System Voltage Low
A control module detected supply voltage below its monitoring limit. A weak battery, charging fault or excessive voltage drop can cause this, so P0562 does not diagnose a failed alternator. The event matters: cranking voltage differs from normal operation. On hybrids, the low-voltage charging source may be a converter, requiring a different vehicle-specific test approach.
Can I keep driving?
A charging warning with dimming lights, stalling, burning odor, smoke or changed steering requires a safe stop and roadside help. Do not assume the battery will last. If there are no symptoms, obtain shop guidance before driving again.
Flashing light, burning smell or smoke? Pull over safely. Danger to life: call 911.
What does this code mean for your car?
The same code can need different checks depending on the model and engine. Enter your vehicle details to find relevant sources and checks.
Symptoms
- Slow cranking or difficult starting
- Dimming lights or electronic resets
- Charging warning or several warnings together
Possible causes
- 1Weak or discharged battery
- 2Charging system not supplying as required
- 3High-resistance power or ground connections
- 4Accessory belt fault where it drives the charging source
These possibilities are not ranked by frequency and do not diagnose your vehicle.
Checks you can safely do yourself
Safe checks only: engine off and cold, car on level ground.
- Save the code and freeze-frame data if your scanner offers them, without clearing anything.
- With the vehicle off and cool, look for visible battery damage or corrosion without touching terminals or approaching high-voltage cables.
When you need a shop
Request battery-condition, charging-output and supply/ground voltage-drop tests. Determine whether low voltage explains other codes. Do not disconnect a battery with the engine running or test high-voltage systems at home.
How much does it cost?
A US repair estimate needs a diagnosis and a local shop quote.
No verified US repair quote is available for this fault. The price depends on diagnosis, vehicle, parts and local labor; request 2-3 itemized quotes.

Can I keep driving with P0562?
A charging warning with dimming lights, stalling, burning odor, smoke or changed steering requires a safe stop and roadside help. Do not assume the battery will last. If there are no symptoms, obtain shop guidance before driving again.
What can cause P0562?
Possible causes include weak or discharged battery; charging system not supplying as required; high-resistance power or ground connections; accessory belt fault where it drives the charging source. These are diagnostic possibilities, not a confirmed diagnosis or a parts shopping list.
Does clearing the code fix the problem?
No. Clearing a code does not repair the problem or prove that no fault exists. It may erase useful evidence and reset readiness monitors. Save codes and freeze-frame data first; confirming a repair requires the vehicle-specific checks.
What if this code appears during a used-car inspection?
Arrange an independent professional pre-purchase inspection before committing. Request a complete scan, readiness status and diagnosis of the relevant system. Get written findings and a repair estimate; an unlit warning lamp does not replace inspection.
