Understanding the C1112 ABS Power Relay Coil Short Circuit to Ground Issue

Before we dive into the solution, it’s crucial to understand what the C1112 ABS Power Relay Coil Short Circuit to Ground issue is. This problem occurs when the Anti-lock Braking System (ABS) power relay coil has a short circuit to the ground. This can lead to a variety of issues, including a malfunctioning ABS, which can be dangerous if not addressed promptly.

Signs of a C1112 ABS Power Relay Coil Short Circuit to Ground Issue

There are several signs that your vehicle may be experiencing this issue. These include the ABS warning light illuminating on your dashboard, decreased brake performance, and unusual noises when braking. If you notice any of these signs, it’s time to take action.

Diagnosing the C1112 ABS Power Relay Coil Short Circuit to Ground Issue

Now that we’ve covered what this issue is and the signs to look out for, let’s move on to diagnosing the problem.

Step 1: Check the ABS Power Relay

The first step in diagnosing this issue is to check the ABS power relay. This component is responsible for supplying power to the ABS system. If it’s faulty, it could be causing the short circuit.

Step 2: Inspect the Wiring

Next, inspect the wiring connected to the ABS power relay. Look for any signs of damage, such as fraying or corrosion. Damaged wiring can cause a short circuit, leading to the C1112 code.

Step 3: Use a Multimeter

A multimeter can be a handy tool for diagnosing electrical issues. Use it to check for continuity between the ABS power relay coil and the ground. If there’s continuity, it means there’s a short circuit.
