ABS Code C1195: LF Outlet Valve Circuit Open
Diagnostic trouble code C1195 indicates that the ABS control module has detected an open circuit in the outlet valve solenoid for the left front wheel. This valve is part of the ABS hydraulic actuator and is responsible for releasing brake pressure during emergency braking to prevent wheel lock. An open circuit prevents the solenoid from being energized, so the module cannot modulate pressure in the left front brake circuit. This disables ABS intervention on that wheel or may trigger a fail-safe strategy that deactivates the entire ABS system.
1. Commonly Affected Makes
2. Most Common Causes
- Internal open circuit in the left front outlet valve solenoid within the ABS hydraulic actuator/modulator assembly
- Open, cut, or disconnected wiring between the ABS control module and the left front valve solenoid
- Corroded, oxidized, or high-resistance terminals, pins, or connectors in the solenoid circuit
- Internal failure of the ABS control module (valve driver circuit damaged)
3. Symptoms You Will Notice
- ABS warning light illuminated on the dashboard
- Possible loss of ABS function on the left front wheel or complete ABS system deactivation
4. Step-by-Step Diagnosis
Scan the ABS module for codes and verify C1195 is present
Visually inspect the wiring and connectors at the ABS module and hydraulic actuator for damage, corrosion, or loose connections
Measure resistance of the left front outlet valve solenoid between the appropriate pins at the ABS module connector; compare to specifications (typically 2-10 ohms)
If resistance is out of range, test directly at the actuator connector to isolate the fault to the actuator or wiring
Check for continuity and shorts in the wiring harness between the module and actuator
If all wiring and solenoid tests pass, suspect a faulty ABS control module
5. Frequently Asked Questions
Is it safe to drive?▼
You can still drive, but the ABS system may be partially or fully disabled. Braking performance is normal under non-panic conditions, but during hard braking the front left wheel may lock up. It is recommended to have the issue diagnosed and repaired promptly.
How much does it cost to fix?▼
Repair costs vary widely. If it's a wiring or connector issue, expect $100-$300. If the ABS actuator needs replacement, parts and labor can range from $500 to $1,200. A new ABS module may cost $800-$1,500 including programming.
