What Does C1916 Mean?
The ride control module has detected a short-to-ground in the left front shock actuator circuit. The control wire is grounding out, preventing the module from controlling the LF damper solenoid. The shock defaults to its base damping setting.
Common Causes
40%
Control wire insulation abraded against the strut tower, subframe, or engine components at the LF corner
25%
Internal solenoid short to the shock absorber body
25%
Water intrusion into the actuator connector
10%
Pinched wire at a harness clip or body panel
Diagnostic Steps
1
Step 1: Disconnect the LF actuator and measure resistance from each wire to chassis ground. Below 10k ohms confirms a ground fault.
2
Step 2: Check solenoid resistance from each terminal to the shock body for internal shorts.
3
Step 3: Trace the harness from actuator to module, looking for insulation damage near metalwork.
4
Step 4: Inspect and clean the connector; apply dielectric grease.
5
Step 5: Repair the short, clear codes, and verify all four corners respond to damping commands.
Estimated Repair Cost
$150 - $850
Parts + labor, varies by vehicle and location
The ride control module has detected a short-to-ground in the left front shock actuator circuit. The control wire is grounding out, preventing the module from controlling the LF damper solenoid. The shock defaults to its base damping setting.
The most common cause of C1916 (Ride Control LF Shock Actuator Circuit Short To Ground) is: Control wire insulation abraded against the strut tower, subframe, or engine components at the LF corner
Typical repair costs for C1916 range from $150 to $850, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The LF damper is locked in default mode, causing front suspension asymmetry that may reduce steering precision and driver-side ride quality.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1916 to identify the root cause.
