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

Embedded Systems Insight

What the ECU/ECM is actually computing

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.
