U0132 Code: Lost Communication With Ride Level Control Module

on

What Is U0132 Code?

The U0132 code is an OBD-II communication fault code that indicates a lost connection between the vehicle control modules and the Ride Level Control Module. This module controls or monitors the vehicle suspension height system and communicates with other modules through the CAN network.

Code Description

U0132 means that one or more control modules have stopped communicating with the Ride Level Control Module. The failure usually occurs because of a CAN bus communication problem, electrical issue, or a faulty control module.

Vehicles Affected by U0132 Code

U0132 may appear on vehicles equipped with electronic suspension or automatic ride height control systems, including:

  • Land Rover
  • Range Rover
  • Mercedes-Benz
  • BMW
  • Audi
  • Volkswagen
  • General Motors vehicles
  • Ford vehicles
  • Jeep vehicles
  • Luxury SUVs with air suspension systems

The exact module name and repair procedure depend on the vehicle manufacturer and suspension design.

Systems Involved

  • Ride Level Control Module
  • Electronic Air Suspension System
  • Air Compressor System
  • Height Sensors
  • CAN Communication Network
  • Body Control Module

Common Symptoms

  • Suspension warning light
  • Vehicle height adjustment failure
  • Uneven vehicle ride height
  • Air suspension disabled message
  • Hard or uncomfortable ride
  • Scan tool cannot communicate with suspension module

Possible Causes

  • Faulty Ride Level Control Module
  • Damaged CAN High or CAN Low wiring
  • Loose or corroded connectors
  • Low battery voltage
  • Blown suspension module fuse
  • Faulty ride height sensors
  • Water damage inside electrical connectors

How Serious Is It?

Severity: Moderate to High

U0132 can affect electronic suspension operation. The vehicle may still drive, but ride height control and suspension comfort features may not work correctly.

Diagnostic Steps

  1. Scan all control modules and record all communication codes.
  2. Check battery voltage and charging system condition.
  3. Inspect Ride Level Control Module connectors.
  4. Check CAN wiring for open circuits or shorts.
  5. Verify module power and ground circuits.
  6. Check suspension height sensor data using a scan tool.
  7. Perform calibration after repairs if required.

Common Repair Mistakes

  • Replacing the suspension module without checking CAN communication.
  • Ignoring low voltage problems.
  • Replacing air suspension parts when the real issue is electrical.
  • Failing to calibrate ride height after repairs.

Common Repairs

  • Repair CAN communication wiring
  • Replace damaged connectors
  • Repair power and ground circuits
  • Replace Ride Level Control Module
  • Replace faulty height sensors
  • Perform suspension calibration

Repair Cost

Repair Estimated Cost
CAN wiring repair $50 - $250
Connector repair $50 - $150
Height sensor replacement $150 - $500
Ride Level Control Module replacement $500 - $1500

FAQ

Can I drive with U0132 code?

The vehicle may be driven, but suspension height control and comfort features may be affected.

What causes U0132 code?

Common causes include CAN network faults, wiring damage, low voltage, or a failed ride level control module.

Does replacing the suspension module fix U0132?

Only after confirming that the module has failed. Electrical testing should be completed first.

How do I fix U0132?

Diagnose the CAN network, repair wiring or power issues, and program the module if replacement is needed.
