Common Symptoms
- Service ride control message
- Front left corner rides harshly or too soft
- Uneven ride feel between corners
- Suspension warning light on
- Clunking noise from front left suspension
Probable Causes (Ranked by Likelihood)
- Failed front left active shock solenoid valve Very High
- Corroded connector at the shock absorber High
- Damaged wiring running to front left shock Moderate
- Front left active shock absorber internal failure Moderate
- Suspension control module output driver failure Low
Step-by-Step Diagnostic Procedure
-
Scan for DTCs and check which corner is faulting
-
Inspect the front left shock connector for corrosion or water damage
-
Test solenoid resistance at the shock connector -- compare to specifications
-
Check wiring from the shock up to the body harness for damage
-
Swap connectors between left and right front shocks to see if fault follows
Frequently Asked Questions
Can I replace just the solenoid on the shock?
On some active shocks, the solenoid valve is serviceable separately. On MagneRide shocks, the solenoid is part of the damper assembly and the entire shock must be replaced.
What does the solenoid do on an active shock?
The solenoid valve controls fluid flow inside the shock absorber to vary the damping force. The suspension module adjusts the solenoid in milliseconds to adapt ride firmness to current conditions.
Will a bad active shock damage other suspension parts?
A failed active shock that is too soft can cause excessive body movement, putting additional stress on stabilizer bar links, bushings, and other suspension components over time.
