Tire Pressure Monitor System (TPMS)

The controlling software for the Tire Pressure Monitoring System (TPMS) is located within the CJB. The software detects the following:

• When the tire pressure is below the recommended low pressure value - under inflated tire.
• The location of the tire on the vehicle that is below the recommended pressure.
• Malfunction warning.

The TPMS system comprises:

• CJB located behind the rear seats.
• Tire pressure receiver is located above the roof concole.
• Two front initiators positioned forward of the wheels and behind the fender splash shields.
• Two rear initiators positioned rearward of the wheels and assembled on dedicated brackets located behind the fender splash shields.
• Four sensors, each sensor is integral with a tire valve and located within the tire; the space saver spare wheel is not fitted with a sensor.

The wheel location is performed automatically by the CJB using an 'auto-location' function. This function is fully automatic and requires no input from the driver. The CJB automatically re-learns the position of the wheels on the vehicle if the tire pressure sensors are replaced or the wheel positions on the vehicle are changed.
