2008 onwards (may be the same as earlier?) Rubbers install.pdf Rubbers removal.pdf

Is that a 20 series 2008 vehicle? the wiring diagrams are coded EM08Z5E You can get PDF copies of them here: https://cardiagn.com/toyota-alphard-vellfire-em08z5e-em2441e-wiring-diagrams/ Even has the plug diagrams. Earlier models *may* use the same colouring scheme, I'm not sure if the looms are as identicle.

Not an expert on Hybrids, from what I understand, if the hybrid system has been functioning optimally back in Japan, i.e. it has been utilising the electric motors the majority of the time, it is possible that the cooling system for the battery is not working as it should - you may need to get access to the fan blower that keeps the battery/aux battery cool - if these reach a certain temperature, it will cut off the hybrid system. Coupled to this, is the loading of the Electric motors, could reduce the loading on the petrol engine - what condition are the spark plugs in?, and potentially the operation of the catalytic convertor at reduced heat levels could require it to be cleaned. I got this info from: https://www.fixmycar.pk/toyota-alphard-hybrid-e-four-2/ I think there may be some diagnostic info in the online maintenance manual I posted up a few days ago (its in japanese though)

Using the Japanese manaul i found online, this page details disassembly: http://fsm.japanclassic.ru/toyota/2002.5_7a037_alphard_anh1,mnh1/x339/servinfo/x33900001ap000k_base.html and http://fsm.japanclassic.ru/toyota/2002.5_7a037_alphard_anh1,mnh1/x339/servinfo/x33900000ci000a_base.html

AH, forgot the main thing... The website link.. I hope this helps someone, the main page has 5 coloured tabs at top, I think the 1st just reloads, 2nd is maintenance manual, DTC error code diagnostics etc, 3rd is feature list/instructions, 4th is wiring, 5th is engine/gearbox disassembly/rebuild. http://fsm.japanclassic.ru/toyota/2002.5_7a037_alphard_anh1,mnh1/x339/index2.html The original source appears to be from a technicians CD, if anyone wants to help dig to find out how to use this site better, or find the original source, thats great!

Wiring for the TEMS:

Anyone that knows me, will know I am a furious Googler. I know that it is almost impossible to find decent workshop manuals for the 10 series (1st Gen alphands) I have some news, I found something online, contains wiring diagrams, maintenance instructions, tracking measurements, etc etc. Bad news, its in Japanese, partially good news, you can use Chrome browser to auto translate chuncks of it. Example: Of Course, the diagrams are images, so do not auto translate, but you could submit these as an image search or use mobile phone camera to translate If anyone wants to try navigating this site, even with the minor issue of language, the diagrams themselves would prove useful, I think. Boot removal to access lamps, example:

I saw a youtube video on changing this switch - I think I recall that there are actually 2 switchs, one is for the break lights, one activates the selonoid that releases the gearshift and allows engine to start

Yep, side curtains running the length of both sides, also an additional 4 (i think) shock sensors mounted in centre and rear of car to assess impact velocity to trigger bags. I imagine a smack hard enough to trigger the side bags would probably write off the vehicle anyway, but you will probably get shards of furniture flying about dependant on the quality of the install. I imagine the conversion costs would have to take this in to account, to remove the bags and deactivate them from the system, probably would need to downgrade the SRS ECM to prevent it whining about the missing bags, and activating the warning indicator on dash. I think you'd have to really love the facelift and some of the modern electronics to make the 20series worthwhile. For me, the occasional rollmat if I need to catch some zzzz in the alphard is sufficient.

private import? if so, I know there are dealers selling copies the certs on ebay

Link to GTS (Global techstream) document with ECU/ECM firmware update instructions: https://www.toyota-tech.eu/td/ditabulletin/index.aspx?link=fi9OR0J1bGxldGluL0ctMDAwMlQtVE1DRU4vaW5kZXguaHRtbA%3d%3d

Techstream will communicate with the 30 series, its a standard tool on newer Alphards (2008 onwards) as well as most JDM Toyotas since around 2006 You would be well advised to just buy the connection lead/adaptor and a copy of techstream from ebay, should be under $50 AUS. I can even provide a link to the software pre-setup in a virtual machine, so no faffin about with drivers and software install/registration/compatibility with newer versions of Windows OS. In this way, even if you are not comfortable with diagnosis, you can bring a laptop with you to the service technician and show the status with a tool that actually works

Quick check on ebay, you can buy the complete arm and wiper for under £20. These look identical to the factory fitted ones.

You sure its missing? Is your alphard 1st gen? on 2008 onwards, the rear wiper is fitted under the roof spoiler, i remember 1st viewing mine and drawing air in over teeth, because I thought the rear wiper was not fitted, but then spotted it when checking the 3rd brake light was functioning (and the fact the wiper controller inside had 'rear' controls too)

Try also switching off auto 4wd and traction controls if you have the buttons to do so, limit the monitoring ECUs to try and limit the scope of the electronics that are preventing car from moving.

No one replied to this post to say if the problem was resolved, thats a shame. For a start, try disconnecting power to any speedo electronic convertors, to rule out the combination meter readings being a problem. How long have you had vehicle? DTC P0500 diagnosis.pdf I also attach diagnosis flow for an engine DTC P0500, as this appears to be the code mentioned in previous messages

if you get the chassis number you can get a carvx report done for about £15 - it will tell you the official regulated auction milage at point of sell in Japan

what gen alphard? On the 20series, I know that you can set via the buttons mentioned above, there is also setting in techstream to set the amount of dimming at night relative to the day setting.

duplicate post

Yeah, I read as many japanese catalogues as possible - the 2nd gen do not have swivel seats as an option at all. Not sure if it was a law/regulation change related to safety ratings, or if it is something to do with the SRS airbag setup in the 2nd gen, which seems more likely. Infact, as a point of discussion, do camper conversions have the curtain airbags disconnected? as this would seem a bad thing to go off in an accident if they are blocked from correct operation by installed cabinets

These ones are snug, fully encapulated too, so wont corrode, I have used these in an older Regius and in my Alphard, I have these bulbs in the front side lights, rear sidelights, numberplate lights and all my internal lights except the boot light, which is a different socket type. Pure white light and brighter than originals - I used a different type of led previously, they suffered from corrosion and started flickering and dimming after a couple of months, these ones seem to be doing well. https://www.ebay.co.uk/itm/382904669684 The price is for 10 bulbs, so I bought 2 sets and did whole car in one go (2nd Gen Alphard)

You could fit bulbs like these in to both reverse light sockets: https://www.aliexpress.com/item/32780015356.html Red when you switch fogs on, will override and turn off red and switch on white, if you select reverse, and of course white if you select reverse and your fogs are off. Have to run a positive wire up the rear frame and across down into rear boot/door panel, but alot more servicable and cheaper than the £100 lenses im currently trying to look at Similar bulbs are available elsewhere, these one provide about 1000lumen of white (combined 2 bulbs) or around 400lumen when red

No, these are not 'retroreflective' standard retroflective lenses are designed to reflect light 'back' in the direction it came from, upto 55degrees, whereas normal reflectors act more like mirrors, so the light reflects 'away' from the the angle it hits. I bought similar to those you listed to test, they shine if hit with a torch square on, but at an angle, they are dark. The little dimples you see are just micro lenses to shine light out better from the LEDs I attach an image from one of those types of fitment, in the image I stuck on a small retroreflector (the round thing) as you can see that is taken with a light source at about 45degrees off centre and it looks like the round thing is internally lit like a bulb, whereas there is only 'mirror' effect reflection in the rest of the lens

Well, they do state that it passes the ECE standard, and they are E marked, which means the retroreflector must attain a certain percentage of light reflected back to the source - from the images I see, the 2 halfs of the lens have the reflective prisms offset by at least 45degrees, which would indicate they have attempted to comply to both the ECE and SAE standards within one lens. Of course, i'm no expert, just someone that has probably wasted way too much time delving into UN and ECE regulations with respect to lighting! Still would be interested in hearing a categorical statement by them, i'm willing to pay this premium price if it means zero hassle from enforcement officers or testers.
