1. What is P0562?

P0562 indicates system voltage low. The ECM monitors battery and charging voltage; when voltage drops below threshold (typically under 10.0V), this code is triggered.

Low voltage affects ignition, fuel injection, and transmission performance. Addressing it early prevents stalling and battery/alternator damage.

2. Common Causes

• Weak or failing battery (Ford Focus 2.0L case)
• Alternator malfunction (Chevrolet Cruze example)
• Loose or corroded battery terminals
• Damaged wiring harness or ground connection
• High electrical load without sufficient charging

3. Key Symptoms

• Check Engine Light with P0562 stored
• Dim headlights, weak interior lights
• Hard starting or no-start condition
• Stalling while driving
• Transmission shifting issues

4. Models Affected

• Ford: Focus 2015–2022, Escape 2017–2022
• Chevrolet: Cruze 2016–2023, Malibu 2018–2023
• Volkswagen: Jetta 2017–2023, Passat 2018–2022

5. Diagnostic Steps with UR800

• Scan with UR800 → confirm P0562 & related codes
• Check live voltage (engine on: 13.5–14.8V normal)
• Inspect battery, alternator, and wiring connections
• Test alternator output under load
• Verify grounding integrity

6. Fixes & Execution

• Replace weak battery with OEM spec
• Repair/replace faulty alternator
• Clean and tighten battery terminals
• Repair damaged ground or wiring
• Re-test with UR800 to confirm fix

7. Repair Costs

• Battery replacement: $120–$220
• Alternator replacement: $350–$650
• Wiring/ground repair: $50–$150
• Labor: $80–$150

8. Preventive Maintenance

• Check battery health every 12 months
• Inspect charging system at oil service
• Clean terminals and grounds regularly
• Use UR800 to monitor live voltage

9. Frequently Asked Questions

Can I drive with P0562? Driving short distances may be possible, but risk of stalling is high. Fix immediately.

Does UR800 help? Yes, UR800 shows real-time voltage and charging data, making P0562 diagnosis faster.

10. Summary

P0562 means system voltage is too low. Causes include weak battery, alternator failure, or wiring issues. Fixing it promptly avoids stalling and ECU issues. The ICARZONE UR800 scanner helps confirm live voltage data, diagnose accurately, and clear the code.
