The C1196 OBD2 fault code relates to the ABS Outlet Valve Coil LF circuit. This is part of the vehicle's chassis control system. When the short to battery, the control module cannot properly monitor or regulate this system, which may affect braking, traction, stability, or suspension performance.
At AIscanAuto, we help drivers quickly identify OBD2 trouble codes, understand their root causes, and find the right fix — with AI-powered diagnostics that go beyond basic code reading.
Symptoms
- ABS warning light on
- Brake pedal pulsation at normal braking
- ABS activating incorrectly
- Possible brake fluid leak
- Traction control disabled
Common Causes
- Faulty component — internal damage or wear affecting the ABS Outlet Valve Coil LF
- Wiring issues — broken, corroded, or chafed wires in the circuit
- Connector problems — loose, oxidized, or moisture-damaged pins
- a short to battery voltage is detected — connects the signal line directly to 12V, causing constant high voltage
- Control module fault — rare, but the chassis control module may have an internal fault
Step-by-Step Diagnosis
- Scan with OBD2 tool — Confirm C1196 is active. Check for additional chassis DTCs.
- Visual inspection — Examine the ABS Outlet Valve Coil LF wiring and connector for corrosion or damage.
- Check voltage and ground — Use a multimeter to verify proper reference voltage.
- Test component — Compare readings to factory specs. A stuck or erratic signal confirms failure.
- Check for shorts/opens — Perform continuity tests on the wiring between the component and control module.
Repair & Solutions
- If the component is defective, replace the ABS Outlet Valve Coil LF with an OEM or quality aftermarket part.
- Repair any damaged wiring or connectors using proper methods.
- Clear the DTC with an OBD2 scanner and test drive to verify the code does not return.
- If the code persists after component replacement, inspect the control module connector or consider module testing.
