Checking for codes, is it the same process as the Supras? Options

[NgoFcukinWay]

So on the way home from the movies last night, the car's CEL comes on for about 10 seconds and I nearly shat myself cuz this is the second time it's done this in a month.

Ok, so I know that with the MK3 Supras, you find the diagnostic box under the hood and connect lines TE1 and E1 together with a paper clip, turn the key to the on position and watch the CEL blink however many times to see what codes the ECU is throwing. I'm assuming I can use this same process on the Celica?

Is there a list of what each number means or will they be the same as what the Supra's TSRM have listed?
