The method to reset the air suspension system on a Lexus LS460 varies depending on the model year. Here's a guide based on common procedures:
2007-2012 Models (First-generation LS460 Air Suspension)
-
Restart the Vehicle and Check the Suspension System: Ensure the vehicle is on a flat surface and turn off the ignition. Wait approximately 5 minutes, then restart the engine. Check if the “Check Suspension” or similar warning light persists.
-
Manually Reset Suspension Height: Locate the air suspension control knob in the cabin and set it to "Normal" mode. If the suspension is still abnormal, switch to “High” or “Low” modes and then back to "Normal." The system may recalibrate automatically.
-
Battery Reset: Disconnect the negative battery terminal for 5-10 minutes and reconnect it. The system will reinitialize.
-
Reset Using an OBD Tool: Use an OBD-II diagnostic tool compatible with Lexus (e.g., Techstream). Access the air suspension system and perform a "Reset" or "Calibration."
2013-2017 Models (Facelifted LS460)
-
Check Suspension Mode Switch: Ensure the system is in “Normal” mode. If the error persists, toggle the suspension modes multiple times.
-
Initialize Height Sensors: Lift the vehicle so the wheels are off the ground, allowing height sensors to relax. Lower the vehicle and start the engine; the system should reinitialize the default height.
-
Techstream Calibration: Use Toyota’s Techstream software to access the air suspension control module. Perform “Initialize” or “Height Control Calibration.” Follow on-screen instructions to complete calibration.
2018+ Models (LS500 and LS500h with Air Suspension)
Newer models require more advanced diagnostic tools and procedures.
-
Automatic Reset via Driving: Drive the vehicle for a short distance, as the system may reset automatically. Avoid frequent or extreme suspension height adjustments.
-
Advanced Diagnostic Tools: Use professional diagnostic equipment (e.g., Techstream or Snap-on tools). Navigate to the suspension menu, clear any error codes, and perform a height calibration.
