OPERATION
OPERATION
The battery operated tire pressure sensor is both a transmitter and a receiver. The
TPM sensor can be forced to transmit by using a special tool such as a TPM-
RKE Analyzer, or from a transponder. Refer to
TRANSPONDER, TIRE
PRESSURE MONITORING (TPM), OPERATION
. The TPM-RKE Analyzer
has the ability to change the sensor's operating mode to PARK MODE and to
help diagnose a faulty TPM sensor. Using a TPM-RKE Analyzer can take up to a
minute to force a transmission from a sensor.
The TPM sensor can be in one of the following operating modes:
SLEEP MODE
- A new TPM sensor will be in this mode. If placed on the
vehicle as a road tire, the TPM sensor will transmit once every 20 seconds
when the vehicle is driven at speeds over 15 mph (24 km/h). If the vehicle is
not moving, the sensor will only transmit on a pressure change greater then
1 psi (6.9 kPA). Driving the vehicle continuously at speeds over 15 mph (24
km/h) for more then 4 minutes will change the sensor state into 30 BLOCK
MODE. The TPM sensor will not return to SLEEP MODE. Now, if the
vehicle has been stopped for 20 minutes, the TPM sensor state will change
to PARK MODE.
PARK MODE
- This is the correct operating mode when the vehicle is not
moving. The sensor will transmit once every 13 hours to update the WCM,
or will transmit on a 1 psi (6.9 kPa) delta change. The sensors will internally
take a measurement of the tire pressure every minute to determine a change
in tire pressure.
30 BLOCK MODE
- If the vehicle has been stopped for more then 20
minutes, or if the sensor's operating mode was forced to PARK MODE
using a TPM-RKE Analyzer, the sensor's operating mode will transition
from PARK MODE to 30 BLOCK MODE once the vehicle is driven over
15 mph (24 km/h). In this mode, the sensor will transmit once every 15
seconds when the vehicle is driven at speeds over 15 mph (24 km/h) for the
first 30 transmissions. After about 10 minutes of continuous driving above
15 mph (24 km/h), the sensor's mode will change to DRIVE MODE.
DRIVE MODE
- In this mode, the sensor will transmit once every minute
