Applicability

Introduction

2012 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 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 and the system initialized according to the procedure in this bulletin.

Warranty Information

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.

Activation Procedure

1. Connect TIS Techstream.





2. Cycle the ignition switch to the "IG-ON" position and check that the Low Tire Pressure Warning Light flashes for 1 minute and then remains illuminated.





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

4. Using TIS 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.





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.





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.

3. Cycle the ignition "OFF" and then to "IG-ON"

4. Check the tire pressure values of all the tires using TIS Techstream.
