Cause
Damaged wiring harness
Physical damage to a loom rather than to any single wire: crushing, chafing, rodent damage, or a previous repair pulling apart. The characteristic sign is several unrelated faults appearing at once, because a loom carries circuits belonging to systems that have nothing to do with each other.
A spread of codes with no common component is far more often one damaged bundle than several coincidental failures.
Typically specialist work. Needs equipment or training most home workshops do not have.
Some of these codes mean you should stop driving
43 of the 1,258 codes this can cause indicate a fault where continuing to drive risks damage or is unsafe. Which one you have matters more than the cause does — read the code's own page before deciding.

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.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.
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.
