Hi, my car got several problems, but since it showed up and disappeared back and forth I cannot diagnosed either by me nor stealership.
1. I got a P0113 code, but next time (overnight) after cold start, the code will disappear by itself. I have cleaned IAT sensor, it did not help. Then I replaced it with a new OEM IAT sensor it does not help either. According to DTC P0113 on workshop manual, I found out I need to diagnose the circuit as well, but Can anyone enlighten me where to how to do those please? I appreciate if you can offer me some links which I can learn by myself about circuit diagnose.
2. And my ABS and DSC light will sometime show up, most of the cases are that after I filled up the car, I made a turn not sharp at all at low speed or when I back up from parking lot after warming up the car the lights showed up together, but after next day's cold start and driving for several seconds, it disappeared by themselves. I do searched and find a thread for ABS and DSC light, but I still cannot fix my problem.
3. My charging system light would sometime on, after a while it would disappear. Due to the P0113 charging system light, DSC light and CEL would on together sometime. But sometime, the charging system light will be on alone. I wondering whether this related to the above 2 problems?
I never got problem with starting my 8. I got my battery checked at advance auto parts today, and here is the info, it said I need to replace my battery, does anyone know if it may lead to those problems? And also, they checked my alternator, and it shows alright. Note: when checking this, the battery light and CEL are off, but DSC and ABS light are on.
Bellow is the checking result I got today, and some real time data pulled out by Torque app. Does anyone know if I can read ABS light or DSC light by torque or other app? I have a EML 327 OBDII reader.
Here is the test by Torque, I dont know what does it mean for the failed two parts which I have highlighted, thanks for any input.

And here is the battery test and charging system test result:


Sorry I have such a lot of questions. Thanks for any input I do appreciate ur help and time.

Replace the battery and clean up the contacts and see what happens. Poor battery V and crappy connections can make for strange problems. Whatever is left we can figure out later

OK. Thanks. Will replace battery first then. I want to also replace the terminal cable, since the clamp has been corroded. I cannot find any threads about terminal cables, are those cables offered by advance auto parts good to go? I appreciate your help.

You don't need new cables, you can disconnect the clamps from the cables and replace just the clamps. Just about any of the clamps will work fine, but if you are worried about what works the employees at the parts store should be able to make sure you get appropriate clamps.

Poor battery connections can cause all sorts of problems, including trouble charging the battery, random warning lights on the dash, and battery damage (among other things). Corrosion on the battery terminals isn't something to take lightly or ignore.

OK. Thanks, I have cleaned the terminal, and sprayed some battery terminal protector, seems like I need to replace them then. Will update this thread when I replace the clamps and battery. Thanks a lot.

Just replaced the battery, after resetting DSC and warming up the car, in 15 miles drive, CEL the P0113 code showed up with 2-3S charging system light on then disappear and DSC light on and stay until next time I start the car. Can anyone give me some hint what to do next? Thanks

That leaves you the wiring harness...and the PCM circuit

OK. Thanks, I am not sure whether the test I did at parts store is adequate or not to say the alternator is fine though. Does anyone know where I can find out something to teach myself how to inspect harness and circus thx? I have the work shop manual but lack of knowledge of basic about electronics.....
