What Does C0095 Mean?
This code indicates the ABS control module has detected an electrical fault in the right rear wheel's second solenoid valve circuit. The ABS solenoid valves control hydraulic pressure during anti-lock braking events by rapidly opening and closing to modulate brake pressure. The control module detected an open circuit, short circuit, or resistance value outside acceptable parameters in the control circuit for this specific solenoid.
Safety Warning
Vehicle is unsafe to drive in emergency braking situations as the right rear wheel may lock up prematurely or ABS function may be completely disabled. Stopping distances may increase significantly and vehicle stability during hard braking is compromised. Immediate repair is strongly recommended.
Common Causes
35%
Failed ABS solenoid valve within the hydraulic control unit (HCU) due to internal coil failure, corrosion, or mechanical wear
30%
Damaged wiring harness or corroded connector between ABS control module and hydraulic unit, often from road debris, moisture intrusion, or chafing
20%
Corroded or loose electrical connector at the hydraulic control unit causing intermittent or high resistance connection
10%
Failed ABS control module with internal driver circuit failure for the solenoid channel
5%
Short to ground or power in solenoid circuit wiring due to pinched or abraded wire insulation
Diagnostic Steps
1
Step 1: Perform visual inspection of ABS hydraulic control unit, wiring harness, and connectors for visible damage, corrosion, moisture intrusion, or pinched wires. Inspect connector terminals for bent pins, corrosion, or push-back.
2
Step 2: Disconnect the ABS hydraulic control unit connector and measure resistance of the right rear solenoid #2 circuit from the HCU side (typically 2-8 ohms depending on manufacturer). Compare to specifications in service manual.
3
Step 3: Using a digital multimeter, perform continuity test on the wiring harness between ABS control module connector and HCU connector for the solenoid #2 circuit. Check for opens, shorts to ground, and shorts to power.
4
Step 4: If wiring and resistance checks are within specification, perform a voltage drop test on the solenoid circuit while commanding the solenoid active using bidirectional controls (if available) to identify high resistance connections.
5
Step 5: If all circuits test correctly, suspect internal HCU solenoid valve failure or ABS control module driver circuit failure. Swap or replace HCU first as it is more common than module failure.
6
Step 6: After repair, clear codes, perform ABS system initialization procedure per manufacturer specifications, and road test vehicle with multiple hard braking events to verify ABS function and confirm repair.

The most common cause of C0095 (Right Rear ABS Solenoid #2 Circuit Malfunction) is: Failed ABS solenoid valve within the hydraulic control unit (HCU) due to internal coil failure, corrosion, or mechanical wear
Typical repair costs for C0095 range from $200 to $1,800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
