What Does C1432 Mean?
The left rear damper solenoid circuit has a short to ground. The suspension control module detects that the damper control signal is being pulled low to ground potential, which prevents the module from properly controlling the damper's firmness. The left rear corner will default to its failsafe damping rate, and the driver may notice a harsh or unbalanced ride along with the suspension warning indicator.
Common Causes
35%
Wiring harness chafed against body or suspension metal, grounding the signal wire
30%
Left rear damper solenoid with internal short to ground/housing
20%
Water intrusion at the damper connector creating a ground path through corrosion
10%
Pinched or crushed wire at a grommet or frame pass-through
5%
Suspension control module internal ground fault on the output driver
Diagnostic Steps
1
Disconnect the left rear damper connector and check for continuity between each damper wire and chassis ground on the harness side — any continuity indicates the short is in the wiring.
2
With the connector disconnected, measure the solenoid coil resistance and check for continuity between each solenoid terminal and the damper body/mounting bracket — continuity indicates an internal short in the solenoid.
3
Inspect the wiring harness routing along the left rear suspension arm, frame rail, and wheel well for areas where the insulation may be worn through from contact with metal edges.
4
Check the body grommet where the harness passes from the underside into the body for pinched or cut wires.
5
If the short is not in the wiring or damper, disconnect the suspension module connector and recheck — if the short persists on the module-side harness, the module output driver is shorted.

The most common cause of C1432 (Damper LR Circuit Short to Ground) is: Wiring harness chafed against body or suspension metal, grounding the signal wire
Typical repair costs for C1432 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle can be driven at reduced speeds, but the left rear suspension damping is not being actively controlled. This creates an asymmetric handling condition that is most noticeable during turns and emergency maneuvers. Schedule repair promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1432 to identify the root cause.
