Check Egnine Light On

[bing56]

The check engine light of my '95 LS400 just turns on.

I need help to diagnose this problem. What should I check ?

Thanks,

Get a jumper wire and go to diagnostic port in the engine compartment (lift cover and it will show what the terminal names are), jumper TE1 and E1 ( with key on), read flashes from your check engine light ( the first series of flashes will be your first number, second series will be second number), this will translate to a code number (eg. 55), look up code in repair manual and the manual will tell you what to check from there.

Thanks for your prompt reply.

I tried the recomended reprocedure but do not see the check engine light flashing (jump TE1 and E1 terminals).

I did make sure that the jump wire is all the way in but no effect.

Did you turn the ignition switch ON after you put the jumper in?

Curt,

I did the following 2 combinations:

a1. Install jumper wire to TE1 and E1 terminals

a2. Turn key on

b1. Install jumper wire to TE1 and E1 terminals

b2. Turn key on and start engine

No matter what I do, the check engine light stayed lit and NOT flashing.

You might try sending VMF a PM, I think he has a 96 and somewhere along the line, the procedures for using diagnostics changed and I'm not sure where the breaking point is. I think VMF might be able to give you better advice, my car is a 93 LS and the pins you are jumpering are the right one for a 93.
