In this video, I'll show you what causes the C1A00-54 code and red suspension light on the dash, and the basics for fixing it.
After taking your air suspension-equipped Land Rover to a garage that isn't familiar with these vehicles (or doing the suspension calibration yourself using third-party diagnostic tools), you might find the Ride Level Control is inoperable, with a red light on the instrument cluster and the height buttons beeping every time you push them. This is common and usually quite easy to fix as the ride level module is in the 'Calibration' or "Manufacturing / freeze mode' state. Either state will cause this, and the way to fix both conditions is basically the same.
Frequently asked questions:
What diagnostic tool do you use?
- I use a ThinkDiag, you can buy it from the ThinkCar website. I run it on both an iPhone and (in this video) an Android phone. I also occasionally run it on an Android tablet -- which they don't want you to do because ThinkCar want to sell you their professional series devices -- though unless your tablet is cellular data-capable or you are doing the work somewhere that you have a good WiFi connection, I would just use it on your phone.
My problem didn't go away! My problem is [insert problem / trouble code]! Help?
- I can't. I'm not a mechanic, I'm just some hobbyist DIY nerd who figured this out on his own to fix his own vehicle. If your problem keeps coming back, then it is probably something else, possibly the RLC module itself. But that's a problem for you to investigate and solve, or go to a Land Rover specialist if you have run out of ideas.
