C1932 — Air Suspension Front Compressor Relay Circuit Short To Ground

System: Chassis  |  Type: Manufacturer-Specific  |  Make: Generic

About C1932

C1932 is a manufacturer-specific chassis diagnostic trouble code. It belongs to the C-prefix family of codes, which covers chassis, braking, steering, suspension, or stability-control faults.

When C1932 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Chassis (C) codes are stored in the ABS, traction control, or stability-control modules. An enhanced or OEM-level scan tool is usually required to read and clear them.

C1932 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The air suspension system uses an electric compressor, energized through a relay commanded by the air suspension control module, to maintain vehicle ride height. DTC C1932 is set when the control module detects the front compressor relay control circuit shorted to ground, meaning the coil control circuit is grounded at a point other than the intended module switched path. This unwanted ground can energize the relay through an uncontrolled path or be read by the module as an out of range low condition. When this code is set, the compressor may behave erratically or fail to control ride height, ...
