APPLICABILITY:
INTRODUCTION:
2012 model year GX460 vehicles are equipped with a direct-type Tire Pressure Warning System (TPWS). Each tire (including the 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 according to the procedure in this TSB
WARRANTY INFORMATION:
REQUIRED SSTs:
REFERENCE:
- After cycling the ignition to the "IG-ON" position, the Low Tire Pressure Warning Light will blink until all the tire pressure warning valves/sensors are activated.
- The Diagnostic Trouble Codes (DTCs) listed may be 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 ETAS 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/cm2, 40kPa), or more, within 30 seconds.
If the tire inflation pressure is NOT reduced by 6 psi (0.4 kgf/cm2, 40kPa), or more, within 30 seconds, the tire pressure warning valves/sensors will NOT be activated.
NOTE
This operation is required for the system to be activated and MUST be performed for each tire (including the spare tire) one at a time.
4. Using ETAS Techstream, check for TPWS DTCs.
- NO DTCs are stored, go to step 5.
- If DTCs C2111 - C2115 are stored, repeat step 3.
5. Adjust all tires (including the spare tire) to the standard tire inflation pressure, as indicated on the Tire and Loading Information Label located inside the driver's door jamb. Confirm that the Low Tire Pressure Warning Light is OFF.
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 2978.
