P260DPTO Engaged Lamp Control Circuit
- Generic OBD-II code · Powertrain
- How the car detects it
- P260D concerns the output that drives the lamp or LED telling the operator that the power take-off is engaged; the module has found a fault in that lamp circuit. For GM's heavy-duty pickup chassis cabs, upfitter bulletin UI 80c explains how such an indicator behaves: the LED in the PTO switch blinks quickly while the relay is energized, turns steady once load feedback confirms engagement or after 3 s without feedback, and blinks slowly when a memory speed is stored. A remote PTO indicator can be wired as well. GM's PTO code table does not list P260D, and no other maker documents it publicly. The PTO itself may work normally, but the operator loses the visual confirmation, which matters for safe work with tippers, cranes or pumps. P260A to P260C cover the control circuit itself.
