ADDITIONAL INFORMATION
Introduction
2016 model year CT 200h vehicles are equipped with a direct-type Tire Pressure Warning
System (TPWS). Each tire (except 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
and the system initialized according to the procedure in this bulletin.

Tire Pressure Warning System Activation & Initialization
Reference

After cycling the ignition to the “IG-ON”
position, the Low Tire Pressure Warning Light
will blink for 1 minute and then remain
illuminated until all the tire pressure warning
valves/sensors are activated.

The Diagnostic Trouble Codes (DTCs) listed
below are 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.

Tire Pressure Warning System Activation & Initialization
Activation Procedure (Continued)
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.
Figure 3.
NOTE
This operation is required for the system
to be activated and must be performed
for each tire (except the spare tire), one
at a time.

Core
4. Using Techstream, check for TPWS DTCs.
•
If NO DTCs are stored, go to step 1 of the initialization procedure.
•
If DTCs C2111 – C2114 are stored, repeat step 4.
HINT
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 and DTCs C2111 –
C2114 will be stored in the TPWS ECU.
NOTE
If DTCs C2111 – C2114 are present after repeating step 4, lift the vehicle and turn each tire 90
to 270 degrees. Then repeat step 4.

Tire Pressure Warning System Activation & Initialization
Initialization Procedure
1. Adjust all tires (except the spare tire) to the
standard tire inflation pressure, as indicated
on the Tire and Loading Information label
located inside the vehicle.
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.
•
Figure 4.

Tire and Loading Information Label
Adjust the tire pressure when the tires
are cold.
2. Push and hold the Tire Pressure Warning
"SET" switch until the Low Tire Pressure
Warning light blinks 3 times and then turns
OFF to set the tire pressure initialization.
Figure 5.
NOTE
It is necessary for the ignition to be in the
"IG-ON" mode AT LEAST 5 minutes for the
initialization to complete correctly
3. Cycle the ignition “OFF” and then to “IG-ON”.
4. Check the tire pressure values of all the tires using Techstream.
TPWS ECU / DATA LIST / TIREPRESS 1–4
NOTE
• It can take 2 – 3 minutes for the tire pressure values to be displayed on the
Techstream Data List.
•
If the tire pressures values CANNOT be displayed on the Techstream screen, the
initialization is NOT completed. Repeat steps 2 – 4.
