The receiver as a sole part is shipped in this state. Replacement parts should therefore arrive in this state.
•
In this state, there is no sensor monitoring and no DTC monitoring.
•
The state indicates that platform specific parameters must be written to the receiver and that sensors are un-learned.
(2)
Normal State
•
In order for tire inflation state and DTC monitoring to occur, the receiver must be in this state.
•
In this state, automatic sensor learning is enabled.
(3)
Test State
•
This state is only used in manufacturing plant to check RF transmission between sensor and receiver.
2.
Overview
•
Receives RF data from sensor.
•
Uses sensor data to decide whether to turn on TREAD Lamp.
•
Learn TPM sensor for under inflation monitoring automatically.
•
Uses sensor information, distance travelled, background noise
levels, Auto-learn status, short / open circuit output status, vehicle
battery level, internal receiver states to determine if there is a
system or a vehicle fault.
Operation
1.
General Function
•
Auto-learn takes place only once per Ignition cycle.
•
On successful completion, 4 road wheel sensor ID''s are latched into memory for monitoring.
•
Until Auto-learn completes, previously learned sensors are monitored for under inflation / leak warnings.
2.
General Conditions to Learn New Sensors:
•
Receiver must determine that it is confident that sensor is not temporary:
a.
Uses vehicle speed.
b.
Uses confidence reduction of previously learned sensors.
•
Typical time at driving continuously over 15.5 mph(25 kph) to learn a new sensor is up to 20 minutes.
3.
General Conditions to Un-Learn a sensor that is removed:
•
It takes less than 20 minutes at 15.5 mph(25 mph).
•
Confidence reduction is dependent on time which vehicle is driven at speed greater than or equal to 12.4 mph(20 kph).
Removal
1.
Remove the tire.
(Refer to Tires/Wheels - "Tire")
2.
Remove the screw with torx driver (A).

Replacement
When the receiver first arrives for replacement:
a.
It will be in Virgin State.
b.
It will not be configured for any specific platform.
c.
It will ...
Replacement
•
Put on gloves to protect your hands.
•
When prying with a flat-tip screwdriver, wrap it with
protective tape, and apply protective tape around the related parts, to
prevent damage.
