Mode
|
(1) |
Virgin State
|
• |
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 Auto-Location, no sensor
wake-up, 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 location / learning
is enabled.
|
|
|
|
2. |
Overview
| •
|
Learn TPMS 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.
|
|
|
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(20-30 kph).
|
| •
|
Confidence reduction is dependent on time which vehicle is driven
at speed greater than or equal to 12.4 mph(20-30 kph).
|
|
Replacement
1.

Other information:
Hub nut tightening sequence
1.
Tighten the hub nuts as follows.
Tightening torque:
107.9 - 127.5 N.m (11.0 - 13.0 kgf.m, 79.6 - 94.0 lb-ft)
•
When using an impact gun, final tightening torque should
be checked using a torque wrench...
Replacement
•
Put on gloves to prevent hand injuries.
•
When removing with a flat-tip screwdriver or remover, wrap protective
tape around the tools to prevent damage to components...
