Vehicle sensor coding
This function allows reprogramming the ID codes of all sensors present on the vehicle.
The modes to carry out this operation are the same mentioned in the previous
paragraph.
In case of "automatic" coding, the software will prompt to approach all 4 wheels of the
vehicle and to acquire the ID codes; then connect to the vehicle diagnosis socket to save
the data in the control unit.
In case of "manual" procedure the sw will prompt to manually enter the 4 codes in the
instrument and to connect the EOBD cable to the vehicle diagnosis socket to carry out
the reprogramming procedure.
This function can be activated from the main menu by selecting the vehicle and then the
"vehicle code".
24.3.
Vehicle electronics control unit Errors and Faults reading
The TPMS-EOBD allows reading also the codes of the vehicle faults to immediately
diagnose the vehicle electronics problems. To enable this function select the vehicle,
then "Vehicle Diagnosis" and "Error code reading". The message "No errors" will be
displayed if no error is present. Otherwise the display will show the error code provided
by the control unit, as well as the error description and its status (if available):
ATT indicates the current error when the instrument communicates with the control
unit.
MEM indicates that the error is no longer present (but memorised) when the relevant
datum is requested to the control unit.
Pay particular attention to the error state in case of problems with sensors since they
transmit data only when the vehicle is moving.
For this reason the relevant fault could be missing because the control unit is not
supposed to receive that information from the vehicle.
Because of the display dimensions only 2 faults can be displayed at the
same time. If more than 2 faults are present use the "up" and "down"
arrows to view the other present faults.
