OBD2 Code C1417: Right Shock Circuit Short to Ground
The C1417 code indicates a short-to-ground fault in the right front shock absorber circuit of the electronically controlled active suspension system (such as TEMS or Active Height Control). The suspension ECU continuously monitors the electrical signal from the right shock actuator or sensor. When it detects that the circuit voltage drops below the expected threshold due to a ground short, it sets this code. As a safety measure, the system may disable adaptive suspension control and default the shock to a fixed firm mode.
1. Commonly Affected Makes
2. Most Common Causes
- Short to ground in the wiring of the right shock actuator
- Corroded, damaged, or bent pins in the right shock connector
- Internal short circuit in the right shock actuator or solenoid
- Faulty suspension control ECU (internal circuit driver failure)
- Issues in the main wiring harness to the suspension ECU
3. Symptoms You Will Notice
- Check Engine Light or Suspension Warning Light illuminated
- Suspension feels stiff or unresponsive, especially on the right side
- Loss of adaptive damping or ride height control
- Vehicle may ride unevenly or handle poorly
4. Step-by-Step Diagnosis
Scan for additional codes and verify C1417 is present
Visually inspect the right shock wiring and connector for damage, corrosion, or loose pins
Measure resistance and voltage at the right shock actuator connector per manufacturer specs
Check for continuity to ground on the signal wire to confirm short
If wiring and connector are good, test the actuator by swapping with the left side (if applicable) or using a known-good actuator
If actuator tests OK, suspect the suspension ECU and perform further diagnostics per service manual
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, but the suspension will default to a firm setting, reducing ride comfort and handling. Have it diagnosed soon to prevent further issues.
How much does it cost to fix?▼
Typically $150-$400 for diagnosis and repair, depending on whether the issue is wiring ($50-$150), a shock actuator ($200-$600), or the ECU ($500-$1000).
