Title:
TIRE PRESSURE WARNING SYSTEM INITIALIZATION

Component
GENERAL INFORMATION

Models
'10 Matrix

INTRODUCTION:
The 2010 model year Matrix is equipped with a direct-type Tire Pressure Warning System (TPWS). Each tire (except 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 initialized according to the procedure in this TSB.

NOTE:
The Tire Pressure Warning System valves/sensors are activated at the manufacturing plant. Only the initialization process is required during PDS.







APPLICABLE VEHICLES:







REQUIRED SSTs:

NOTE:
- Additional Techstream units may be ordered by completing the order form on ETAS and faxing it to (416) 431-8342.







WARRANTY INFORMATION:

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 on the vehicle.

NOTE
Adjust the tire pressure when the tires are cold

NOTE
To adjust tire pressure correctly when outside temperature is significantly colder or warmer than shop temperature. Follow the procedures outlined in the Tire Inflation Pressure Compensation and Adjustment service bulletin. (TSB1317)







2. Cycle the ignition switch to the "ON" position and check that the Low Tire Pressure Warning Light is OFF.







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 "ON" position for AT LEAST 7 minutes for initialization to complete.







IMPORTANT:
Initialization will NOT complete if the ignition switch is NOT left in the "ON" position for AT LEAST 7 minutes.

4. Cycle the ignition switch to the "OFF" position and then to the "IG-ON" position.
5. Connect ETAS Techstream to DLC3.
6. Select the Tire Pressure Warning System Data List.
TPWS ECU / DATA LIST / TIREPRESS 1 - 4
7. Confirm that each tire pressure on the ETAS Techstream Data List shows the set value from step 1.
- If the tire pressure is correct, initialization is complete.
- If the tire pressure is incorrect, check the tire pressure gauge and repeat steps 1 - 7.
