| Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: INITIALIZATION (2008 LX570) | ||
INITIALIZATION
1. DESCRIPTION OF INITIALIZATION
(a) Perform initialization in the following cases:
- Before delivery of a new vehicle.
- After replacement of the tire pressure warning ECU.*
- After replacement of a tire pressure warning valve and transmitter.*
- Specified tire pressure changes depending on the size or type of tire.
- Changing the standard tire inflation pressure value due to trailer towing.
HINT:
*: Perform initialization after the transmitter ID registration is completed
.
(b) Before initialization
(1) Set the tire pressure of all tires to the specified value(s)
.
NOTICE:
Make sure the tires are cooled down.
2. INITIALIZATION PROCEDURE
(a) Turn the engine switch on (IG).
(b) Press and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.
(c) Turn the engine switch off.
(d) Connect the Techstream to the DLC3.
(e) Turn the engine switch on (IG) and turn the Techstream on.
(f) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(g) Check that the initialization has been completed.
(h) Confirm that the tire pressure data of all tires is displayed on the Techstream screen.
NOTICE:
- The initialization is normally completed within 2 to 3 minutes.
- If the initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 8 km/h (5 mph) or more continues for 20 minutes or more.
- While in test mode, the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.
-
The initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3.

ID1 Tire Inflation Pressure |
ID1 tire inflation pressure/ min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (gauge) / -100 kPa (-1.0 kgf/cm2, -14 psi) max.: Absolute pressure (abs) / 637.5 kPa (6.5 kgf/cm2, 92.5 psi), Relative pressure (gauge) / 537.5 kPa (5.4 kgf/cm2, 78 psi) |
Actual tire inflation pressure |
If 0 kPa (0 kgf/cm2, 0 psi) is displayed for the absolute pressure (abs) or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for the relative pressure (gauge), the data has not been received.* |

Actual tire inflation pressure |
If 0 kPa (0 kgf/cm2, 0 psi) is displayed for the absolute pressure (abs) or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for the relative pressure (gauge), the data has not been received.* |
|

Actual tire inflation pressure |
If 0 kPa (0 kgf/cm2, 0 psi) is displayed for the absolute pressure (abs) or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for the relative pressure (gauge), the data has not been received.* |
|
ID4 Tire Inflation Pressure |

Actual tire inflation pressure |
If 0 kPa (0 kgf/cm2, 0 psi) is displayed for the absolute pressure (abs) or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for the relative pressure (gauge), the data has not been received.* |
|
ID5 Tire Inflation Pressure |
ID5 tire inflation pressure/ min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (gauge) / -100 kPa (-1.0 kgf/cm2, -14 psi) max.: Absolute pressure (abs) / 637.5 kPa (6.5 kgf/cm2, 92.5 psi), Relative pressure (gauge) / 537.5 kPa (5.4 kgf/cm2, 78 psi) |
Actual tire inflation pressure |
If 0 kPa (0 kgf/cm2, 0 psi) is displayed for the absolute pressure (abs) or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for the relative pressure (gauge), the data has not been received.* |
HINT:
- The initialization is complete when the Data List "ID Tire Inflation Pressure" display shows the correct pressures.
-
*: It may take about 2 or 3 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2125/25
.
3. INITIALIZATION PROCEDURE (MULTI-INFORMATION DISPLAY)
(a) Turn the engine switch on (IG).
(b) Press and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.
HINT:
-
The initialization can be confirmed through the multi-information display.
- The order in which the data is received is random.
- If the signals from all the wheels are received, the initialization is complete.
-
It may take about 2 or 3 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2125/25
.
NOTICE:
- If the initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 8 km/h (5 mph) or more continues for 20 minutes or more.
-
The initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3.
- While in test mode, the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.
