What does the C1116 code mean?
The C1116 code is a manufacturer-specific ABS code that indicates a problem with the ABS pump motor. When this code appears, it means that the ABS pump motor is not functioning properly. This can cause a number of issues with a vehicle’s braking system, including reduced braking power, longer stopping distances, and increased risk of accidents.
So, not only will you not be able to properly unlock the brakes in case of sliding on a slippery road, but your general braking performance may be reduced which means it poses a safety risk.
What causes the C1116 code?
Even though it seems as if the code mostly malfunctions due to a bad ABS motor or module, there are quite a few potential reasons behind this code. To be sure that you are using the right solution for your situation, it’s essential to be familiar with all of these, so here’s our list of the possible causes:
Malfunctioning ABS pump motor relay
The ABS pump motor relay is responsible for supplying power to the ABS pump motor. If this relay is malfunctioning, it can cause the ABS pump motor to stop working properly. This can trigger the C1116 code. To diagnose this issue, a mechanic will need to test the relay and replace it if necessary.
Faulty ABS pump motor
The ABS pump motor itself can also be the source of the C1116 code. If the motor is faulty or damaged, it may not be able to function properly. This can cause the ABS to malfunction and trigger the C1116 code.
Damaged ABS pump motor wiring harness
The wiring harness that connects the ABS pump motor to the rest of the ABS system can become damaged over time. This can cause the motor to stop working properly and trigger this code.
Malfunctioning ABS pump motor control module
The ABS pump motor control module is responsible for regulating the speed and power of the ABS pump motor. If this module is malfunctioning, it can cause the motor to stop working properly and trigger the code.
Which car models does the C1116 code affect the most?
The C1116 code can affect a wide range of car models, but it’s most commonly found in Nissan and Infiniti vehicles. This is because these vehicles use a specific type of ABS pump motor that is more prone to malfunctioning, so here’s a list:
- Nissan Maxima: This model is affected by the code due to a faulty ABS pump motor and problems with the control module signal.
- Nissan Altima: This vehicle is affected by the code for the same reasons as the Maxima as they share some of the key components of the ABS system.
- Infiniti G35: The Inifiniti G35 is also commonly reported to deal with the C1116 problem code due to a faulty ABS pump motor.
How to diagnose the C1116 code
Since there are so many ABS-related components to check, there are all sorts of diagnostic methods you can use to pinpoint the issue behind this code in your car. So, we had no other option but to bring you a full list of possible methods to use:
Use an OBD2 scanner tool
One of the first steps in diagnosing the code is to use a diagnostic scanner to read the code and any associated codes. This can provide important information about what is causing the code and can help a mechanic identify the root cause of the issue.
Check the ABS system components
A visual inspection of the ABS system and its components can also be helpful in identifying the root cause of the code. This can involve inspecting the ABS pump motor, the wiring harness, the control module, and the electrical connectors for any signs of damage or wear.
Test the ABS pump motor relay
To test the ABS pump motor relay, you will need to use a multimeter to test the relay’s continuity. If the relay is not functioning properly, it will need to be replaced.
Check the pump motor
You can use a multimeter to test the ABS pump motor’s resistance to see if a faulty motor is the cause behind the code and replace the motor in case this turns out to be the case.
Inspecting the ABS pump motor wiring harness
You can also visually inspect the ABS pump motor wiring harness for any signs of damage and repair the issue in case you notice any wiring or connection issues.
Test the ABS control module
To test the ABS pump motor control module, you will need to use a diagnostic scanner to test the module’s functionality. If the module is not functioning properly, it will need to be replaced.
How to fix the C1116 code
Fixing the C1116 code can be challenging, but there are several potential fixes depending on the root cause of the issue. These include:
Repairing the wiring and connections
The first step in fixing the code is to visually inspect the wiring and connections around the ABS pump motor. Broken or corroded connections can cause electrical issues that trigger this code.
Replacing the ABS control module
If the wiring and connections look fine, the next step is to replace the ABS pump motor. This is a relatively common fix for this issue.
Replace other ABS-related components
Sometimes, other related components such as relays or fuses can cause issues with the ABS pump motor circuit. In these cases, replacing these components may be necessary to fix the problem.
How to prevent the C1116 code
Preventing the C1116 code from appearing can be challenging, but there are several preventative measures that can be taken. These include:
- Regularly inspecting the ABS system and its components for signs of damage or wear
- Performing routine maintenance on the affected system, such as flushing the brake fluid and replacing the brake pads
- Using high-quality parts and fluids when repairing or replacing components in the ABS system
By taking these preventative measures, car owners can help reduce the risk of the code appearing and can ensure that their vehicle’s ABS system is functioning properly.
Our take
In the end, it turns out that the code C1116 can be pretty worrying for drivers as it affects the driving safety in your vehicle. So, the best way to tackle this issue is by following the steps to diagnose and fix the code, and our guide will hopefully lead the way and help you accomplish this.
What are the symptoms of code C1116?
Symptoms of a fault in the ABS pump motor circuit can include an illuminated ABS warning light on the dashboard, a malfunctioning traction control system, and poor braking performance.
Can I still drive my car with code C1116?
It’s generally not recommended to drive your car with code C1116, as this issue can affect your vehicle’s ability to brake properly and may compromise safety. If you suspect that your vehicle has this code, it’s recommended to have it diagnosed and repaired by a qualified mechanic as soon as possible.
How is code C1116 fixed?
Fixing code C1116 generally involves inspecting the wiring and connections around the ABS pump motor, replacing the ABS pump motor if necessary, and resetting the trouble code using an appropriate scanner.
