replying to my own thread. all issues resolved Ancel JP700 correctly read the codes which pointed to MAF sensor; I replaced that with a Denso MAF and now everything runs well. Cheers, Mark

1) I have heard that the later model year head units have full bluetooth / music over bluetooth capability, can anyone confirm? 2) Is it possible to simply swap in a 2007/2008 model year head unit into a 2003 alphard model year?

I bought this unit and it worked flawlessly with my 2003 hybrid. ANCEL JP700 https://www.amazon.ca/Ancel-Automotive-Japanese-Vehicles-Scanner/dp/B07B8FV26L/ref=sr_1_16?hvadid=600206609691&hvdev=c&hvlocphy=9001441&hvnetw=g&hvqmt=e&hvrand=13145785724962690394&hvtargid=kwd-337951665720&hydadcr=1320_13509211&keywords=ancel+obd2+scanner&qid=1684857021&sr=8-16

Any resolution to this issue?

Are Toyota vbelt CVT's repairable/rebuildable? or replace entire unit type of thing? I noticed that your newer alphard has a vbelt CVT as well. I thought all CVTs after the 2002-2007 alphards model year were planetary gear type, and not the vbelt type.

Paul, thanks for your reply. Regarding 2) I have additional information. By chance, I found a spare ELM327 that connected with the ECU with both Torque Pro and Car Scanner. Engine and sensor readouts seem to be populating, but neither app could find any error codes, even with a Check Engine Light on and CVT acting up. Any ideas? Could this be normal? Not sure how to interpret this other than the ODB2 reader isn't fully compliant. The customization string for Torque Pro seem that I provided earlier was not needed; possibly made things worse in my brief testing (reported a negative/incorrect coolant temperature).

I'll reply to my own message regarding 2) since I have found more information: More sucess from forum members with the 3.0 verison, less with 2.4 version, and only 1 post I could find regarding a 2.4 hybrid ATH10W. Based on what I read here, Success varies with ELM327 bluethooth adapters because it is suspected because cheaper/knockoff units do not have a required chip/function to read our JDM vehicles. In the case of using Torque Pro as the app with a fully functional ELM327 adapter, Some have reported a need to enter an additional string code. Others make no mention of a string code. In one thread, a poster stated the following string was used for a 2003 2.4 alphard (non hybrid) and worked: ATIB 96 \n ATIIA 13 \n ATSH8213F0 \n ATSP4 \n 0100 Others stated that they had success with using Car Scanner ELM OBD2 App by 0vZ with the ELM327. The following Profile was used: Toyota JOBD JDM CAN Multiple reports of success with the 2.4 Alphard (not sure if hybrid is included) and an off the shelf ANCEL JP700 JOBD OBD2 Japanese Car Scanner. No details as to if any customization or profiles used... or if it just works. Please add more information if you have it. Thank you.

Hi all. New owner of an ATH10W here, and I am experiencing problems right off the bat. I apologize if this is a reoccurring topic but I could not find anything to do with my issues on this subforum at all. Hoping for some advice and shared experiences regarding: 1) The CVT is slipping and surging under load. Seems to be worse when vehicle warms up. Very notificable surge/slip/stutter when going up hills when I reach 20mph, 40mph. Goes away when hill is gone and engine is not under load. CEL is triggered, but I am unable to read what code is triggered. Seems to lose power and vehicle wont accelerate very well. I am not sure it is related to the CEL, and if it triggers a "safe" mode to protect the vehicle. I did a CVT drain and refill on my way home from work today but not sure how much fluid was actually replaced (even though I had asked that they check for me). 2) What is the code reader of choice for our vehicles? I have an ELM327bluetooth+phone but connect to the ECU no matter what profile I use with the "Car Scanner ELM ODB2" app. Anyone have success with the ELM327 and another app combination? Hoping for some good news. Thank you all.
