Possible Causes of C1185 Code in Nissan
The C1185 code in Nissan refers to a malfunction in the Intelligent Cruise Control (ICC) unit. This code indicates that there is a problem with the communication between the ICC unit and the Engine Control Module (ECM). Here are some of the possible causes of the C1185 code:
- Failed ICC unit: The most common cause of the C1185 code is a failed ICC unit. The ICC unit is responsible for controlling the cruise control system, and if it fails, it can cause the code to appear.
- Malfunctioning ECM: The ECM is responsible for communicating with the ICC unit, and if it malfunctions, it can cause the code to appear.
- Wiring issues: Wiring issues can also cause the C1185 code to appear. If there is a problem with the wiring between the ICC unit and the ECM, it can cause communication problems and trigger the code.
- Failed brake light switch: The brake light switch is an important component of the cruise control system. If it fails, it can cause the code to appear.
- Failed speed sensor: The speed sensor is responsible for measuring the vehicle’s speed, and if it fails, it can cause the code to appear.
- Failed throttle actuator: The throttle actuator is responsible for controlling the throttle, and if it fails, it can cause the code to appear.
It is important to note that the C1185 code can be caused by a combination of these factors. Therefore, it is important to diagnose the problem thoroughly to determine the root cause of the code. A professional mechanic can use specialized diagnostic tools to identify the cause of the code and recommend the appropriate repairs.This response was truncated by the cut-off limit (max tokens).

Fixes for C1185 Code in Nissan
The C1185 code in Nissan indicates a problem with the Intelligent Cruise Control Unit. This code is usually triggered when there is a malfunction in the system, which can cause the cruise control to stop working. Here are some of the fixes for the C1185 code in Nissan:
- Check the wiring: The first thing you should do is check the wiring of the Intelligent Cruise Control Unit. Make sure that all the connections are secure and that there are no loose wires. If you find any damaged wires, you should replace them immediately.
- Replace the Intelligent Cruise Control Unit: If the wiring is not the problem, then the issue may be with the Intelligent Cruise Control Unit itself. In this case, you will need to replace the unit with a new one. This is a more expensive fix, but it is necessary if the unit is faulty.
- Check the brake switch: Another possible cause of the C1185 code is a faulty brake switch. The brake switch is responsible for disengaging the cruise control when the brakes are applied. If the switch is not working properly, it can cause the cruise control to malfunction. Check the brake switch and replace it if necessary.
- Check the speed sensor: The speed sensor is another component that can cause the C1185 code to appear. The speed sensor is responsible for measuring the speed of the vehicle and sending that information to the cruise control system. If the sensor is not working properly, it can cause the cruise control to malfunction. Check the speed sensor and replace it if necessary.
- Check the vacuum lines: The vacuum lines are responsible for providing the necessary vacuum pressure to the cruise control system. If there is a leak in the vacuum lines, it can cause the cruise control to malfunction. Check the vacuum lines and replace them if necessary.
