Lost Communication With Ride Level Control Module
- Severity
- Medium
- Driving
- Drivable — book it in
The control module has stopped receiving messages from the ride level control module, which controls air suspension or adaptive damping. The suspension will fall back to whatever its failure position is. On an air-sprung vehicle that can mean the car settling overnight until it is sitting on its bump stops, which is uncomfortable, damaging, and unpleasant to drive on a rough road.
Possible causes
- CommonLow battery voltage or a discharged battery, dropping modules off the bus
- CommonBlown fuse or corroded earth on the supply to the ride level control module
- CommonWater ingress - these modules are often mounted low or in a wheel arch
- CommonDamaged, chafed or corroded bus wiring
- PossibleFailed module
- PossibleModule not configured after suspension work
What you might notice
- Vehicle sitting low, or at an uneven height
- Suspension warning message
- Ride height not adjusting
- Harsh ride, or the car crashing over bumps
- Compressor running constantly or not at all
What to check, in order
- Check the ride height at all four corners. A car sitting on its bump stops should be driven gently and slowly to be repaired, not driven normally.
- Check battery voltage and state of charge before anything else. A weak or failing battery drops modules off the bus and sets lost-communication codes with no wiring fault at all - this is the single most common false lead in this whole family.
- Check the fuses, earths and connector for the ride level control module, and look for water at the module.
- Check for other suspension codes. An air leak or a failed compressor produces its own codes and is a different fault to this one.
- Note that headlamp aim is affected by ride height on many vehicles, so a car sitting wrong may also be dazzling oncoming drivers.
Read this code from your own car
Plug an ELM327 adapter into the OBD-II port under the dashboard. Pin16 reads every stored, pending and permanent code, explains each one like this page does — offline, with no account — and shows what the car recorded when the fault was set.
