C0575 on 2009-2014 Cadillac CTS-V — Left Front Shock Absorber Actuator Circuit
1 vehicles · 1 makes
Most Reported On
C0575 is an OBD-II diagnostic trouble code meaning “Left Front Shock Absorber Actuator Circuit.” A General Motors chassis code (Chevrolet, GMC, Cadillac and Buick applications with electronically controlled suspension - Autoride, MagneRide, or Real Time Damping). The suspension control module commands variable current to each shock absorber actuator using pulse-width modulation and continuously measures actual current; when the measured current deviates from the commanded value at the left front corner, this code sets. The system usually defaults to a fixed damping setting, so the car remains drivable but rides firmly or harshly. Sub-codes narrow it down: :01 short to battery, :02 short to ground, :04 open circuit. This code is most commonly reported on 2009-2014 Cadillac CTS-V.
Common Causes
Diagnostic Tools
This is a chassis code. A basic engine-code reader will not show it — you need a scanner that reads chassis modules. These read C0575.
One caveat that applies to every scanner: only powertrain codes are standardised across manufacturers. Body, chassis and network coverage is "enhanced" diagnostics, and how deep it goes varies by make and model year — check your specific vehicle against the tool's coverage list before buying.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
