Post Transaxle/Cooling System Warning Light (!)

I know this topic has been touched on in several different posts, so I wanted to bring it into a specific topic as it seems to be a fairly common problem and I now know the solution works in this case thanks to several who posted on these forums. So thank you! You saved me a lot of money!

1st of all the problem: I have a 2002 Focus Wagon SE with the ZTEC DOHC mototr in it. The "Multifunction Light":Transaxle/Cooling System Warning Light or better known as the yellow (!) light on the guage board comes on in the first few minutes of driving, but then goes off after a short time.

Obviously, the owner's manual simply says "have vehicle serviced". So I take it to a mechanic since I don't have a code puller for my new used car. The mechanic tells me it's the code for the transmission temperature getting too high. (He didn't give me the code #, sorry.) I think to myself, "can't be getting too hot if it comes on in the first few minutes of driving." So, after researching the forums here, I take out the battery and have it tested. Here's where it gets interesting and noteworthy!

The battery tests show that it is RIGHT ON THE VERGE of needing replacement. Under normal conditions I actually would not have replaced the battery. Under a load test it showed 12.4 volts at hook up, then only dropped to 10.4 at the lowest point on a 60 second cycled load test. The computer asked what the temperature was and if you choose 70F, it says "replace battery", if you choose 32F, it says "good battery". (Makes sense if you know anything about battery performance.)

Solution: I opt to replace the battery.

Results: No light since replacing the battery! My mechanic friend isn't quite convinced I don't think, but so far the results say otherwise.

SO! If you experience a similar situation with the light, check the battery first! I know it sounds wierd, but it makes some sense if you think about it. The computer makes decisions primarily based on voltage readings from the different sensors in the vehicle. If those voltages are out of spec, you get a warning light. In start up, the computer is relying on... the battery for voltage supply. Having been a mechanic for fours years in the military and several years after before changing careers, I have seen stranger things happen.

Just started seeing this problem.

When I first start the car, and drive to the stop sign by my house, then pull away, the car will hesitate (almost as if a power surge occurred).

The light comes on 1 time a day for 1-2 seconds then is off the rest of the time.
I have experienced this 2 times now. The first time was scary, the second, surprising.

I know it is not an overheating, cause like you said, driving it for 30 seconds does not cause an overheat.

I think it is time for replacing the battery anyhow, been about 2 years or so.
Thanks for the info.

Hey mercury! Did you change the battery? Did it help? Nov173 is right that betteries should last longer than two or three years. I didn't really get a stumble on mine either. What were your results?

Well, I guess along with my lunch I'll be eating crow. The figgin' light's back on. Not as often now, but it comes on ONLY when the vehicle is first started in the AM and the temp guage says cold and only for a minute or two. Then goes out. And never comes on when it's warm. That is REALLY irritating!

When turning the heater on, if is not heating enough it means that is time for a coolant flush. This will help circulate around the transmission cooling system.

Old thread, notice the OP's date...Yea you flush the cooling system & replace w/ new coolant or it could be a blend door/cable issue. For the trans, flush the trans fluid out & replace the filter.

Angry Light coming on

When I turn on my AC on the transaxle/cooling system light comes on the car bogs down and the temperature slams over into the red what could be causing this. It started doing it after I has the slave cylinder replaced.
