What Does C1910 Mean?
The ride control module has detected an open circuit in the right front shock actuator control circuit. A complete break exists in the wiring or connector, preventing the module from controlling the RF damper solenoid.
Common Causes
35%
Broken wire in the RF shock actuator harness from engine bay heat degradation or vibration fatigue
30%
Disconnected or backed-out terminal at the actuator connector
25%
Open solenoid coil inside the RF shock actuator
10%
Terminal corrosion creating high resistance at contact surfaces
Diagnostic Steps
1
Step 1: Check the RF shock actuator connector for disconnection. Ensure full engagement and lock tab closure.
2
Step 2: Measure solenoid resistance at the connector. OL confirms internal actuator failure.
3
Step 3: Test wire continuity from actuator connector to ride control module connector.
4
Step 4: Inspect the harness near the shock tower, strut mount, and engine bay routing for heat damage or abrasion.
5
Step 5: Repair opens with proper sealed connections and verify actuator operation.
Estimated Repair Cost
$150 - $850
Parts + labor, varies by vehicle and location
The ride control module has detected an open circuit in the right front shock actuator control circuit. A complete break exists in the wiring or connector, preventing the module from controlling the RF damper solenoid.
The most common cause of C1910 (Ride Control RF Shock Actuator Circuit Open) is: Broken wire in the RF shock actuator harness from engine bay heat degradation or vibration fatigue
Typical repair costs for C1910 range from $150 to $850, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The RF damper operates in a fixed default mode, causing front-end damping asymmetry that may affect steering response and braking stability.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1910 to identify the root cause.
