U0132 Lost Communication with Ride Level Control Module
The Ride Level Control Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Air or electronic suspension levelling stops working. Typical causes are loss of power or ground at the module, an open or shorted CAN/LIN bus wire, a connector fault, or an internal module failure.
