Just gonna post this up here, so maybe i can find it again later.
This is a software problem, a firmware update could fix, but they will not roll it out.
This throws O2 sensor codes, and then cyl codes as vehicle starts to misfire.
Simple fix is to disconnect both O2 sensors in front of cat, then clear the ECS. This will cause vehicle to kick down to "basic" settings. Then reset the ECS, and drive at 55 for 10 min, then idle at side of the road, in gear, with foot on the brake for 2 minutes.
Reset Procedure
Disconnect battery neg terminal. ( or can pull the EFI #1 and ETCS fuses).
While disconnected, turn key to the ON, not start position for 2-3 min to drain the capacitor in ECU, and reset to the baseline run conditions. This will remove the CEL , or MIL, so you can set the monitor cycles by driving, and stopping to idle w foot on the brake.

The cat temp sensor , and i think, a high altitude sensor, will eventually start causing problems again. When it starts "ticking" a lot, reset it again, and should be good until the next major storm blows thru, screwing up the high alt sensing.

ABS light reset:
First fill the brake fluid res, then clean the ANS sensor, that is magnetic, and picks up metal shards.
Now reset the ABS light, jump the TE1, to the E1 connector at the OBD connector, KEY at ON, and start tapping the brakes, about twice a minute, at least 8 times, or 4-5 minutes.
