Just Bought First Lexus - Is300 Sportcross

[n1tr0_9]

Hi,

just bought my first Lexus. Its a 2002 IS300 sportcross. I love it, but it has a few problems already. On test drive it ran perfect, no warning lights or other issues. After 3 days in my possession the radiator has started leaking, the manual mode / e-shift on the gearbox has stopped working, and now the TRC OFF and VSC warning lights have come on!

Googling all the faults is how i found this Forum. So i will be having a good read to see if i can fix these issues because i absolutely love every other aspect of the car.

Bought a new rad for £75, auto gearbox fluid £65, auto gearbox filter £105, sealer, drain plug crush washer, coolant etc etc. Lexus ownership is expensive.

Probably best to have the OBDII codes read for the TRC problem although wheel/ABS sensors have been known to cause this.

Good price for a radiator but Toyota ATF is expensive for 5 litres but don't use anything else, may have been worth seeing if there were any transmission codes logged before splashing out on fluid and filter.

I had the TRC and VSC lights up on my is 300 done an obd check and the fault came back as a misfire on number 1 cylinder needed new plugs and leads. Hope this helps.

Did a check of the codes. I had 3 errors logged. Bad signal from maf so I have cleaned it. Also solenoid A in gearbox in transmission error and turbine speed error. So I dropped gearbox sump and pulled solenoid 1 which I guess is A? I bench tested it and it opens and closes when energised. So must be wiring. I then unplugged, attempted to clean, and then reconnected all the connectors I could find on the gearbox. Hopefully this sorts it.

Hopefully what you have done will solve the issues but also check to make sure all the earth straps and -ve Battery connection are non-corroded and tight.

Good idea I will check those tomorrow
