Maybe it's the outside temperature. It was warmer today after a week in the 20s.

2.5 NA 2008 Forester 4EAT 155k.

The AT Temp would start flashing and stay flashing until the car was restarted. Then a few days later the AWD light started flashing.

No weird shifting, no torque bind, downshifting, upshifting, everything normal. Fluids clean and normal. Air filter clean.

Charged the battery, just in case, no difference. The AT light would start flashing 1 block down the road, followed by the AWD light.

Checked any grounds I could find. Unplugged and reseated TCM connectors. Disconnected the battery for 1 hour, and reconnected it.

Lights gone and stayed off after 50 miles. Stupid lights.

Should be able to pull the codes  w/out a scanner:  https://www.subaruoutback.org/threads/05-06-09-how-to-read-diagnostic-trouble-codes-dtcs.19053/

Can't find the one on here, but that one should work for your Forester too.

 

50 miles in one trip may not trigger the code. Sometimes it's 'drive cycles' so 2-3 trips to the store may be required to 'trip' the code. 

 

Yep, the lights came back on. The procedures does not work. 2008 Forester is not CANbus. Started in 09.

I'm betting on broke wire. Will check tomorrow.

 

 

Or try this: https://www.subaruforester.org/threads/at-temp-light-flashing-how-to-read-code.237225/#post-2463841

States 'thru '04' but the Foz has the same Phase 2 4EAT thru '08?

Found the broken wire. it. Another thread elsewhere (https://www.subaruforester.org/threads/2005-automatic-trans-issue-at-temp-flashing-awd-light-starts-flashing-solved.815228/) helped.

Exact same thing here, as found and stripped back.

Like I said, it's stupid.

That's the power of  Knowledge Base Troubleshooting system.

atp.com SpotLight for aircraft.

What is this "Knowledge Base Troubleshooting system" you mention? The Internet?

Currently for aircraft.  The USMB is great!
