ADDITIONAL INFORMATION

Introduction

2018 model year 4Runner 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,
and the measured tire pressure data is transmitted to the Tire Pressure Warning System
antenna/receiver 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.
*Limited grade ONLY.

Reference







AFTER cycling the ignition to the “IG-ON”
position, the Low Tire Pressure Warning Light
will blink for 1 minute and remain illuminated
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 DTCs will automatically clear when the
tire pressure warning valves/sensors
are activated.

Activation Procedure (Continued)

3. Press or remove the valve core to reduce the
tire inflation pressure rapidly by 6 psi
(0.4 kgf/cm2, 40kPa), or more, within
30 seconds.

Figure 3.

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.

4. Using Techstream, check for TPWS DTCs. If no DTCs are stored, continue to step 5. If DTCs
C2111 – C2115 are stored, repeat step 3.
5. Adjust ALL tires (including the spare tire) to
the standard tire inflation pressure as
indicated on the Tire and Loading Information
label located inside the driver's door jamb.

NOTE
To adjust the tire pressure correctly when
the 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.
