I need help!!!!!

No,

OBDI did not exist in the 1994 model year. There is no data port in a 94 for an OBD reader to hook up to.

The only thing you can hook up to a 94 is the Toyota scan tool. Those things run about 4,000 bucks and you don't get much more out of them than you do with a paper clip.

I will start searching the threads for how to check codes on a 1994 LC. Thanks for the info.

You need a paper clip or other suitable jumper. Open the hood and locate the data link on the RH side of the firewall, near the wiper motor. Open the cap and place your jumper in the "TE1" and the "E1" terminals. Turn the ignition on (do not start) and count the blinking light pattern of the check engine lamp. For example a code 21 is blink, blink, pause, blink, a longer pause and it repeats.

A steady blink with no pauses indicates that there are no stored trouble codes.

cruiserdan, thanks again! I will check it out tonight and may be asking for more advice (I will continue to search the board before asking!!!)

Dan is this the same method used on a 91. I tried this (?) but could not get it to work and my mil is on steady. What I tried was from a friend of mine Snap On code scanner's book, he does not have the toyota connector so this is what his book said to do.

 

[cruiserdan]

Yes, same procedure.

No need to check it Driley, you'll find that you have a code 21. You see, you've been tapped as Dan's place to store his knitting needle.

I feel your pain.

The pursuit of knowledge sometimes comes at a price... Thanks for your kind words and it was a code 21...

No problem. PM Doug for the head gasket video. Of course there's always the option of "feeding Dan's dogs" which might allow you to skirt by for a few months. I believe the code 21 points to O2 sensors but those are low dollar items and won't even feed those mangey mutts for two days.

You'll have to wait until he stores the needle somewhere else like .... in a white '97 LX450 with duraliner instead of flairs. (just a guess. )

I thought that code 21 was oxygen sensors. (just read your edited reply). But why a head casket video? You've lost me...

Was that a freudian slip?

Kinda depends on where Dan decides to shove the needle if you get my drift.

[Driley]

Gasket...not casket! Sorry. I did check the code again and got a 71. Pulled the EFI fuse and will see if it comes back on. LC running just fine and will probably wait until problems start before changing the egr sensor.

So does this mean that a stealership won't be able to pinpoint a problem any closer than my trusty paperclip on my 94? I am asking because we had a mechanic look at my truck and he that everything he looked at was functioning properly and that I should have the dealership read the code on it, even though we showed him the paper clip method. I am still stuggling with silly truck. I don't know why it has to malfunction right at Christmas.

I'd rather use a Toyota scan tool than others out there. Looking forward to Second Gen..........
