Is there a way to read codes without the CEL on a 2JZ?

[destrux]

I'm trying to read the engine codes on a 2JZ-GE, but the CEL blub was taken out because it was "always lit up" :nono:. Is there another way to read the codes, like hooking a test light up to something in the check connector? I would pull the cluster and put a bulb in if it were my car, but it's not.

Thanks

If it's anything like the 7M, you cna use a multimeter (one with a needle works best) and watch the jumps. It's in the TSRM, but dunno where an online version for the 2J is.

I have the TSRM for the car, but it only talks about watching the CEL.

I didn't realize how easy it was to pull the cluster to change the bulb, it takes 5 minutes, so I went ahead and put a new bulb in the CEL. Problem is it still doesn't light up. Now I'm not sure if I have an ECU problem or what.

The car wouldn't start for the guy this morning so he had it towed to me.

So far I checked the B+ voltage in the check connector and the fuel pump voltage is good (which leads me to think the ECU is working, since it controls the fuel pump speed via the fuel pump controller). It would sputter a bit while cranking, but wouldn't start up and run.

The weird thing is when you turn the key to the on position the engine fires once and spins a little bit before you even engage the starter. I think the coil is firing when the key turns on and is firing whatever flooded cylinder happens to be on the compression/power stroke. Sometimes it even spins it backwards (which would happen if it fired on the compression stroke).

I tested it with a spark tester and it had no spark, but when I hooked my stuff up to test the coil the damn car started running. Then it stalled after 10 seconds. Now it fires up and then stalls shortly after.

I still have a few tests to try, but it would be a big help if I knew why the CEL didn't work.

So I found out that the W pin in the diagnostic connector is the CEL output, but with e1 and te1 jumped there's no output. Hrm...

a scanner hooked the diag box would work, but thats expensive for one of those, with the import software. normaly any shop will do it for a free and give you a print out.
