Linus p thank you mate I'll give it a shot after work tomorrow. I'm wondering if the day time running lights would flatten the battery as when the IG is on they are constantly on whilst I've been trying to use techstream . In this part do you mean the car has to be on off sorry just confused as it says car has to be off and then next turn it to off lol ("The steps are as follows... car has to be OFF Short the pins, turn it to OFF>ACC>IG... DO NOT START THE ENGINE")

Does anyone have a diagram of the DLC pinouts please I'm trying to manually (paperclip method) recalibrate my steering sensor (techstream loses communication half way through 🤬) I've found lots of posts and videos online saying pins #4/#12 are the correct ones but when I use them it puts me in 'diag vsc' mode where I can check things on the navigation screen instead of test mode which is really frustrating 🤣 🤣 been trying for days 🤣

The mechanic came back this morning and checked and cleaned the connections still no difference since he's gone I've been trying to do the steering angle sensor on techstream but every time I get to the part where it asks for me to turn the wheel at least 90° it loses communication with the car. I really don't know what to do now lol. The mechanics tried everything he can do I myself don't have a clue 🤣

Thanks mate hopefully fingers crossed mine is the same I'm going to take it apart tomorrow and check every wire for damage and clean the connections and check they Clip in good maybe there's light at the end of the tunnel after all 🤣 cheers mate

Aww bloody hell lol I just tried the techstream and I can get into test mode and the lights flash but the video I was watching had to press the crawl control button to finish but mine doesn't have that button 😞

I'm going to finish my cuppa and go down and try re callibrating the sensor. I totally think that the wiring is damaged too I'm going to try techstream if not look for a new wiring harness hopefully it's a simple swap

Hiya mate I'm not to sure as I left him to it he was meant to come back today and hasn't (gutted a simple o2 sensor changed has already cost me 400+ with days off parts and labour 😡) I've spent all morning trying to install techstream I've finally managed to get techstream working and connected to my car and got the code C1515 which I found is zero point calibration so going to look into this now and see if theres a way I can callibrate it using techstream

Should I clean them aswell I did ask if he put the clips in and he said definitely

Thanks buddy that does make more sense to me 😎

Hi guys my is250 was feeling a bit sluggish and got CEL with code p0174 so I bought a denso O2 sensor and had a mobile mechanic fit it for me Friday (bank2 sensor 1) it was done by taking the battery out for access. After he left I then went to take my kids home and noticed the red p/s symbol and then realised I had no power steering. I understand the power steering module is under the battery. The mechanic came out again today but he could not do it ( I had to get my mum to come here for him as I had to be in work so wasn't here at the time). I be spoken to him and he said that my angle sensor needs resetting but his computer wouldn't let him do it but he will come back tomorrow and try a different computer My questions is does this seem right? The mechanics a decent guy he's not a cowboy and he fitted my fuel pressure sensor for me a couple months ago with no problems It's just my luck a simple o2 sensor has now left me without a car for 4 days I really need it for work badly especially with Christmas coming up and have to take another day off tommorow and Tbh I don't even think this is going to work sorry for the essay lol Cheers guys

That's true the pages are full of scammers and American kids asking why they're car is so slow 🤣

For sure mate I see people post on the is250 Facebook page with these symptoms all the time so it must be a common problem hopefully it helps a few people out this forum is amazing everyone helps each other out which I like

Yes mate loving life gunna get her cleaned after work tomorrow put air in tyres etc then I can finally enjoy it 😎 I showed the mechanic your advice and from another thread and he did it just like that

Linus I just wanted to say thank you again for helping me and the other forum member too thanks guy got a mechanic to fit a new sensor for me today and it started up straight away so happy guys been weeks walking and taxis everywhere

I checked with lexus mate and unfortunately no recalls for my vehicle gutted:(
