TIRE PRESSURE MONITORING SYSTEM OPERATION RECORD

Purpose/Function

• The DSC HU/CM stores the operation records and the Mazda Modular Diagnostic System (M-MDS) reads out the operation records and indicates them as shown in the figure below:

NOTE:

• M-MDS indication is indicated in brackets

Tire pressure monitoring system set switch operation record (TPMS Learning Reset Button Record)

• The DSC HU/CM implements the tire pressure monitoring system initialization by pressing the tire pressure monitoring system set switch, and it simultaneously records the following items for a maximum 3 times from the current record as the operation record.

• Elapsed days (Elapsed days)

  NOTE:

  • The M-MDS displays the elapsed days from the start of initialization until the operation record verification with the M-MDS.

  • If the operation record has not been recorded, 65,535 days is displayed however this does not indicate a malfunction.

• Total traveled distance (Odometer)

Tire pressure monitoring system warning light illumination operation record (TPMS Warning Light illumination)

• If the DSC HU/CM detects a low tire pressure, it outputs a tire pressure monitoring system warning light illumination signal, and it simultaneously records the following items for a maximum 3 times from the current record as the operation record.

• Elapsed days (Elapsed days)

  NOTE:

  • The M-MDS displays the elapsed days from when the low tire pressure was detected until the operation record verification with the M-MDS.

  • If the operation record has not been recorded, 65,535 days is displayed however this does not indicate a malfunction.

• Total traveled distance (Odometer)

• Vehicle speed (Speed)

• Maximum vehicle speed (Maximum vehicle speed)

  NOTE:

  • Vehicle speed until the tire pressure monitoring system set switch is pressed from the illumination of the tire pressure monitoring warning light due to a low tire pressure
