How to reset lexus gx470 air suspension

To reset the air suspension system on a Lexus GX470, begin by inspecting the system for potential issues like damaged air struts, faulty height sensors, leaks, or a malfunctioning air compressor. If there are underlying problems, repairs may be necessary before a reset will work.

Lexus gx470 air suspension reset: Turn off the ignition, remove the key, and disconnect the battery. Start by removing the negative terminal, followed by the positive terminal. Leave the battery disconnected for about 10-15 minutes to allow the system to reset.

Reconnect the battery by attaching the positive terminal first, then the negative. Securely tighten the connections and ensure they are clean. Start the vehicle and let it idle for a few minutes.

Locate the height control switch, typically found near the dashboard or center console. Toggle through the height settings ("High," "Normal," and "Low") and return to "Normal." Drive the vehicle slowly (under 15 mph) to allow the suspension system to recalibrate.

If the air suspension warning light remains on, use an OBD-II scanner to check and clear any diagnostic trouble codes. Persistent codes may require further troubleshooting.

Observe the vehicle's ride height to confirm proper adjustment. Listen for the compressor to engage—continuous operation may indicate a leak or another problem. If the system does not reset or continues to malfunction, seek assistance from a certified Lexus technician.
