OBDII Connector

[Meruv]

Hi Guys,

Anyone of you out there know where is the OBDII Connector located in a Prado LC (RZJ90L)?. I have searched under the dash around the steering column (left side) and behind the glove compartment (right side) with no success. I checked the Diagnosis connector in the engine compartment and it is different.

Any help would be really appreciated.

Thanks!

Meruv.

Where is your truck from? (Country where it was originally sold?)

What is the purpose of finding the OBDII connector.

To self diagnose a problem

To connect an aftermarket widget (eg scangauge)

I have a KZJ95 (Australian) and after e-mailing the scangauge guys, it turns out that my car doesn't have a OBDII connector and doesn't use OBDII

Perhaps yours is the same

It is from Toyota Colombia and sold in Venezuela.

Tnx.

Hi Dhula,

The purpose is to connect a Code reader and verify sensors, self testing, etc. Maybe you are right and for some strange reason this model does not have the OBDII connector. Or perhaps, it is so reliable it does not even need one!

Tnx.

OBDII is an American thing due to the California Air Resources Board. Some (most?) other countries probably don't use it.

There is Toyota diagnostic connector that you can use to read codes.

On my car (KZJ95 - 3.0 TD) if you bridge 2 of the terminals in the Toyota on board diagnostic (lets call it TOBD) plug then the engine warning light will flash a certain way to tell you if all is OK or not.

I'm not sure which terminals to bridge on your car (2.7l , 4 cyl if I'm correct ???????) but I'm sure someone on this forum will know and be able to post instructions for you.

That may get you out of trouble hopefully.

Perhaps you can send a PM to TEPUI. He has a manula that covers that engine.

Dhula,

It seems to be you are right. I can not find any OBDII (DLC3) connector in my car, only the Diagnosis connector (DLC1). In this case (according to a Toyota Service Manual) by grounding the TE1 circuit (to E1) you can get the DTCs counting the MIL flashes. It says you can also read the VF1 circuit with a VOM or with a scan tool using the W terminal.

Anyway, if anyone out there knows more about it, please let me know. I will continue researching.

UpsideDown,

Well, it looks like this is the case. I could not find any OBDII connector in my car, so far. Do you know how to use a code reader or scan tool with this Diagnosis connector (DLC1 type)? Or just have to live counting MIL flashes?

Tnx.

I use a Snap On scanner, but they are really set up for the North American market... and after 1996 they are all OBDII. I have not had occasion to use the Toyota connector on later models, though they are included on all the OBDII cars in addition to OBDII plug.

I'll have to ask the Snap On rep the next time he's here, I'd like to be able to scan JDMs and others. There must be upgrades available... Any Aussies or others here that use Snap On diagnostics in your home countries?
