3. Upon receipt
Upon receipt, check packing and product components for damage in the presence of the
carrier. Liability for transport damage attaches to the forwarding agent or carrier.
Report any damage, giving details of the nature and severity of the damage, in the
shipping document and file a claim against forwarding agent or carrier.
4. What is a TPMS system?
The TPMS or Tire Pressure Monitoring System continually monitors tire pressures and
temperatures and sends the information to the vehicle's body computer to have it
displayed on the instrument panel. The system is made up of an ECU placed inside the
vehicle cab that receives radio frequency pressure and temperature signals from four
sensors installed inside the tires.
When the vehicle is running, the sensors transmit their signals every 20-30 seconds
approximately. In the event of a significant pressure variation, transmission interval is
shortened to 8-10 seconds.
When the vehicle is at standstill, transmission interval may vary between 10 and 40
minutes, depending on the type of sensor installed.
5. TPMS indicator lights
Outlined below are the most significant TPMS indicator lights.
Depending on the type of vehicle, this light may
indicate one of the following conditions:
Turns on to indicate that the pressure of
one or more tires is above or below the
specified rated pressure.
Turns on to indicate a TPMS malfunction
(for instance, when one of the sensors is
malfunctioning).
Light operation may vary to differentiate
indications when tire pressure has crossed
the warning or alert thresholds.
