Leading evidence: 'inactivation and removal of the pasm module' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'inactivation and removal of the pasm module' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Run (i traversed every menu item' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I have a Durametric and captured the following fault codes while the engine was running (I traversed every menu item on the left of app window):

Using Durametric, went to Front/Activations and found 3 "Radiator fans" (not sure why there's 3).

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 2005 C2S 997.1 has been sitting for a few months. It has been on a CTEK battery maintainer. I took it out for a one hour drive today. Just after engine startup, at the end of the drive, and another engine startup after a two hour rest in the garage (water temp gage showing about 120degF), it exhibited symptoms I'd not seen before.
Immediately at startup with a cold engine, the engine compartment fan came on and stayed on.
About 30 seconds after engine startup, both cold engine and warm engine, both radiator fans came on and stayed on.
I have a Durametric and captured the following fault codes while the engine was running (I traversed every menu item on the left of app window):

FWIW, I was not in ECO mode so the air conditioner compressor was probably running. I was trying to recirculate the freon and oil. (I usually run in ECO mode.)
FWIW, there's no CEL indicator showing on the instrument display.
Engine water temp about 105degF.
Started engine.
Engine compartment fan is on.
Within 30 seconds both radiator fans roaring (seemingly like they are on high).
Using Durametric, went to Front/Activations and found 3 "Radiator fans" (not sure why there's 3). See pic below.
First entry - clicked STOP. Nothing happened.
Second entry - clicked STOP. Nothing happened.
Third entry - clicked STOP. Nothing happened.
First entry - clicked START. One of the front fans (or maybe both, it got quiet) slowly spun down and then 10 seconds later it went back to high.
Second entry - clicked START. One of the front fans (or maybe both, it got quiet) slowly spun down and then 10 seconds later it went back to high.
Third entry - clicked START. Nothing happened.
Toggling the ECO button on the climate control didn't seem to make any difference.
Gas has Stabil in it.
Battery's installation date is July 2014.
Yesterday, after the battery-maintained multi-month inactivity, the car acted OK - normal starter rotation speed and fire-up time.
Today, battery's voltage after sitting all night, NOT on the battery maintainer, is 12.67v.
Why might these fans be acting abnormally?
