APPENDIX
APPENDIX A: Vehicle Identification Number (VIN)
When using the TECH350 tool, it is important for the user to verify the Model Year to help
insure looking for that proper sensor and using the proper vehicle
COMs when necessary.
By using the vehicles VIN and locate the 10th digit from the left
the user can in most cases accurately determine the vehicle’s
Model Year. Take that digit and reference the chart on this sheet.
This will be the Model Year which needs to be selected on the tool.
APPENDIX B: TPMS SYSTEM REVIEW
When cycling the ignition for off to run, the TPMS tell-tale should come on,
and go off. This would indicate a system with no fault present.
Check the tyre pressures, and adjust to placard.
NOTE: Some vehicles are equipped with sensors in
the spare. Also, with some vehicles, over pressure
may turn on the light.
System problems can range from faulty sensor(s) to
sensors on the vehicle that haven’t been learned to
that vehicle.
