the next ignition switch ON cycle.
