By Ezra Lane You’re dealing with the C1108 Nissan code, an issue in your ABS pump motor circuit that affects braking efficiency and safety. This problem often arises from faulty wiring, motor issues, or ECU problems, highlighted by symptoms such as an activated ABS warning light, inconsistent braking, and increased stopping distances. To diagnose and repair this, you’ll need tools like a diagnostic scanner, multimeter, and possibly an oscilloscope to check the sensor’s outputs. Repair costs can range from $150 to $450, depending on the damage and your vehicle’s model. With a thorough check and fix, you can ensure your vehicle’s braking system functions optimally, paving the way for safer driving experiences.
C1108 Nissan Code Meaning
The C1108 code in a Nissan indicates a malfunction in the ABS pump motor circuit, affecting braking efficiency.
Causes may include faulty wiring, a malfunctioning motor, or ECU issues.
Diagnosis requires advanced scanning tools, with repair costs varying based on damage, model, and service rates.
Error Code C1108 Symptoms
When a C1108 error code shows up in your Nissan, it means there’s a problem with the ABS pump motor circuit, which can affect how your car brakes.
Here are some signs you might notice:
- ABS Light On: The ABS warning light on your dashboard turns on, indicating an issue with your braking system.
- Braking Problems: The car may not brake smoothly or consistently, which can be a problem when you need to stop quickly.
- Car Pulls to One Side: The car might pull to the left when braking, suggesting a problem with the front left sensor.
- Longer Stopping Distances: The car may take more time to stop than usual, which can be risky.
Sometimes, the traction control mightn’t work right or turn off, which can affect how stable the car feels.
If you notice these signs, it’s time to get it checked to keep driving safely.
Causes of Nissan C1108 Fault Code
The C1108 error code in a Nissan vehicle is often linked to the front left sensor 2 in the ABS pump motor circuit. This sensor helps track wheel speed. When problems occur, this error code can show up.
Common reasons for the C1108 code include:
- Broken Wires: If the wires to the front left sensor 2 are broken, the signal can get messed up. This might happen due to wear or accidents.
- Rusty Connections: Over time, moisture or dirt can cause connections to rust. Rust can block the sensor from sending data correctly.
- Faulty ECU: The ECU controls the ABS system. If it acts up, it might read signals wrong and show an error code.
- Wheel Issues: Problems with wheel bearings or the hub can stop the sensor from reading wheel speed right, leading to the C1108 code.
Regular checks and fixing these issues quickly can help prevent this error code.
Tools Needed to Diagnose
To figure out what’s wrong with the Nissan C1108 code, you’ll need some tools. These tools help you find the problem with the ABS pump motor circuit.
Here’s what you’ll need:
- Diagnostic Scanner: This tool reads and clears the C1108 and other trouble codes from your Nissan’s computer.
- Multimeter: Use this to check the voltage and resistance in the ABS pump motor circuit. It helps you see if the electrical parts are working right.
- Oscilloscope: This tool shows the waveform signals from the ABS pump motor. It helps find issues that other tools might miss.
- Basic Hand Tools: A set of wrenches and screwdrivers lets you get to the ABS pump motor and its connections. You might need them to check and fix connections.
A repair manual for your Nissan model is also helpful. It gives you wiring diagrams and details to make sure you do everything correctly.
How to Fix C1108 Nissan Error Code – Step by Step
Step 1:
Use a diagnostic scanner to confirm the C1108 error code and identify the problem with the ABS pump motor circuit. Focus on examining the front left sensor 2.
Step 2:
Inspect the sensor, wiring, and connections for any signs of damage, corrosion, or disconnection. Ensure all components are in good condition and properly connected.
Step 3:
Test the sensor’s electrical output using a multimeter or oscilloscope. Verify that the output aligns with the manufacturer’s specifications. If the sensor is faulty, replace it with a new OEM sensor to ensure system reliability.
Step 4:
Clear the diagnostic trouble codes from the ECU. This reset will remove any residual memory of resolved issues, ensuring a fresh start for the system.
Step 5:
Conduct a road test to verify that the repairs have effectively addressed the issue and that the ABS system is operating correctly.
With these steps, your Nissan’s ABS system should be restored to optimal performance.
Common Diagnosis Mistakes
When fixing the C1108 Nissan error code, be aware of common mistakes that can make repairs harder:
- Check Wiring and Connections: Make sure to examine the wiring and connections of the ABS pump motor circuit. Missing this step may lead you to think the problem is elsewhere.
- Look at the ABS Module: Don’t just focus on the pump motor. Look at the ABS module too, as skipping this can hide other problems.
- Don’t Rely Only on Codes: Diagnostic trouble codes are helpful but need further checking to find the real cause of the C1108 code.
- Consider Related Parts: Wheel speed sensors and the ECU can impact how the ABS system works. Make sure to check these parts too.
After repairs, take the car for a road test to ensure everything is working right and to avoid any further issues.
C1108 Nissan Repair Cost
Fixing the C1108 issue in a Nissan usually costs between $150 and $450. This amount includes both parts and labor. A new front left sensor can cost from $50 to $150, depending on its brand and quality.
Labor costs to diagnose and replace the sensor typically range from $100 to $300.
If there are more issues, like bad wiring or problems with the Electronic Control Unit (ECU), costs can go higher. It’s a good idea to get a detailed check to find out exactly what’s wrong, so you don’t spend extra money on things you don’t need.
Visit a trusted auto repair shop to get a precise cost estimate. Prices can change based on your car’s model and the condition of other parts.
A good mechanic will explain prices clearly and tell you why each step is needed for the repair.
