Vehicle CAN Diagnosis
CAN communication status and error counter is displayed.
The error counter displays “OK” if any malfunction was not
detected in the past and displays “0 ” if a malfunction is detected. It
increases by 1 if the condition is normal at the next ignition switch
ON cycle. The upper limit of the counter is 39.
The error counter is erased if “Reset” is pressed.
NOTE:
“???” indicates UNKWN.
