Serious — Stop or limit driving

OBD Code C1244: ABS Outlet Valve Coil LR Circuit Short To Battery

Q: What does OBD code C1244 mean?

ABS Outlet Valve Coil LR Circuit Short To Battery. The ABS system's left rear outlet valve coil has an electrical short that's sending too much voltage to the battery instead of properly controlling the valve. Think of it like a water valve with a broken electrical switch that's stuck in the open position.

Q: What are the symptoms of fault code C1244?

ABS warning light illuminated on dashboard, Reduced or absent ABS function during braking, Potential loss of anti-lock braking on left rear wheel

How Your ECU Detects This

Technical sensor logic and voltage thresholds

The ECU monitors the coil circuit voltage and resistance of the LR outlet valve solenoid. When the coil shorts to battery voltage, the ECU detects abnormally high voltage (near battery voltage) instead of the normal controlled signal, triggering a fault.

Voltage & Parameter Thresholds

Parameter	Normal Range	Fault Condition
Coil Circuit Voltage	0-5V controlled PWM signal	Sustained battery voltage (12-14V)
Coil Resistance	4-12 ohms	Near 0 ohms or shorted to ground

Diagnostic & DIY Fix Guide

Check these in order — from cheapest to most complex

1

Wiring harness connector

Inspect and reseat the ABS valve solenoid connector at the modulator for corrosion or loose pins.

2

Wiring harness

Check the LR outlet valve coil wiring for damaged insulation, pinched wires, or contact with metal chassis causing a short.

3

ABS outlet valve solenoid

Replace the faulty LR outlet valve coil assembly if wiring checks pass and short persists.

⚠️

When to See a Professional Mechanic

Not all fault codes are safe to DIY

Code C1244 is classified as a serious fault. If your check engine light is flashing — not just steady — pull over safely and do not continue driving. A flashing CEL indicates an active misfire or critical failure that can cause catalytic converter damage within minutes or permanent engine harm within miles. Contact a certified mechanic immediately. Do not attempt roadside repairs on high-severity codes unless you are trained to do so.

Safety note: OBD-II codes identify the system or circuit where a fault was detected — they do not always identify the exact failed component. A professional mechanic using live sensor data will diagnose the root cause more accurately than replacing parts based on the code alone.

How to Clear Code C1244

What happens after you fix the fault

Once the fault is repaired, C1244 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.

The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.

✅ Safe to Clear When

Fault has been diagnosed and repaired
You want to confirm the repair worked
Code appeared after a sensor was cleaned

⚠️ Do Not Clear When

Preparing for an emissions/PUC test
Root cause is still undiagnosed
Check engine light is flashing

Emissions test note: Clearing codes resets OBD readiness monitors. Most vehicles need 50–100 km of mixed driving before monitors complete. Do not clear codes immediately before an emissions or PUC inspection.
