Mode
| (1) |
Virgin State
| A. |
The receiver as a sole part is shipped in this state. Replacement parts should therefore arrive in this state. |
| B. |
In this state, there is no Auto-Location, no sensor wake-up, no sensor monitoring and no DTC monitoring.. |
| C. |
The state indicates that platform specific parameters must be written to the receiver and that sensors are un-learned. |
|
| (2) |
Normal State
| A. |
In order for tire inflation state and DTC monitoring to occur, the receiver must be in this state. |
| B. |
In this state, automatic sensor location / learning is enabled. |
|
|
| 2. |
Overview
| A. |
Receives RF data from sensor. |
| B. |
Uses sensor data to decide whether to turn on TREAD Lamp. |
| C. |
Learn TPM sensor for under inflation monitoring automatically. |
| D. |
Uses sensor information, 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. |
|
| 1. |
General Function
| A. |
Auto-locate/learn takes place only once per Ignition cycle. |
| B. |
On successful completion, 4 road wheel sensor ID's, together
with their respective road wheel positions are latched into memory for
monitoring. |
| C. |
Until Auto-learn completes, previously learned sensors
(together with their respective locations) are monitored for under
inflation / leak warnings. |
|
| 2. |
General Conditions to Learn New Sensors:
| A. |
Receiver must Auto-Locate 4 road sensors. |
| B. |
Auto-location / learning only functions when speed is more than 25 kph (approx. 15 mph). |
| C. |
Receiver must determine that it is confident that sensor is not temporary: |
| 2) |
Uses confidence reduction of previously learned sensors. |
|
| D. |
Typical time at driving over 25 kph (15.5mph) to learn a new sensor is up to 10 minutes. |
|
| 3. |
General Conditions to Un-Learn a sensor that is removed:
| A. |
It takes less than 10 minutes at 20~25kph. (15 ~ 15.5mph) |
| B. |
Confidence reduction is dependant on vehicle speed and the number of sensors known to the receiver. |

Removal
Tire Removal
1.
Deflate tire & remove balance weights.
•
The tire bead should be broken approx. 90° from the valve side of the wheel. The bead breaker sho ...
Replacement
When the receiver first arrives for replacement:
1)
It will be in Virgin State.
2)
It will not have any sensor ID's memorized.
