Question about Lexus SC 300

1 Answer

On my 1992 lexus sc300 the tracking off light comes on (even though the tracking is on) and a picture of the engine appears beside it. It has only done this once so far in heavy rainey weather. After I drive for a bit it goes off. What's going on? I ask a mechanic (at a local gas station who had no diagnostic tools when it happened. He said it was because it was wet. It happened again later that day when it was a dry road as well but again went off after a few miles. This was the day it had rained like crazy and the car was soaked. could it be that the car being old, just had a minor short from all that rain? Will it mess up anything if I dont immediately spend a fortune to get it diagnosed. If it doest happen again can I safely drive the car till I can get it fixed ? Or is it something I must worry about and get it fixed A.S.A.P? Please help. And than you for your response. P.S. I am unemployed and need the car to look for work.

    Thank you for getting back to me. At least I know it wont break down. I dont know if I can ask another question since I only paid the lowest amount. But hear it is if you can. Would it help if I switch off the tracking when I drive the car. Kind of by passing the tracking by turning it off? And if you could may be give a guess as to how much it may cost to get it checked out?

    Thank you so much

1st this is not dangerous and you can drive the car. Next the repair for this will be very expensive, you will need to take it to a dealer for further diagnosis and testing, when these warning lights come on they set a fault code in the computer control module, until you know the code that is in memory you are just guessing, it takes a Lexus dealers special scanner to check the system, oslo expensive. My advice is just drive it, it will not break down and in fact you may not feel any difference in the way the car operates.

    Whenever the TRAC warning light is on the system turns itself off until the problem is repaired, so need not do anything, it is all automatic.

    If the system has an on/off switch yes turn it off.
