Traction Control/CEL trouble, please help
Hi guys,
So I recently purchased a 91 LS400, and I have a few questions about issues Im really concerned about. To tell you a little about the car, Its sitting on Megan coilovers, and it IS slammed... the frame itself is sitting about 4-5 inches from the ground. Now, just recently, the TRAC light started to come and go, and whenever it did, it also threw a TRAC OFF light, as well as CEL light.
Like I said, the lights come and go, I dont know if its due to the ride height of the car, or the fact that the back is a little higher than the front. I erased the codes using the OBDI code clearing method, using a jumper, and simple wiring skills, but the lights came back after a short period of time. I also must mention that when all teh lights are on, the car will NOT downshift into lower gears to speed up, Ihave to manually shift it into O/D, 2nd, oreven 1st.... I'm concerned about the amount of money I might have to spend in order to fix this issue. A friend told me that theres a module out there which tricks the traction control to stay on or off or something...
I'm in desperate need of help... Thank you

Thankks for the replies. I fixed the issue. Just recently before I fixed it, I actually had a lot more warning lights come on right before I fixed it. I had a "battery" light, "brake" light, "add coolant" and "add oil" lights, as well as the "taillight failure" lights. One day I was driving the car, and it gave signs of low voltage in the battery. I decided to do a random alternator test, by pulling the positive(+) battery terminal from the battery while the car was running, and the motor shut off... this lead me to believe that the motor isn't making enough voltage to stay on by itself (blown alternator), so I had my mechanic knock the issue out.
Been driving the car for 2 days now, with no warning lights whatsoever. Drives perfect.
Also must mention that when the TRAC lights were coming and going, I also had a Check Engine Light, from which I pulled 3 codes, all relating to voltage issues.
Thx for the replies, appreciate the help
