The engine will always start up when cold before switching to hybrid mode, does the engine turn over when trying to start? The first start from ignition off is by the gearbox motor/generator so that could be an issue or the inverter if the engine does not turn over. Any codes?

You need to obtain a Certificate of Conformity, CoC, from https://japaninspection.org/certificate-of-conformity-coc/ not Toyota. You fill out a couple of forms and email them back, if they can find the export cert for you Alphard they will be able to issue a CoC after you have given them some money, cheaper at the moment because of the exchange rate. On the CoC will be the emissions details and a statement that it complies with Euro 4 standard. Send a copy of the form along with your V5 to DVLA with a cover letter asking them to update your V5 with the emission details, they will also add your engine s/n. The lez's will only take the info from the DVLA so once your emissions are updated the various lez's will update your vehicle, including London ulez. 2003 Toyota Alphard 2.4 hybrid.

You can get code readers specifically for Japanese vehicles which can read JOBD format data, an ODB2 will not work. Ancel and iCarsoft make these and there are others as well. I have an iCarsoft which will read hybrid data but I tend to use Techstream as it is easier to view all the parameters on one screen, you just need a Mini VCI J2534 Cable to connect laptop to the ODB port.

Because of where the horns are located they corrode as do the connectors , check the power supply at the connectors with the horn pressed also the earth point. Replacement horns on Amazon or ebay, just generic two tone horns. Check the fuse and horn relay which are both in the engine bay main fuse/relay box. If you can earth pin 2 on the relay that will bypass the clock spring sounding the horn.

I have 2005 hybrid. I bought an ODB to USB cable with Toyota Techstream. I think this is the only diagnostic tool you can get for series 10 hybrid. Found this on Amazon.
