Operation record use example

For a customer who states that the tire pressure monitoring warning light was illuminated, verify if the customer knows how to correctly use the tire pressure monitoring system set switch, and give them advice on how to use it if necessary.

The following can be understood from the operation record display indicated above.

• Tire pressure monitoring system set switch operation record (M-MDS display: TPMS Learning Reset Button Record)
  • Elapsed days displayed is 65, 535 (displays if operation record is not recorded), and the tire pressure monitoring system set switch has not been pressed even once.
• Tire pressure monitoring system warning light illumination operation record (M-MDS display: TPMS Warning Lamp illumination)

• The DSC HU/CM detects a low tire pressure four days ago, and the total traveled distance (M-MDS display: Odometer) at that time was 403 km {250 mile}, and the vehicle speed (M-MDS display: Speed) was 38 km/h {24 mph}, and the maximum vehicle speed from when the pressure monitoring system warning light illuminated was 101 km/h {62.8 mph}.

Based on the above information, provide the following advise, as there is the possibility that the customer does not understand how to correctly use the tire pressure monitoring system set switch.

• If the tire pressure monitoring warning light was illuminated, it will be necessary to adjust the tire pressures on all four tires to the specification and initialize the system by pressing the tire pressure monitoring system set switch. (See TIRE PRESSURE MONITORING SYSTEM INITIALIZATION PROCEDURE .)
• If the vehicle is driven at high speed with low tire pressure, there is the danger of a tire rupture occurring.
