Title
TIRE PRESSURE WARNING SYSTEM ACTIVATION AND INITIALIZATION
Component
GENERAL INFORMATION
Models
'10 SC430
INTRODUCTION:
The 2010 model year SC 430 is equipped with a direct-type Tire Pressure Warning System (TPWS). Each wheel (except spare tire) has a tire pressure warning valve/sensor that measures tire pressure data. 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.
APPLICABILITY:
WARRANTY INFORMATION:
REQUIRED TOOLS & EQUIPMENT:
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 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. Check that the Tire Pressure Warning Select Switch is in the "MAIN" position.
2. Connect ETAS Techstream.
3. 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.
4. 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.
NOTE
This operation is required for the system to be activated and must be performed for each tire, (except spare tire) one at a time.
5. Using ETAS 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 rotate each tire so that the tire pressure warning valve/sensor is at the top of the wheel well (in the 12 o'clock position). Then repeat step 4.
INITIALIZATION PROCEDURE:
1. Adjust all tires 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 tire pressure correctly when outside temperature is significantly colder or warmer than shop temperature, please reference the Tire Inflation Pressure Compensation and Adjustment Service Bulletin (TSB#0642).
2. Push and hold the Tire Pressure Warning "SET" Switch for 3 seconds until the Low Tire Pressure Warning Light blinks 3 times and then turns OFF to begin the tire pressure initialization.
NOTE
It is necessary for the ignition to be in the "IG-ON" mode AT LEAST 5 minutes for initialization to complete correctly.
3. Cycle the ignition to the "OFF" position and then to the "IG-ON" position.
4. Check the tire pressure values of all the tires using ETAS 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 ETAS Techstream Data List.
- If the tire pressure values CANNOT be displayed on the ETAS Techstream screen, the initialization is NOT completed. Repeat steps 2 - 4.
