Allion Air Suspension Failure
Summary of the thread
A 2023 Toyota Allion hybrid is experiencing air suspension failure, indicated by a warning light and error message. The car won't lift and leans noticeably, with low beams at an odd angle. The issue may stem from a defective cable or plug connection affecting the compressor's power supply. Suggested solutions include checking for bad connections or corrosion, with a recommendation to seek professional diagnosis to confirm the problem and avoid unnecessary compressor replacement.

Thanks for the insight! The 'electric pump' explanation helps a lot. So, if it's just a bad connection, is there a way to confirm it before replacing the compressor? Any tips on how to test the cable or plug connection?

Glad I could help! Honestly, unless you're really comfortable with electrical testing, I'd advise against poking around too much. These systems can be sensitive. The best bet is to get it to a workshop that knows air suspension. They can properly diagnose the connection with the right tools and tell you for sure if the compressor is gone. In my case, it was corrosion inside the connector that stopped the current. The workshop changed the connector and everything was working again. They charged me 95€ for that.

Okay, I understand. I'll take it to a workshop for a proper diagnosis. Knowing your experience with a similar connector issue gives me hope it won't be a full compressor replacement! Appreciate the help!

Hey there! I drive an older Toyota Allion myself, though not a hybrid, and I had a similar issue a while back. The leaning and the ride height problems are definitely signs of air suspension trouble. You mentioned a possible defective cable or plug connection, and that's a very likely cause. The air suspension system relies on a compressor, which is basically an electric pump that inflates the air springs. If the compressor isn't getting power due to a bad connection, it won't be able to maintain the correct ride height.
