Hyundai Ioniq 5
The battery electric on E-GMP, and the platform's defining feature changes the diagnosis: it is an 800-volt architecture, roughly double the system voltage of most electric cars here, which means the isolation, contactor and insulation-monitoring codes concern a system where the safety margins and the test equipment both differ. It also charges at 400 volts by using the drive motor and inverter as a boost converter, so a charging fault can be a motor or inverter fault rather than a charger one.

An 800-volt E-GMP car that boosts 400-volt charging through the drive motor — so charging and drive faults can share hardware.

Service information
Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
