What C0565 means
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.
C0565 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.3 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of C0565
- ABS, stability, brake and parking brake warnings
- Check-engine lamp on some models
- Bulbs burning out or other modules reporting overvoltage
Common causes of C0565
- Most likelyFaulty alternator regulator or DC/DC converter overcharging the 12 V system
- PossibleJump-start or battery charger set to an excessive voltage
- Less likelyPoor ground making the module read voltage too high
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0565 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0565
What does C0565 mean?
C0565 means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with C0565?
Drive gently and only to a workshop. With C0565 the car can go into limp mode (reduced power) to protect itself.
Will C0565 fail an emissions test?
C0565 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0565 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. This is a job for a workshop.
Will C0565 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
