Indirect TPM systemsIndirect TPM systems

• As the tires wear the system recalculates the variation in speed for each sensor

• If there is a puncture the pressure inside a tire is reduced and the overall diameter of the tire becomes slightly smaller

• As a result the speed of the wheel increases slightly

• This sudden increase in speed variation triggers the system to turn on the ‘Tire’ pressure warning light and sets a chassis code

Indirect TPM system resetIndirect TPM system reset

• Whenever new tires are installed or tires are rotated the TPMS system needs to recalculate the sensor variation table

• Each manufacture has its own procedure• The most common is a reset button in the

fuse box– With the ignition key on the TPMS reset button is

depressed for 5 seconds or until the TPMS warning light goes out

Smart vs. Dumb TPMS systemsSmart vs. Dumb TPMS systems

• ‘Dumb’ TPMS systems do not indicate which tire[s] has low pressure when the TPMS warning light is illuminated. This eliminates the need to re-register the sensors each time the tires are rotated

• ‘Smart’ TPMS systems will display the location of the tire when the TPMS system receives a low pressure signal from a sensor. This requires that the sensors be re-registered each time the tires are rotated.

• In a dumb system the TPMS module knows the ID # for all the sensors but it does not keep track of where each sensor is currently located
