This service displays vehicle-specific information, such as the vehicle identification
number (VIN), the calibration identification, and the calibration verification number
(CVN), of the vehicle.

This service displays “In-use Performance Tracking” data. It is a record of the
number of times each of the monitor tests have been completed.

Start Communication > ($0A) Display Permanent Trouble Codes
This service displays a record of any “permanent” codes. A permanent status DTC
is one that was severe enough to illuminate the MIL at some point, but the MIL may
not be on at the present time.
Whether the MIL was switched off by clearing codes or because the setting
conditions did not repeat after a specified number of drive cycles, a record of the
DTC is retained by the ECM. Permanent status codes automatically clear after
repairs have been made and the related system monitor runs successfully.

Manual Protocol Selection
Typically the communication protocol is automatically detected when establishing
communication with a vehicle, this service allows you to manually select a protocol,
if automatic detection fails.
Communication protocol is a standardized way of transferring data between an
ECM and a diagnostic tool. Global OBD may use the following communication
protocols (
):
•
ISO 15765-4 (CAN)
•
ISO 27145 (WWHOBD CAN)
•
ISO J1939 (CAN)
•
ISO 9141-2 (K-LINE)
•
SAE J1850 PWM (Pulse Width Modulation)
•
SAE J1850 VPW (Variable Pulse Width)
•
ISO 14230-4 (Keyword Protocol 2000)
•
SAE J2284/ISO 15765-4 (CAN)
IMPORTANT
Using unsupported OBD communication protocols may activate
warning lights and can set network related faults. Only use the manual
selection option when OBD protocol is already known.
