What Does Code P0561 Mean? The OBD-II diagnostic trouble code P0561 indicates that the Powertrain Control Module (PCM), also commonly referred to as the Engine Control Module (ECM), has detected an unstable system voltage. This means the voltage supplied to or monitored by the PCM is fluctuating erratically or falling outside of its manufacturer-specified operating […]

What Does Code P0562 Mean? The OBD-II diagnostic trouble code P0562, “System Voltage Low,” signifies that the Powertrain Control Module (PCM), also commonly referred to as the Engine Control Module (ECM), has detected an electrical system voltage below a calibrated threshold for a specified duration. This threshold typically ranges from 11.5 to 11.8 volts, and […]

What Does Code P0563 Mean? DTC P0563 indicates that the Powertrain Control Module (PCM), often referred to as the Engine Control Module (ECM) or Engine Control Unit (ECU), has detected an abnormally high voltage reading within the vehicle’s electrical system. The PCM continuously monitors the system voltage, which typically operates within a narrow range, usually […]

What Does Code P0565 Mean? DTC P0565 signifies a “Cruise Control On Signal Malfunction.” This diagnostic trouble code is set by the Engine Control Module (ECM) or Powertrain Control Module (PCM) when it detects an illogical or absent input from the cruise control master “ON” switch circuit. The ECM/PCM continuously monitors the electrical state of […]

What Does Code P0566 Mean? DTC P0566 indicates a malfunction in the circuit responsible for signaling the Engine Control Module (ECM), or Powertrain Control Module (PCM), that the cruise control system is in an “off” or disengaged state. This code is specifically triggered when the ECM/PCM detects an anomalous voltage reading or an illogical signal […]

What Does Code P0567 Mean? DTC P0567 signifies a detected malfunction in the cruise control system’s resume signal circuit. The Powertrain Control Module (PCM), or Engine Control Module (ECM) in some architectures, is responsible for monitoring the electrical integrity and operational state of the various cruise control input switches. Specifically, for P0567, the PCM has […]

What Does Code P0568 Mean? DTC P0568 indicates a “Cruise Control Set Signal Malfunction.” This code is triggered by the Engine Control Module (ECM), or Powertrain Control Module (PCM), when it detects an implausible or incorrect electrical signal from the cruise control “SET” switch input. The ECM/PCM continuously monitors various inputs from the cruise control […]

What Does Code P0569 Mean? DTC P0569 signifies a malfunction within the cruise control system’s “coast” signal circuit. The Engine Control Module (ECM), or Powertrain Control Module (PCM), continuously monitors various input signals from the cruise control switch assembly to manage vehicle speed. The “coast” function typically allows the driver to incrementally decrease the set […]

What Does Code P0570 Mean? The OBD-II diagnostic trouble code P0570 signifies a “Cruise Control Accel Signal Malfunction.” This code is set by the Engine Control Module (ECM) or Powertrain Control Module (PCM) when it detects an implausible, intermittent, open, or shorted electrical signal from the cruise control accelerator switch. The “ACCEL” (accelerate) function is […]

What Does Code P0571 Mean? The diagnostic trouble code P0571 indicates a “Cruise Control/Brake Switch A Circuit Malfunction.” This code is set by the Powertrain Control Module (PCM) or Engine Control Module (ECM) when it detects an electrical anomaly within the primary circuit of the brake pedal position (BPP) switch, also commonly referred to as […]
