What it means

The ride level control module runs the air suspension or self-leveling suspension, keeping ride height steady as the load changes. This code sets when messages from this module stop reaching the network, so automatic height control stops. The car may stay at its current height or slowly sink if the system also has an air leak.

Symptoms5

Suspension warning light or message.
Raise and lower buttons do not respond.
Car leaning or one corner sitting low after being parked.
Unusually firm or soft ride on vehicles with adjustable damping.
Stability light on in some vehicles.

Possible causes6

Blown module power fuse.
Weak battery or low voltage.
Corrosion or water in the module connector, especially when it sits in the trunk or near the floor.
Poor ground connection.
Open or shorted CAN wiring to the module.
Internal module failure.

How to diagnose5

Find the module location in the service information, as it varies widely between vehicles.
Try to connect to the module with a scan tool; if it does not respond, check its fuse, power and ground.
Inspect the module connector and mounting area for water or corrosion.
Check the CAN lines to the module and compare their resistance with the manufacturer specification.
If the car is sinking, check the air system for leaks, since that is a separate problem that can accompany this code.

How to fix5

Replace the blown fuse and charge or replace the battery.
Dry the module area, fix the water leak and clean the connector.
Repair damaged network wiring or grounds.
Replace the module if proven faulty, then program it and perform ride height calibration with a scan tool.
Clear the codes, test raising and lowering, and confirm the code does not return.

In Saudi riyals; the highlighted part is the expected range for this fault.

The cost is low for a fuse, connector or battery, and rises when the module must be replaced, programmed and height-calibrated.

Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions

Can I drive with this code?

Yes, carefully, if the ride height looks normal. If the car has dropped a lot or leans clearly, avoid long trips, because the tires can rub the body and handling suffers.

Is the problem in the air springs?

Not necessarily. This code is about the control module's network link. Leaking air springs or a weak compressor show their own symptoms and codes.

This guide is for information only and does not replace an inspection by a qualified technician. If the fault involves brakes, steering, engine temperature, electrics or refrigerant, do not attempt the repair yourself.
