C0565 ABS Control Module System Voltage High

C0565 is set when the ABS module measures a supply voltage above its permitted maximum; excess voltage can damage the valve and pump drivers, so the module stops regulating. Mitsubishi maps its C1056-17 to C0565 on the 2023 Outlander PHEV: 16 V or more on the ignition feed within 1 s, ASC, ABS, brake and parking brake lamps plus the MIL after two trips; ABS, EBD, ASC, brake assist and the electric parking brake are suspended. Ford's hybrids flag voltage above 16.9 V. Causes lie in the charging side – a faulty regulator or DC/DC converter, or jump-starting or charging with too high a voltage. The low-voltage counterpart is C0564.

Likely causes

Faulty alternator regulator or DC/DC converter overcharging the 12 V system
Jump-start or battery charger set to an excessive voltage
Poor ground making the module read voltage too high

Symptoms

  • ABS, stability, brake and parking brake warnings
  • Check-engine lamp on some models
  • Bulbs burning out or other modules reporting overvoltage
