What Does C1711 Mean?
The Road Sensing Suspension (RSS) module has detected that the left front damper actuator circuit is shorted to ground. The solenoid control circuit has an unintended path to chassis ground, which may cause the actuator to be permanently energized, de-energized, or drawing excessive current. The left front shock absorber will not respond to electronic control commands, and the ride control warning light will illuminate.
Common Causes
35%
Wiring harness chafing against a metal body or suspension component, grounding the control wire
25%
Internal solenoid coil short to the actuator housing (ground path through the damper body)
25%
Water intrusion at the damper connector causing a low-resistance ground path
15%
Corroded ground wire creating a feedback path through the signal circuit
Diagnostic Steps
1
Disconnect the left front damper actuator connector. Measure resistance between each solenoid pin and the actuator body (chassis ground) — should be infinite (open). A low reading indicates an internal short to ground.
2
With the actuator disconnected, check the control wire from the module to the actuator connector for continuity to ground — should be open. If continuity exists, there is a wire-to-chassis short in the harness.
3
Inspect the wiring harness routing, especially where it passes through the inner fender, near the strut tower, and along the suspension components. Look for abraded insulation against sharp metal edges.
4
Check the actuator connector for water pooling, corrosion, or contaminated terminals. Dry, clean, and apply dielectric grease.
5
If the solenoid and wiring test clean, command the damper actuator via the scan tool with a test load to verify the module's output driver is functioning correctly.
Estimated Repair Cost

The most common cause of C1711 (Left Front Damper Actuator Short Circuit to Ground) is: Wiring harness chafing against a metal body or suspension component, grounding the control wire
Typical repair costs for C1711 range from $150 to $750, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The left front damper is stuck in a fixed state. The vehicle is safe for moderate driving, but handling balance will be affected since the left front will not match the other corners' damping. Avoid high-speed driving and sudden lane changes. 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 C1711 to identify the root cause.
