The P1651 diagnostic trouble code (DTC) indicates a fault in the PCM (Powertrain Control Module) output controls. The PCM is the brain of the vehicle's engine management system, responsible for controlling various functions such as fuel injection, ignition timing, and emissions.

2021年1月12日 · The Diagnostic Trouble Code (DTC) P1650 and P1651 will set if there is an open, short to ground or short to voltage on any of the QDM output circuits, faulty MIL circuit, faulty upshift light circuit, faulty cooling fan relay circuit or A/C relay circuit. Fault detected for 5 seconds will set P1651. Fault detected for 20 seconds will set P1650.

The P1651 fault code indicates a problem with the Quad Driver Module (QDM) in the Powertrain Control Module (PCM). The QDM is an electronic switch that controls 4 separate outputs. It completes a ground circuit when switched on, allowing it to independently control each output.

The P1651 OBDII fault code is set when an improper voltage level is found on the ODM B output that controls the fan 1 relay. Check Engine lamp illuminated. Problems arising from the starter motor. Problems with the gears. Unstable engine. Low voltage. The factors by which the P1651 OBD2 diagnostic code is stored are:
