P0562 — System Voltage Low (Chery Context)
Written and edited by Ethan Cole, Editor-in-Chief · ✓ Technically reviewed by Daniel Wei Chen — Senior Chinese Automotive Diagnostics & Repair Specialist, Sydney · 24 October 2026.
Standard meaning: system voltage below threshold long enough to log. On Cherys this splits cleanly by drivetrain: conventional charging on the petrols, computer-managed 12V top-up on the Super Hybrids — two different failure stories behind one code.
What it means on your Chery
| If you drive… | Context | First move |
|---|---|---|
| Petrol (Tiggo 4/7/8, Omoda 5) | Battery age, terminals, alternator — the classic chain, on cars young enough that a weak battery is usually a warranty conversation. | 12V health test; terminals; then charging-system check. |
| Super Hybrid (plug-in) | The 12V boots the control systems; the traction battery tops it up on software’s schedule. Long parked spells on EV-only school runs stress the logic. | Battery test and software currency in the same dealer visit. |
Safe owner checks
- When does it happen — after sitting days (drain/top-up logic) or mid-drive (charging system)?
- Terminal condition; battery date label.
- Random multi-system warnings appearing together? Classic weak-12V theatre — one cause, many symptoms.
When it’s a workshop job
A healthy battery test plus recurring episodes = software/charging-logic territory, and on a warranted car that’s a documented dealer case, not a bigger battery from the parts shop. U-codes appearing alongside are usually this code’s echo — fix the voltage first.
Correction note: This page used to point to “the family-wide 12V pattern documented across our Chinese-brand coverage”. The owner reports behind that pattern have not been verified, so the page no longer points to it. See our corrections log.
