Ok. Quick question

I have a bluetooth obd2 scanner

which works fine with newer cars using my android phone via bluetooth

my question is. If I buy this adapter


to connect it to my 87 22re pickup diagnostic plug, will it read anything?

thanks in advance

Almost certainly not. The protocols aren't even vaguely related.

So what is the adapter for? Beats me, and I own one.

Will not work, The OBD1 diag port on the Toyotas is a sensor and switch junction, Not a data port as OBD2 is.

No, the OBD1 port on our trucks IS a data port, it just requires some fancy footwork to read it. Fortunately, one of our members (RJR) has already done that: https://www.yotatech.com/forums/f116...reader-278801/

thanks. makes me wonder why would they build an adapter cable for it.

Some scanners (Snap-On MT2500 for one) have connectors and software cartridges for different vehicles. I regret the day I sold my Snap-On Scanner, didn't think I'd need it anymore.

My old MT-2500 scanner is a Godsend for the OBD1 Toyotas.

If you shop around for awhile on Ebay, you can get one with suitable cartridges and adapters for a couple hundred bucks. I run several different make pre-1997 non-standardised OBD cars and I don't know what I'd do without my old 'brick'.

They cost a bundle, back in the day.

No its not, You cannot pull any codes from the Toy OBD1 port, You can only jump it and read the ENG dash light.

I guess that you have never used a Snap=On MT2500 on an OBD1 Toyota.

It not only can read the codes, but the software contains a database of what the codes mean.

It may be true that the earlier OBD1 ECMs can give less info than the newest OBD1 ECMs can. I seem to remember differences between what can be got from my '87 and what can be got from my '95 truck.

I even read the TPS output on my '95 Runner and adjusted the TPS using my scanner.

The MT2500 will read codes on just about everything out there. Even the 80's Fords that you were supposed to check codes with an analog swing voltmeter.

It's not cheap

I paid $2k new almost 25 years ago. Had to have it, worked in a diagnostic shop and the Allen test POS wasn't cutting it. If you work in a shop it's a good investment.

Wow! Uh, not really ....

You don't need a $2,000 (or a coupla hundred) scanner. All you need is a $6 multimeter (you have that already) and the manual (here you go, for free: http://personal.utulsa.edu/~nathan-b...34electron.pdf)

A scanner is nice, mostly because you already have it and know how to use it. But for me, I'm not going to spend even a coupla hundred bucks on a "magic box." I would prefer to know just what signal I'm reading and what it really represents.

Plus, I'm cheap.

It's really nice when you take a road test and can watch the scanner data in real world driving conditions. It paid for itself many times over. But like I said, if you work in a shop it's a good investment. I sold my Scanner and bought a cheap $20 code reader because I'm retired and have no use for it now. The MT2500 also had the code diagnostic procedure, no FSM needed.
