C1916 is triggered when monitoring logic identifies an issue with Ride Control LF Shock Actuator Circuit Short To Ground affecting ABS/chassis dynamics and brake control.
C1916 Code: Meaning, Symptoms, Causes & Fix
Overview
Symptoms
- reduced stability control performance
- chassis warning indicator
- ABS/traction light on
Common causes
- Open circuit in wiring affecting ride control lf shock actuator circuit short to ground
- Broken terminal inside harness
- Connector pin damage/corrosion or harness stress near related components
How to diagnose C1916
- Confirm C1916 and capture freeze-frame data with a professional scan tool.
- Inspect wiring, connectors, and grounds related to ride control lf shock actuator circuit short to ground for obvious defects.
- Use a continuity test from module pin to component to identify opens/high resistance.
- Check for related DTCs to identify the root-cause chain before replacing parts.
- After repair, clear codes and confirm readiness monitors complete without recurrence.
Severity of code C1916
Moderate: This code is moderate severity: the vehicle may still operate, but fault progression can increase repair cost over time.
Can you drive with C1916?
Most vehicles can be driven short-term with C1916, but postpone heavy load/highway driving until repaired.
If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.
How to fix it (step-by-step)
- Repair obvious wiring/connector faults first to prevent repeat parts replacement.
- Address the root fault mode (open) in the ride control lf shock actuator circuit short to ground circuit/system.
- Apply the required relearn/adaptation procedure if specified by service information.
- Road-test and verify C1916 remains cleared under the conditions that originally set the code.
Fix options
- Repair open circuit and secure connector lock.
- Restore continuity and verify pin tension.
- Clear DTCs and verify with live data and completed drive cycle.
Typical repair cost
$240-$1200
Common mistakes when diagnosing C1916
- Replacing parts without verifying voltage, ground, and signal integrity first.
- Ignoring related stored/pending codes that indicate upstream faults.
- Skipping post-repair verification drive cycle and readiness checks.
C1916 in common vehicles
C1916 appears across makes such as Mazda, Subaru, Lexus, Jeep. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.
Frequently asked questions
What causes C1916?
C1916 is commonly set by open faults affecting ride control lf shock actuator circuit short to ground.
How much does it cost to fix C1916?
For C1916, repair costs are typically $240-$1200 depending on exact root cause, labor rates, and part quality.
Can I clear C1916 without repair?
You can clear C1916 temporarily, but the code usually returns until the underlying fault is corrected.
