Cause
Water ingress into the footwell
A wet carpet, from a blocked bulkhead drain, a perished screen seal or a leaking heater matrix. Modules and connectors live under the seats and behind the kick panels, so the electrical symptoms appear a long way from anything the owner would connect with a damp floor.
Only the owner can report the damp, which makes it a question worth asking before any meter comes out.
Typically a moderate job.
Some of these codes mean you should stop driving
12 of the 12 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.

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.
