ADDITIONAL INFORMATION

Introduction

2014 model year LS 460 and LS 600h vehicles are equipped with a direct-type Tire Pressure
Warning System (TPWS). Each tire (including the spare tire) has a tire pressure warning
valve/sensor that measures tire pressure. The data is transmitted to the Tire Pressure Warning
System antenna/receiver and then to the Tire Pressure Warning System ECU.
During Pre-Delivery Service (PDS), the tire pressure warning valves/sensors must be activated
according to the procedure in this bulletin.

Tire Pressure Warning System Activation & Initialization

Reference
• After cycling the ignition to the “IG-ON”

Figure 1.

mode, the Low Tire Pressure Warning Light
will blink until all the tire pressure warning
valves/sensors are activated.
• The Diagnostic Trouble Codes (DTCs) listed

below may be stored in the TPWS ECU until
the tire pressure warning valves/sensors
are activated.
• The multi-information display will read

“Check Tire Pressure System” until all
tire pressure warning values/sensors
are activated.
• The DTCs will automatically clear when

the tire pressure warning valves/sensors
are activated.

Tire Pressure Warning System Activation & Initialization

Activation Procedure

1. Connect Techstream.
2. Cycle the ignition switch to the “IG-ON” mode and
check that the Low Tire Pressure Warning Light
blinks for 1 minute and then remains illuminated.

Figure 2..

NOTE
“Check Tire Pressure System” is displayed
on the multi-information display until all tire
pressure warning valve/sensors are activated.

3. Press or remove the valve core to reduce the tire
inflation pressure rapidly by 6 psi (0.4 kgf/cm2,
40 kPa), or more, within 30 seconds.
If the tire inflation pressure is NOT reduced
by 6 psi (0.4 kgf/cm2, 40 kPa), or more,
within 30 seconds, the tire pressure warning
valves/sensors will NOT be activated.

NOTE
This operation is required for the system to be
activated and MUST be performed for each tire
(including the spare tire), one at a time.

Tire Pressure Warning System Activation & Initialization

Activation Procedure (Continued)

4. Check that the Low Tire Pressure Warning Light goes OFF after all the tire pressure warning
valves/sensors are activated.
5. Using Techstream, check for TPWS DTCs.
• If NO DTCs are stored, go to step 6.
• If DTCs C2111 – C2115 are stored, repeat step 3.
• If any other DTCs are stored, refer to the Repair Manual.
6. Press the “DISP” switch on the steering wheel
and check that the tire pressures are displayed on
the multi-information display.

Figure 4..

NOTE
• The tire pressure display is NOT
shown until all tire pressure warning
valves/sensors are activated.
• If “Check Tire Pressure System” or
“CHECKING” (which means the tire
pressures are being measured) is
displayed, repeat step 3. If step 3 is
performed and the tire pressures are
still NOT displayed, turn the tires 90 to
270 degrees.
• If the above steps are performed and
the multi-information display does NOT
show the tire pressures, refer to the
Repair Manual.

Tire Pressure Warning System Activation & Initialization

Initialization Procedure

1. Adjust all tires (including the spare tire) to the
standard tire inflation pressure, as indicated on
the Tire and Loading Information Label located
in the vehicle.

Figure 5..

NOTE
• To adjust tire pressure correctly when
outside temperature is significantly colder
than shop temperature, perform a Health
Check using Techstream and select the
“Compensation Tire Pressure” checkbox.
Compensation pressures will be displayed
on the Health Check results screen.
• Adjust the tire pressure when the tires
are cold.

2. Cycle the ignition switch to the “IG-ON” mode and
then push and hold the Tire Pressure Warning
“SET” switch for 3 seconds until the Low Tire
Pressure Warning Light blinks 3 times and then
turns OFF to set the tire pressure initialization.

Initialization Procedure (Continued)

4. Check that the tire pressures for all 5 tires are
displayed on the multi-information display.

Figure 7..

If the tire pressure values are NOT displayed on
the multi-information display, the initialization is
NOT complete. Repeat steps 2 – 4.
TIRE PRESSURE

NOTE
• Check that the tire pressure adjusted in
step 1 is displayed.
• Initialization will be completed if signals
are received from all 5 tires. It takes 2 to 3
minutes to display the tire pressure data.
