This means there's a problem with the car's braking system, specifically with a small part that helps control the brakes on the front left wheel. It's like a switch that isn't working right.
The ABS (Anti-lock Braking System) uses valves to control the brake pressure to each wheel. If there's a circuit failure in the inlet valve coil for the left front wheel, it can affect braking performance.
The C1198 code indicates a malfunction in the electrical circuit of the ABS inlet valve coil for the left front (LF) wheel. This coil is responsible for opening and closing the valve, which modulates brake pressure to prevent wheel lock-up during braking. A failure in this circuit means the ABS may not function properly, potentially leading to reduced braking efficiency.
• ABS warning light on
• Reduced braking performance
• Unusual noises during braking
• Faulty ABS inlet valve coil
• Damaged wiring or connectors
• Malfunctioning ABS control module

Inlet Valve Coil: A component that controls the opening and closing of the brake fluid inlet valve.
• Inspect the wiring and connectors for damage or corrosion.
• Test the ABS inlet valve coil for proper resistance.
• Check the ABS control module for any faults.
• Replace the faulty ABS inlet valve coil.
• Repair or replace damaged wiring or connectors.
• Replace the ABS control module if necessary.

• Chevrolet Silverado
• Toyota Camry
• Regularly inspect ABS wiring and connectors.
• Perform routine ABS system checks.
• Keep the vehicle's electrical system in good condition.
ABS System Issue
• Do not ignore the ABS warning light.
• Have your brakes inspected by a professional.
• Avoid hard braking until the issue is resolved.
Check with the vehicle manufacturer for coverage details, as some ABS components may be covered under warranty.
ABS-related codes have been common in vehicles with electronic braking systems, especially as these systems age.
Moderate – While the vehicle may still be drivable, the ABS system's failure can lead to reduced braking performance.
Driving with a malfunctioning ABS can be dangerous, especially in wet or slippery conditions. It is advised to address this issue promptly.
• Vehicle stationary
• Ignition on
The ABS inlet valve coil is located near the ABS module, usually in the engine bay or near the wheel well of the left front wheel.
Q: Can I drive with the C1198 code?
A: While you can drive, it's not recommended as the ABS may not function properly, affecting braking performance.
Q: How do I reset the ABS light?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code and reset the light.
