Code P260C GMC Description
The P260C diagnostic trouble code for GMC vehicles indicates that there is a high voltage condition detected in the power take-off (PTO) relay control circuit. The PTO relay is responsible for controlling the engagement and disengagement of the power take-off system, which transfers power from the engine to auxiliary components such as hydraulic pumps, generators, or winches. When the voltage in the relay control circuit is higher than the specified range, it can lead to various issues with the operation of the power take-off system.
Common Causes of P260C GMC
- Faulty PTO relay
- Damaged wiring or connectors in the relay control circuit
- Short circuit in the control circuit
- Issues with the powertrain control module (PCM)
- Electrical issues such as a weak battery or alternator
Symptoms of P260C GMC
- Erratic engagement or disengagement of the power take-off system
- Loss of functionality in auxiliary components powered by the PTO system
- Illumination of the check engine light
- Vehicle may go into limp mode to prevent further damage
How to Fix P260C GMC
- Use a scan tool to diagnose the specific cause of the high voltage condition in the PTO relay control circuit
- Inspect and test the PTO relay and replace if necessary
- Check the wiring and connectors in the control circuit for any damage or corrosion, repairing or replacing as needed
- Clear the diagnostic trouble codes and test the power take-off system to ensure proper operation
- If the issue persists, further diagnostics may be required to identify any underlying electrical issues or PCM problems
Cost to Fix P260C GMC
The cost of repairing a P260C code for a GMC vehicle can vary depending on the specific cause of the issue.

Start by inspecting the PTO relay, wiring, and connectors for damage or corrosion. Then, use a multimeter to check for high voltage in the circuit and verify PCM functionality.
5. Can a faulty PTO relay cause the P260C code?
Yes, a malfunctioning PTO relay can cause the circuit to produce high voltage, triggering the P260C code.
6. Is it safe to drive with a P260C code on a GMC?
It’s generally safe to drive, but auxiliary systems relying on the PTO may not function correctly, which could be critical for work-related tasks.
7. How do I fix the P260C code on my GMC?
Repair or replace damaged wiring, connectors, or the PTO relay, and update or reprogram the PCM if necessary.
8. How much does it cost to fix the P260C code?
Repair costs can range from $50 to $300 depending on whether you need to replace the PTO relay, repair wiring, or address PCM issues.
9. Can a low battery cause the P260C code?
While uncommon, electrical issues like a weak battery or poor ground connections could potentially affect the PTO circuit and cause this code.
10. Do I need to clear the P260C code after repairs?
Yes, after completing repairs, use an OBDII scanner to clear the code and verify that it does not return during a test drive.
