Wheel /tire noise, vibration and harshness concerns are directly related to vehicle speed and are not
generally affected by acceleration, coasting or decelerating. Also, out-of-balance wheel and tires can
vibrate at more than one speed. A vibration that is affected by the engine rpm, or is eliminated by
placing the transmission in Neutral is not related to the tire and wheel. As a general rule, tire and
wheel vibrations felt in the steering wheel are related to the front tire and wheel assemblies.
Vibrations felt in the seat or floor are related to the rear tire and wheel assemblies. This can initially
isolate a concern to the front or rear.
Careful attention must be paid to the tire and wheels. There are several symptoms that can be caused
by damaged or worn tire and wheels. Perform a careful visual inspection of the tires and wheel
assemblies. Spin the tires slowly and watch for signs of lateral or radial runout. Refer to the tire wear
chart to determine the tire wear conditions and actions

Front Wheel Alignment

When using a commercially available computerized wheel alignment equipment to inspect the front
wheel alignment, always position the vehicle on a level surface with the front wheels facing straight
ahead.
Prior to inspection, make sure that the front suspension and steering system are in normal
operating condition and that the tires are inflated to the specified pressure.

Description

TREAD Lamp
- Tire Under Inflation / Leak Warning.

1. Turn on condition
A. When tire pressure is below allowed threshold
B. When rapid leak is detected by the sensor.
C. Indicates that tire needs to be re-inflated to placard pressure / repaired.
2. Turn off condition
A. Under-inflation ; When tire pressure is above (warning threshold + hysteresis).
B. Rapid Leak ; When tire pressure is above (leak warning threshold).

DTC Warning
1. Turn on condition
A. When the system detects a fault that is external to the receiver/ sensor.
B. When the system detects a receiver fault.
C. When the system detects a sensor fault.
2. Turn off condition
A. If the fault is considered as 'critical', then the lamp is held on throughout the current Ignition
cycle (even if the DTC has been demoted). This is because it is important to bring the problem
to the drivers attention. On the following Ignition cycle, the demotion conditions will be re-
checked. If the demotion conditions occur, the lamp will be turned off. It will be held on until
DTC demotion checking is completed.
B. 'Non critical' faults are those that can occur temporarily e.g. vehicle battery under voltage. The
lamp is therefore turned off when the DTC demotion condition occurs.
System Fault
1. General Function
A. The system monitors a number of inputs across time in order to determine that a fault exists.
B. Faults are prioritized according to which has the most likely cause.
C. Maximum fault store is equal to 15.
D. Certain faults are not covered through DTC. The main ones are:
1) Sensor thermal shutdown (over 257°F/125°C).
2) Ignition Line stuck ; requires observation of lamps at Ignition ON to diagnose.

Description and Operation

Description

1. Mode
(1) Configuration State
A. All sensors should be in the Low Line (Base) state.
B. In Low Line (Base) configuration, sensor transmissions occur every 3 minutes 20 seconds
(nominal) and pressure is measured every 20 seconds.
(2) Normal Fixed Base State
A. Sensor transmissions continue at the Low Line (Base) configuration defined rates until the
state is either changed by LF command or by the sensor detecting a condition that requires
a temporary change to another state.
B. The LF command to this state must contain the sensors ID.
(3) Storage Auto State:
A. This state is a Low current consumption state.
B. Sensors are in this state when they first arrive at the dealership (either on the vehicle or as
replacement spares).
C. In this state, the sensor does not measure pressure / temperature / battery level.
D. The sensor will not transmit in this state unless requested to do so by the initiate command.
(4) Alert State:
A. The sensor automatically enters this state if the measured temperature exceeds
230 °F(110 °C) and over temperature shutdown is likely.
B. In this state, pressure is measured every 4 seconds and RF data transmitted every 4
seconds.
C. The state lasts for 1 minute if it is pressure triggered.
D. This state is alse entered when a 3 psi change in pressure from the last RF transmission
 occurs.

Sensor mode is used to configure sensor between high line and low line system. TPM
sensor for MD should be set to low line.

Removal

Tire Removal
1. Deflate tire & remove balance weights.

Sensor can be unscrewed before unseating the tire bead.

• The tire bead should be broken approx. 90° from the valve side of the wheel. The bead
breaker should not be set too deep.
• Avoid tire/tool contact with the valve on dismount.
• Dismount should end near the valve.
Sensor Removal

Handle the sensor with care.

1. Remove the valve nut.

The valve nut should not be re-used.

2. Discard the valve assembly.

Installation

Sensor Fit

• Handle the sensor with care.

• Avoid lubricant contact.
• Ensure that the wheel to be fitted is designed for sensor mount. There should normally be a
mark to indicate this.
• Ensure that the valve hole and mating face of the wheel are clean.
1. Slide the sensor-valve unit through the valve hole of the rim. Hold the sensor against the rim and
the rubber grommet against the sealing surface.
2. Insert the nut over the valve stem and then tighten the nut.
3. Continue to tightening the nut until contact with the rim and then tighten to 3.5 ~ 4.5Nm.

- Tighten slowly with quarter turn steps until the final torque is reached.
- Do not exceed allowed torque.
- Do not use electric or pneumatic tools.

4. Check that the sensor is firmly attached to the rim.

Risk of damage during the tire installation/ removal if the sensor is not firmly attached to the
rim.

5 Carry out inflation / pressure correction and then fit valve cap.
.

Change the newly installed sensor mode to Normal Fixed Base(Low Line) with the 'GDS'.
Mode (Status / option) of the sensor installed to the vehicle should be Normal Fixed Base
(Low).

Description and Operation

Description

1. 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 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 learning is enabled.
(3) Test State
A. This state is only used in manufacturing plant to check RF transmission between sensor and
receiver.

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, 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
A. Auto-learn takes place only once per Ignition cycle.
B. On successful completion, 4 road wheel sensor ID's are latched into memory for monitoring.
C. Until Auto-learn completes, previously learned sensors are monitored for under inflation / leak
warnings.
2. General Conditions to Learn New Sensors:
A. Receiver must determine that it is confident that sensor is not temporary:
1) Uses vehicle speed.
2) Uses confidence reduction of previously learned sensors.
B. Typical time at driving continuously over 12.4 mph(20 kph) to learn a new sensor is up to 20
minutes.
3. General Conditions to Un-Learn a sensor that is removed:
A. It takes less than 20 minutes at 12.4 ~ 18.6 mph(20 ~ 30kph).
B. Confidence reduction is dependent on time which vehicle is driven at speed greater than or
equal to 12.4 mph(20 kph).

Replacement

When the receiver first arrives for replacement:

1) It will be in Virgin State.
 2) It will not be configured for any specific platform.
3) It will not have any sensor ID's memorized.

It is important to make sure that the correct receiver is used to replace the faulty part i.e. it must be
Low Line and not High Line in order to have the correct inflation warning thresholds set.

1. Disconnect vehicle battery.

2. Remove the glove box.
(Refer to BD group - " Crash Pad")
3. Remove faulty part and fit bracket assembly to new part.

4. Secure new part to vehicle and fit connector.

5. Re-connect battery and turn Ignition on.
6 Check that TREAD Lamp flash rate matches Virgin State indication.
