You might try setting the correct protocol
manually. The auto search for protocol may
be causing the issues you describe.

Is your adapter showing errors under the
adapter status icon functions?

Have you checked for bent pins on the DLC?

Thanks for the reply.

ok ill check the status of the adapter etc...

sorry for being dumb but im new to this...

How would i find out what the correct protocol is?

cheers

You mentioned that your vehicle
connected fine at some point... look
under adapter status icon functions
to see which protocol Torque is using.

You might also check a forum specific
to your vehicle to see if someone
knowledgeable can answer.

I cant see any problems in the adapter settings.

The adapter connects fine and torque works correctly.

The problem is just the flashing lights on the dash.

its almost like the car detects the reader is plugged in and goes into a diagnostic mode.

Thanks

Hi.
Just a quick update. I've tried a different obd reader and get the same problem. I've tried different protocols as well. ( I've also found the correct one for the car) but the problem still happens.
The lights on the dash will start flashing even just with an obd reader plugged in never mind connecting to my phone etc..

I've found a video on YouTube of basically the same problem I'm having ( but the car in the video is an avensis)

I can take a video to show you if you like.
I'm not sure but from the comments on the video it looks like the car doesn't like pins 4 and 13 being connected.

Do I try disconnecting one of these pins ? If so which one ? Or do I disconnect both.

Hope you can help as this is driving me mad now.
Cheers

If your vehicle was sold for JDM... you might
want to look into using a custom init string.

I don't think an ELM327 adapter uses pin 13, but you could check by opening it up and looking at the back of the connector. I don't see any wires on pin 13 of the several adapters I have.
I do know that some 95 Toyota/Lexus models will both flash the old OBD codes and display the OBD2 codes using an OBD2 scanner. My father's 95 Lexus was that design. In the service manual it says to short two terminals in the circuit terminal block under the hood to flash the codes; and use the OBD2 connector under the dash to get the other codes. I don't know if that carried over to later years though. Perhaps the two OBD terminals were brought out to the OBD2 connector.

Thanks for the replies. Im guessing it isn't a problem with the protocol as torque is able to connect to the ECU and works perfectly.

Looking in the adapter status everything is OK and it connects to the ECU fine.

The only problem I have is the flashing lights on the dash. I'll see what pins are used on the elm327

Any more ideas ?

Thanks

Toyota on old issues is a problem in the derivation of 6 OBD2 connector, isolate 6 output from the adapter, as the 6 pin is used for self-diagnosis, and the adapter ELM327 6 and 14 terminals are shorted through a resistance of 120 ohms
measure the resistance tester contacts 6 and 7, they are short-circuited

Hi all. Just to let you know I have found the solution to this problem.

The problem is that the car uses the ISO protocol. But doesn't like the can pin being connected.

If you remove pin 14. Which as you look at the car socket is on the bottom row third from the right.

I simply removed this pin from the obd reader using a pair of pliers and twisting.

No lights now flash and everything works fine.

My problem is now that I found this out using a process of elimination and have butcherd my reader. Including accidentally removing the power pin which I'm now going to try soldering back on. Looks like I may need to buy a new reader.

Thanks for the advice tho.

I hope what I have found will help someone else with the same problem.

Cheers

Good job, Jon. It probably relates to what cintakc was stating also.
Depending on the type of ELM327 adapter you are using, you will be able to open the case and reattach some pins if necessary. If it is a mini version with 2 circuit boards stacked, then the task is complicated because the connector is soldered directly to the circuit board. If it is not a mini version, just poke through the corners of the label to remove the 4 case screws and open it up.

Also note that if you haven't bought an adapter lately, avoid the cheapest chinese-made ones. They have been skimping on parts lately, and all but the CAN protocols do not work for most of them. I think BAFX may be the exception.
