Description and operation
TREAD Lamp
| – |
Tire Under Inflation / Leak Warning.
|
| 1. |
Turn on condition
| • |
When tire pressure is below allowed threshold
|
| • |
When rapid leak is detected by the sensor.
|
| • |
Indicates that tire needs to be re-inflated to specified pressure
/ repaired.
|
|
| 2. |
Turn off condition
| • |
Under-inflation : When tire pressure is above [warning threshold
+ hysteresis].
|
| • |
Rapid Leak : When tire pressure is above [leak warning threshold].
|
|
DTC Warning
| 1. |
Turn on condition
| • |
When the system detects a fault outside the receiver/ sensor.
|
| • |
When the system detects a receiver fault.
|
| • |
When the system detects a sensor fault.
|
|
| 2. |
Turn off condition
| • |
If the fault is considered 'critical', then the lamp stays 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 driver's 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 stay on until DTC demotion
checking is completed.
|
| • |
'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.
|
|
| • |
When driving in high altitude grades, it is natural for the atmospheric
pressure to decrease. Therfore, please check the tire pressure and
add more air as necessary. Additionally required tire air pressure
per km above sea level : 1.5 psi/km
|
| • |
Tire pressure can be decreased naturally due to decrease in ambient
temperature (especially in winter). In this case, fill tires with
air to the specification if warning lamp is illuminated as this
is natural phenomenon.
|
|
System Fault
| 1. |
General Function
| • |
The system monitors a number of inputs across time in order to
determine that a fault exists.
|
| • |
Faults are prioritized according to which has the most likely
cause.
|
| • |
Up to 15 faults can be saved.
|
| • |
Certain faults are not covered through DTC. These include:
|
| a. |
Sensor thermal shutdown (over 257°F/125°C).
|
| b. |
Stuck Ignition Line: requires observation of lamps at
Ignition ON to diagnose.
|
|
|
Troubleshooting
|
Find the inspection number by referring to the table above.
The following content is irrelevant of the inspection procedure.
|
| 1. |
Warning lamp types
| • |
Keeps on without blinking : Low pressure tire warning lamp
|
| • |
Flashes at 0.5 second intervals constantly : Initial state warning
lamp
|
| • |
Cluster blinks for 1 minute at 1 second intervals, then turns
ON : Error code warning lamp
|
|
Turn IG OFF and then IG ON again to check the warning light type.
|
|
| 2. |
(1) Check the warning lamp state.
| • |
Check the vehicle warning lamp state.
|
| • |
Check if the warning lamp state is caused by tire low pressure.
Symptom : Keeps on without blinking
|
|
| 3. |
(2) Check the warning lamp state.
| • |
Check the vehicle warning lamp state.
|
| • |
Check if the warning lamp state is caused by the initial state
(virgin mode) of TPMS receiver.
Symptom : Flashes at 0.5 second intervals constantly.
|
|
| 4. |
(3) Check the warning lamp state.
| • |
Check the vehicle warning lamp state.
|
| • |
Check if the warning lamp state is caused by error code (TPMS
receiver & TPMS sensor failure).
Symptom : Cluster blinks for 1 minute at 1 second intervals,
then turns ON.
|
|
| 5. |
Low tire pressure warning lamp
Cold : Vehicle kept for more than 60 minutes after stopping.
→ 0.07 kgf/cm² (1.0 psi) additional injection at the specified tire pressure.
Hot : Driven vehicle
→ 0.28 kgf/cm² (4.0 psi) additional injection at the specified tire pressure.
|
In case the warning lamp fails to turn OFF after injecting tire
pressure, disconnect the KDS/GDS and drive less than 1 km at 25
km/h.
|
|
| 6. |
Inspect initial state warning lamp
| A. |
TPMS warning lamp
(1) Check the TPMS warning lamp status.
(2)Flashes at 0.5 second intervals constantly. -> Initial state
warning lamp
|
Turn IG OFF and then IG ON again to check the warning
lamp type.
|
|
| B. |
Items to check in case of blinking warning lamp
(1) Enter sensor ID.
(Refer to TPMS Receiver - "Repair procedures")
(2) Enter vehicle name.
(Refer to TPMS Receiver - "Repair procedures")
(3) Enter VIN.
(Refer to TPMS Receiver - "Repair procedures")
(4) Change TPMS ECU mode (to Standard mode).
|
|
| 7. |
DTC checklist for performance test.
| •
|
Be sure to check DTC.
(Refer to DTC manual - "Tire Pressure Monitoring")
|
| •
|
If the TPMS warning light does not turn on : TPMS sensor
periodically learns the sensor through driving.
|
| •
|
If the TPMS warning light turns on : Replace TPMS sensor,
TPMS receiver.
