Chevrolet Code P2535 is a common trouble code that is generated when the powertrain control module detects a high voltage on the ignition switch circuit. This code is related to a myriad of issues, all of which require careful diagnosis and repair in order to get the vehicle running properly again. The most common causes of the Chevrolet Code P2535 are the hybrid powertrain control module 2 being awake, the fuel pump control module detecting an ignition voltage that is less than 6 V, and the TCM detecting less than 2 V on the ignition voltage circuit at the TCM for longer than 10 seconds. It is important to understand the underlying causes and potential solutions for this code in order to properly diagnose and repair the issue.
Causes and Solutions for Chevrolet Code P2535
| Cause | Solution |
|---|---|
| P2534, P2535 | Check the wiring harness and replace if needed. |
| The hybrid powertrain control module 2 is awake. | Replace the hybrid powertrain control module. |
| The fuel pump control module detects that the ignition voltage is less than 6 V. | Check the voltage regulator and replace if needed. |
| The TCM detects less than 2 V on the ignition voltage circuit at the TCM for greater than 10 seconds. | Check the wiring harness and replace if needed. |
Hybrid Powertrain Control Module 2
When the hybrid powertrain control module 2 is awake, it can cause the Chevrolet Code P2535 to be generated. This can be due to an issue with the wiring harness or the module itself. In order to determine the cause, a technician will need to do a visual inspection of the wiring harness to make sure it is not damaged or corroded. If the wiring harness is in good condition, then the module itself will need to be replaced.
Fuel Pump Control Module
If the fuel pump control module detects that the ignition voltage is less than 6 V, then it can cause the Chevrolet Code P2535 to be generated. In this case, the technician will need to check the voltage regulator to make sure it is working properly and is not malfunctioning. If the voltage regulator is faulty, it will need to be replaced in order to fix the issue.
Transmission Control Module
The transmission control module can generate the Chevrolet Code P2535 if it detects less than 2 V on the ignition voltage circuit at the TCM for longer than 10 seconds. In this case, the technician will need to check the wiring harness to make sure it is not damaged or corroded. If the wiring harness is in good condition, then the technician will need to replace it in order to fix the issue.
Conclusion
The Chevrolet Code P2535 is a common trouble code that requires careful diagnosis and repair in order to get the vehicle running properly again. The most common causes of this code are the hybrid powertrain control module 2 being awake, the fuel pump control module detecting an ignition voltage that is less than 6 V, and the TCM detecting less than 2 V on the ignition voltage circuit at the TCM for longer than 10 seconds. By understanding the underlying causes and potential solutions for Chevrolet Code P2535, technicians can properly diagnose and repair the issue.
