C1244 — ABS Outlet Valve Coil LR Circuit Short To Battery #

The code description may vary depending on the vehicle manufacturer. Below are some known variations of the code label:

• ABS Outlet Valve Coil Left Rear Circuit Short To Battery (Ford, Toyota)
• ABS Solenoid Valve Circuit Short (Left Rear, Outlet) (Hyundai, Kia)
• Left Rear ABS Outlet Valve Circuit High (Lexus)

Summary of DTC C1244 #

DTC C1244 indicates that the Anti-lock Braking System (ABS) control module has detected an electrical short to battery voltage in the circuit that controls the left rear (LR) outlet valve coil. The outlet valve coil is an essential component within the ABS hydraulic modulator, responsible for releasing brake pressure at the left rear wheel during ABS operation to prevent wheel lockup. When the circuit is shorted to battery, it means the control module is seeing a voltage much higher than expected, suggesting a wiring or component fault. This code commonly triggers the ABS warning light and disables ABS function for the affected wheel. Addressing this issue promptly is crucial to maintaining optimal braking performance and safety.

Common Symptoms for DTC C1244 #

When DTC C1244 is present, your vehicle may display several noticeable symptoms. The ABS system may become partially or fully disabled, which can compromise safe braking under slippery or emergency conditions. The warning lights on your dashboard will likely illuminate, and you may notice a change in how the brakes feel, especially during hard stops or on wet surfaces. Sometimes, the only symptom is an illuminated ABS warning light, but it’s important not to ignore it.

• ABS warning light illuminated
• Stability or traction control warning lights on (if equipped)
• Loss of ABS function at the left rear wheel
• Increased risk of wheel lockup under hard braking
• Brake pedal may feel firmer than normal

Probable Causes for DTC C1244 (Most to Least Common) #

The causes behind a C1244 code often relate to electrical faults within the ABS circuit for the left rear outlet valve. The most common reasons stem from wiring problems, component failure, or corrosion. Here is the typical order of probability:

1. Damaged or shorted wiring harness to the left rear ABS outlet valve coil
2. Faulty ABS hydraulic control module (HCU) or solenoid valve (internal short)
3. Corroded or loose connector at the ABS module or valve coil
4. Incorrect repair, modification, or spliced wires in the ABS circuit
5. Water intrusion or contamination at connectors or wiring

Step-by-Step Diagnostic Guide for C1244 #

Diagnosing C1244 requires a methodical approach. Always begin with a visual inspection and basic diagnostics before proceeding to component-level testing. Here’s a recommended step-by-step process:

• 1. Scan for related DTCs in the ABS module and note any additional codes that may help narrow the root cause.
• 2. Perform a visual inspection of the wiring harness and connectors for damage, corrosion, or signs of shorting near the ABS module and left rear wheel.
• 3. Check battery voltage at the affected circuit to confirm if the wire is indeed shorted to power.
• 4. Disconnect the ABS module connector and check the resistance of the left rear outlet valve coil. Compare with OEM specifications.
• 5. Inspect the harness for continuity between the ABS module and the valve coil. Look for shorts to power or ground.
• 6. Test the ABS module if wiring and valve coil check out, as an internal short may be present.
• 7. Repair or replace damaged wiring, connectors, or components as needed.
• 8. Clear codes and retest to verify the repair.

Possible Repairs for C1244 #

Repairing a C1244 code involves addressing the specific cause identified during diagnostics. Most repairs are straightforward, but accuracy is key to avoid unnecessary part replacement. Always use OEM or high-quality parts for reliability.

• Repair or replace damaged wiring between the ABS module and the left rear outlet valve coil.
• Clean or replace corroded connectors at the ABS module or valve coil.
• Replace the ABS outlet valve coil (usually part of the hydraulic control unit) if it is internally shorted.
• Replace the ABS control module (HCU) if internal faults are detected and all other components test good.
• Correct any improper wiring repairs or splices in the circuit.

Is It Safe to Drive With Code C1244? #

Driving with code C1244 is not recommended for extended periods. While your conventional brakes will continue to operate, the ABS system may be partially or completely disabled for the affected wheel. This significantly increases the risk of wheel lockup and loss of control under hard braking or on slippery surfaces. For your safety and to prevent further damage, have this issue diagnosed and repaired as soon as possible.

Vehicles Most Commonly Affected by C1244 #

While C1244 can appear on any vehicle equipped with ABS, it is most commonly reported in certain makes and models that use similar ABS control modules or hydraulic units. If you own one of these vehicles, pay special attention to any ABS warning lights or symptoms.

• Ford (Escape, Explorer, F-150, Fusion)
• Toyota (Camry, RAV4, Highlander)
• Lexus (ES, RX series)
• Hyundai (Sonata, Elantra, Santa Fe)
• Kia (Optima, Sorento)

Common Mistakes & Best Practices with C1244 #

Misdiagnosis is a frequent issue with C1244, often due to skipping essential diagnostic steps or replacing expensive parts prematurely. To ensure an effective repair, always follow best practices and avoid these common pitfalls:

• Not performing a thorough visual inspection of wiring and connectors before replacing parts
• Overlooking water intrusion or corrosion at the ABS module or connector
• Failing to use OEM wiring diagrams or specifications during diagnosis
• Replacing the ABS module without first confirming the integrity of the wiring and valve coil
• Neglecting to clear codes and road-test after repairs

Quick FAQ for C1244 #

Here are some rapid answers to common questions about DTC C1244:

• Q: Will clearing the code fix the problem?
  A: No. Clearing the code without addressing the root cause will only temporarily turn off the warning light. The code will return as soon as the fault is detected again.
• Q: Can I replace just the outlet valve coil?
  A: In most OEM designs, the outlet valve coil is integrated into the ABS hydraulic control unit (HCU), so replacing the entire unit is usually required. Always check your vehicle’s service manual for specifics.
