What Does U0132 Mean?
The vehicle's control modules cannot communicate with the Ride Level Control Module, which manages air suspension or adaptive ride height systems. This network fault prevents proper suspension adjustments and ride height control.
Common Causes
35%
Failed ride level/air suspension control module
30%
Damaged wiring harness or corroded module connectors
20%
CAN bus circuit fault or communication line issue
10%
Power supply or ground circuit failure to suspension module
5%
Module programming error or software fault
Diagnostic Steps
1
Step 1: Verify ride level control module has proper power supply and ground using multimeter
2
Step 2: Inspect module connector for water damage, corrosion, or bent pins
3
Step 3: Check CAN bus voltage levels at module connector (both CAN-H and CAN-L lines)
4
Step 4: Test air suspension compressor operation and verify module can control suspension components
5
Step 5: Scan for multiple network codes indicating broader CAN bus issue versus isolated module failure
Estimated Repair Cost
$200 - $1,200
Parts + labor, varies by vehicle and location
The vehicle's control modules cannot communicate with the Ride Level Control Module, which manages air suspension or adaptive ride height systems. This network fault prevents proper suspension adjustments and ride height control.
The most common cause of U0132 (Lost Communication With Ride Level Control Module) is: Failed ride level/air suspension control module
Typical repair costs for U0132 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Suspension may remain at fixed height or drop to mechanical stops, affecting ride quality and ground clearance. Vehicle handling characteristics may change, and uneven ride height can affect headlight aim. Drive cautiously and avoid rough roads.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0132 to identify the root cause.
