The C1116 error code in a Nissan typically refers to a problem with the stop lamp switch. The stop lamp switch is an electronic component that is responsible for turning on the brake lights when you press the brake pedal. The switch sends a signal to the vehicle's electronic control module (ECM) when the brake pedal is depressed, which then activates the brake lights.
When the ECM detects an issue with the stop lamp switch or its circuit, it may set the C1116 code and turn on the Check Engine Light. In some cases, this may also result in the brake lights not working correctly.
The most common cause of a C1116 code is a faulty stop lamp switch. However, it is also possible that there is an issue with the wiring or connections related to the switch. A qualified mechanic will need to perform a diagnostic test to determine the exact cause of the problem.
If the problem is a faulty stop lamp switch, the switch will need to be replaced. This is typically a simple and straightforward repair. If the issue is with the wiring or connections, the mechanic may need to repair or replace the affected components.
It is important to address the C1116 code as soon as possible, as a malfunctioning stop lamp switch can affect the vehicle's safety by causing the brake lights to not work correctly.
