U0132

Lost Communication With Suspension Control Module A

Communication network (suspension) Generic OBD-II Low

What it means

U0132 means the network has lost communication with the suspension (ride-control) module, which manages adaptive damping or air suspension. With it offline the suspension falls back to a default setting, so the ride may feel harsher or, on air systems, the height may not adjust. The car remains safe to drive normally while the wiring, power, or module fault is repaired.

Low

Can I keep driving? Yes — the suspension defaults to a fixed setting. Ride quality or height may be off, but the car drives normally while you get it fixed.

Scan all modules and confirm the suspension module is offline.

Test the CAN bus lines to the module for open or short.
If wiring and power are good, replace the module, clear the code, and confirm the suspension responds.
