What Does C1914 Mean?
The ride control module has detected an open circuit in the left front shock actuator control circuit. There is a complete electrical break preventing solenoid energization at the LF corner, locking the damper in its default state.
Common Causes
35%
Broken wire in the LF shock actuator harness from engine bay heat degradation or vibration
30%
Disconnected terminal at the actuator or module connector
25%
Internal open solenoid coil in the LF shock actuator
10%
Corroded terminal contacts creating open circuit condition
Diagnostic Steps
1
Step 1: Check the LF actuator connector for disconnection and proper seating.
2
Step 2: Measure solenoid resistance at the connector. OL confirms internal failure.
3
Step 3: Test wire continuity from actuator to module to isolate the open.
4
Step 4: Inspect the harness near the strut tower and engine bay for heat damage, abrasion, or rodent damage.
5
Step 5: Repair with sealed connections and verify actuator responds to module commands.
Estimated Repair Cost
$150 - $850
Parts + labor, varies by vehicle and location
The ride control module has detected an open circuit in the left front shock actuator control circuit. There is a complete electrical break preventing solenoid energization at the LF corner, locking the damper in its default state.
The most common cause of C1914 (Ride Control LF Shock Actuator Circuit Open) is: Broken wire in the LF shock actuator harness from engine bay heat degradation or vibration
Typical repair costs for C1914 range from $150 to $850, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The LF damper operates in fixed default mode, causing front damping asymmetry that may affect steering precision and ride comfort on the driver side.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1914 to identify the root cause.
