Can anyone help with error code diagnosis on my '95 SC400? My main problem is that TRAC lights intermittently when driving (sanely). I'm not sure ABS works either, but that is a side issue.

My diagnostic port is under the dash. I jumper E1 and TC to get:
TRAC code 43
ABS code 54
airbag and cruise flash continuously

Searching this forum, there seem to be different diagnostic procedures depending on model year and perhaps engine size. I read that the diagnostic port is either on the intake manifold (I don't see it) or under the dash (got it). I also read that E1 is to be jumpered with TE1 or TE2 or TC. The first two yield no codes, and only light the CEL and something else (cruise?) continuously. And I can't find mention of these specific codes.

 

TE1 and E1 only work for a Check Engine light.

So, what's causing these codes? Where should I start looking for the culprit?
