Possible Causes of C118C Code in Nissan EV/HEV System
The C118C code in Nissan EV/HEV system indicates a problem with the hybrid battery pack voltage sensor circuit. This code can be triggered by various issues, including:
1. Faulty hybrid battery pack voltage sensor: The hybrid battery pack voltage sensor is responsible for measuring the voltage of the battery pack. If this sensor is faulty, it can send incorrect signals to the engine control module (ECM), triggering the C118C code.
2. Wiring issues: The wiring that connects the hybrid battery pack voltage sensor to the ECM can become damaged or corroded over time. This can cause a poor connection or a short circuit, leading to the C118C code.
3. Failed ECM: In some cases, the ECM itself may be faulty and unable to receive or process signals from the hybrid battery pack voltage sensor. This can cause the C118C code to appear.
4. Battery pack issues: If the hybrid battery pack is damaged or has a low charge, it can cause the voltage sensor to send incorrect signals to the ECM, triggering the C118C code.
5. Software issues: Sometimes, the C118C code can be caused by a software glitch in the ECM. This can be resolved by updating the ECM software to the latest version.
6. Other electrical issues: There may be other electrical issues in the vehicle that are causing the C118C code to appear. These can include problems with the alternator, starter, or other components.
