Cause
Damaged module supply wiring
The module's own feed rather than anything it controls. A module short of voltage misbehaves rather than dying, so it records faults naming healthy parts — fix the supply, clear the codes, drive, then read again.
Typically a moderate job.
Codes this can cause (10)
Codes where this is a likely explanation first, rather than merely a possible one.
- P0882 Transmission Control Module Power Input Signal Low Likely for this code High
- P0884 Transmission Control Module Power Input Signal Intermittent Likely for this code High

- P2670 Actuator Supply Voltage B Circuit Low High
- P2685 Actuator Supply Voltage C Circuit Low High
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.
