Nissan Altima C0095: Right Rear ABS Solenoid 2 Circuit diagnosis
Code verification standard
C0095 is published with SAE J2012 / ISO 15031-6 code structure plus Nissan Altima diagnostic context.
This page covers meaning, symptoms, first checks, live data, misdiagnosis risk, and repair verification.
What does this mean?
Code C0095 indicates an electrical fault within the circuit of the second solenoid controlling the right rear wheel's anti-lock braking system. This solenoid is crucial for modulating hydraulic pressure to the right rear brake caliper during ABS activation, preventing wheel lock-up. A fault in this circuit means the ABS module cannot properly control the right rear brake, potentially leading to reduced braking efficiency, loss of ABS function for that wheel, or even the entire system, and illumination of the ABS warning light. This is typically an electrical issue (open, short, high resistance) rather than a mechanical failure of the solenoid itself, though an internal solenoid fault cannot be ruled out.
How serious is this code?
A C0095 code indicates a fault in a critical component of the Anti-lock Braking System. While the base braking system (without ABS) may still function, the ABS will be disabled, at least for the right rear wheel, and potentially for the entire system. This means that during hard braking, the right rear wheel (or any wheel if the system is fully disabled) could lock up, leading to a loss of steering control and increased stopping distances, especially on slippery surfaces. It is advisable to have this issue diagnosed and repaired promptly.
Diagnostic system: Chassis, ABS, steering, and brake control
On a Nissan Altima, the C0095 code should be diagnosed as part of the chassis, abs, steering, and brake control group. Related codes and live data from this same system can change the repair priority, so avoid replacing parts from the code name alone.
Most Common Causes for Nissan Altima
- Damaged, chafed, or broken wiring harness
- Corroded or loose electrical connector
- Faulty vehicle speed sensor (VSS)
- Faulty brake light switch
- Faulty power steering pressure sensor
Symptoms to Watch For
- ABS / traction control warning light is on
- Erratic speedometer reading
- Cruise control not functioning
- Unusual vibration during driving
- Vehicle enters reduced power / limp mode
- Check Engine Light is illuminated
Before replacing parts, check these first
- Scan ABS/chassis modules, not only generic engine codes.
- Inspect wheel speed sensor wiring, brake switch input, steering angle data, fuses, and grounds.
- Verify sensor signals while the vehicle is safely lifted or driven under controlled conditions.
- Check for blown fuses, weak battery voltage, and damaged connectors before buying major parts.
Live data to compare
- Freeze-frame conditions
- Related codes
- Circuit voltage and continuity
How to Diagnose
Common Mistakes
Replacing an ABS module before checking wheel speed sensors, damaged harnesses, brake switch data, power, and grounds. Always confirm the fault with freeze-frame data, live data, visual inspection, and circuit checks before spending money on parts.
Repair verification
After the repair, clear C0095, complete a drive cycle, and confirm the monitor runs without the code returning. Save the before/after scan report if the vehicle needs emissions inspection.
Frequently Asked Questions
Can I drive with the C0095 code?
If the check engine light is solid, you can usually drive to a safe location or mechanic. If the light is flashing, pull over immediately to prevent catastrophic engine or catalytic converter damage.
Will the C0095 code clear itself?
Once the underlying problem is fixed, the engine computer will run its self-checks. If it passes over several drive cycles, the light will turn off automatically. You can also clear it immediately using an OBD2 scanner.
Will this code fail an emissions test?
Yes. If the Check Engine Light is on due to the C0095 code, your Nissan will automatically fail an OBD2 plug-in emissions or smog test.
What should I check first for C0095?
Scan ABS/chassis modules, not only generic engine codes. Inspect wheel speed sensor wiring, brake switch input, steering angle data, fuses, and grounds. Verify sensor signals while the vehicle is safely lifted or driven under controlled conditions.

Repair Estimate
Fuse, connector, wiring, cleaning, or basic inspection
Major component replacement after live data and circuit tests confirm failure
Wheel speed sensor and wiring repairs are often moderate; ABS hydraulic module or steering module replacement should be verified first.
DIY Difficulty
Can usually be performed at home with basic hand tools.
