Re: 1993 LS 400. Trac malfunciton light illuminates after very short drive. What are the possible causes and what/how do I check them out?


To check them out you need the code read, After having a quick look the TRC light can come on because of the MAF failing, TRC ECU problems, and quite a few other things look here it tells you how to get the codes out and as yours will be pre OBD2 then you'll be able to get them with jsut a jumper wire
