WALK5673 Posted August 20 Posted August 20 I have a 2006 3 Ltr Alphard with a problem. The battery went flat and I recharged it OK. When I came to start it it starts OK but there are three lights on "VSC", "Check Engine" and TRK off". The car I presume is in "Safety Mode" and will not respond to the throttle. I am assuming this is a computer problem (I hate computers). Can any of you guys help ? I have had the car since February and it is everything I wanted what a brilliant machine !

Hello Brian, Welcome to the Forum. If you bought from a business get in touch with them; possible warranty claim. Have you tried pressing the TRC button ? Do you have a smart charger. How old is your battery? I would get it tested under load. Halfords or Kwik Fit. You need a good battery on the V6 or all sorts of little gremlins will appear. You may also have a wheel sensor issue. Call your local Toyota dealer, most will not work on a grey import; but some will. They will be able to read the codes.
WALK5673 Posted August 21 Author Posted August 21 Thanks for the speedy response. I am an ex Marine Engineer and have always maintained my own vehicles until the computers came along. The lack of a maintenance manual is a major problem but I think the expertise and experience of people on this forum will more than make up for that. I am waiting for an OBD2 Scanner to read the fault codes. Do you know where the scanner port is on the car ?
Geralt Posted August 21 Posted August 21 Have you tried completely disconnecting the battery for 15 mins and reconnecting, full charged of course?
WALK5673 Posted August 21 Author Posted August 21 Thanks for the info Geralt. I thought about disconnecting the battery but am always wary of losing something in the computers memory. I suppose on this car the key is not programmed to the car so it should be OK. I will give it a try tonight.
Picasso Posted August 21 Posted August 21 Once you reconnect the battery you will need to reset your electric windows and sun roof if you have one
WALK5673 Posted August 22 Author Posted August 22 Update: Disconnected the battery for an hour, reconnected no difference I'm afraid. Engine is in "Limp" mode "TRK off, Check Engine Light and VSC lights on". My OBD2 Scanner should arrive tomorrow so I can scan the codes, will update again then. Thanks again for the assistance.
WALK5673 Posted August 23 Author Posted August 23 Update: OBD2 Scanner arrived, powers up OK but will not "handshake" with the computer (Is it OBD2 compatible?). I was hoping to clear the codes to get out of "Limp" mode. It looks like I need a mobile auto electrician.
Picasso Posted August 23 Posted August 23 Hello brian a basic odb2 scanner will read the engine light only thats probaly why it wont read your faults because engine light not on really you need some one who has techstream software this reads everything in the alphard maybe there is a member on here thats close to you with a scanner who can help you . im sure some one on here will help you.
Geralt Posted August 23 Posted August 23 You may need a JOBD scanner. E.g. Ancel JP700. My 2003 Alphard won't speak to my OBD2 scanner that I use for my beemer so I had to buy the Ancel as well. 1
Geralt Posted August 23 Posted August 23 In any case, my JOBD scanner only reads Check Engine codes. As Picasso says, to read non-emssions codes like traction control faults, you may need Techstream running on a laptop. It's not difficult but if you don't like computers, you might need assistance. 1
WALK5673 Posted August 23 Author Posted August 23 Thanks again Geralt. My son is the computer wizard and I have a spare laptop running Windows 10, I think I will give "Techstream" a try.
Geralt Posted August 24 Posted August 24 You're welcome. You also need MVCI cable. I bought this one which comes the Techstream software and some decent support from the seller: https://www.ebay.co.uk/itm/124808047632 Alternatively you can run a virtual machine version which doesn't need installation. This is the method described here: https://forum.ih8mud.com/threads/how-to-techstream-in-5-minutes.1034923/ I found this to work just as well as the installed version.
