Introduction
The 2011 model year Matrix is 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 System must be initialized according to the procedure in this bulletin.
NOTE
The Tire Pressure Warning System valves/sensors are activated at the manufacturing plant. Only the initialization process is required during PDS.
Required Tools & Equipment
Additional Techstream units may be ordered by calling Approved Dealer Equipment (ADE).

Initialization Procedure
1. Cycle the ignition switch to the "IG-ON" mode and connect TIS techstream.
2. Adjust all tires (except the spare tire) to the standard tire inflation pressure as indicated on the Tire and Loading Information label on the vehicle.
NOTE
^ To adjust the tire pressure correctly when outside the temperature is significantly colder or warmer than shop temperature, follow the procedures outlined in the Tire Inflation Pressure Compensation and Adjustment service bulletin (T-SB-0345-08)
^ Adjust the tire pressure when the tires are cold.
3. Push and hold the Tire Pressure Warning "SET"
Switch until the Low Tire Pressure Warning Light
blinks 3 times and then turns OFF, indicating the
system initialization has begun.
The ignition switch MUST be left in the "IG-ON"
position for AT LEAST 7 minutes for initialization
to complete.
NOTE
Initialization will NOT complete if the ignition
switch is NOT left in the "IG-ON" position for
AT LEAST 7 minutes.
4. Cycle the ignition switch to the "OFF" position and then to the "IG-ON" position.
5. Check the tire pressure values of all the tires using TIS techstream.
NOTE
^ It can take 2 - 3 minutes for the tire pressure values to be displayed on the TIS techstream Data List.
^ If the tire pressure values CANNOT be displayed on the TIS techstream screen, the initialization is NOT completed. Repeat steps 2 - 4.
