TECHNICAL SERVICE BULLETIN

SUBJECT

Tire Pressure Monitoring Systems (TPMS) 

MODEL

R50 (MINI Cooper)

R52 (MINI Convertible)

R53 (MINI Cooper S)

INFORMATION

National Highway Traffic Safety Administration (NHTSA) regulations on TPMS:

• By 9/07, all vehicles must utilize a direct monitoring system with a pressure sensor inside each tire to broadcast the tire pressure to a central receiver on the vehicle.
• The yellow tell-tale must illuminate during the NHTSA required test within 20 minutes when there is a 25% loss in tire pressure (any or all of four tires).

TERMINOLOGY

• "Tire Pressure Monitor" (TPM) system will be used for a direct monitoring system (RDC based system).
• "Flat Tire Monitor" (FTM) system will be used for an indirect monitoring system (RPA based system).
• "Reset" will be used instead of "Initialize".

SYSTEM RESET

• Learning process establishes the initial tire pressure level and increases warning sensitivity from 0% to 100 %. This can only take place during driving.
• The learning occurs automatically after reset and its progress can only be checked by using GT1.
• The rate of the learning progress can depend on varied driving situations (accelerating, braking, cornering), tire conditions, and (for direct monitoring systems) electro-magnetic or radio frequency interferences.
• There is no need to perform special learning trials or driving maneuvers to reset the system.
• The first initialization or reset before the customer delivery is performed during QC1 Road Test; however, initialization or reset must be performed after any tire pressure adjustment.

NOTES

• Adjust the tire pressures on all 4 cold tires to the recommended cold tire inflation pressures and then start the initialization/resetting process (see Owner's Manual).
• It is not necessary to drive the vehicle immediately after this operation.
• Ignition can be switched off.
• The control module stores the job and will learn as the driving conditions permit.
• Learning will be done step by step, driving interruptions do not delete the learned status.
