What Does C1911 Mean?
The ride control module has detected a short-to-battery condition in the right front shock actuator circuit. An external voltage is feeding the control wire, causing uncontrolled solenoid operation at the RF corner.
Common Causes
40%
Chafed control wire contacting a power wire in the engine bay harness
25%
Internal solenoid short between coil winding and power terminal
25%
Connector contamination bridging control to power pins from engine bay fluids
10%
Module output driver fault on the RF channel
Diagnostic Steps
1
Step 1: Disconnect the RF actuator and check for voltage on the control wire (key on). Voltage present with actuator disconnected confirms a wiring or module fault.
2
Step 2: Measure resistance from control wire to B+ to identify the short source.
3
Step 3: Inspect the harness near the strut tower, engine, and any aftermarket installations for chafing.
4
Step 4: Check the connector for fluid contamination (oil, coolant, or brake fluid) bridging terminals.
5
Step 5: Repair the short and verify proper module control of all damping modes.
Estimated Repair Cost
$150 - $850
Parts + labor, varies by vehicle and location
The ride control module has detected a short-to-battery condition in the right front shock actuator circuit. An external voltage is feeding the control wire, causing uncontrolled solenoid operation at the RF corner.
The most common cause of C1911 (Ride Control RF Shock Actuator Circuit Short To Battery) is: Chafed control wire contacting a power wire in the engine bay harness
Typical repair costs for C1911 range from $150 to $850, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Constant solenoid energization at the RF corner locks damping in one mode, affecting front-end balance during steering inputs and braking.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1911 to identify the root cause.
