Hy.I'm Adrian.I have a lexus is250 from 2006 and I just changed the battery and apear the VSC CHEK LIGHT and ENGINE LIGHT.and a c1201 and p2118 error codes.please someone can help with some suggestin


Code P2118 throttle control motor is set when voltage to the motor gets below 4 volts, so perhaps this was set with old dead battery. code C1201 is a vague engine control code, and the VSC vehicle stability code is set anytime you hook up a scan tool other that the dealer's special unit. You must reset the zero point calibration for this to go away. Use your scan tool to erase all codes to see if any come back. This will not turn off the VSC light, however. Follow below procedure to reset zero point calibration.

Zero Point Calibration - "VSC" and "VSC Off" Lights - 2002 SC430 - SOLVED
________________________________________
Friends,
For the benefit of any 2002 Lexus SC430 owners, I'll post the following item dealing with "Zero Point Calibration".
After hours of troubleshooting, I came to the hypothesis that the instructions MIGHT be different from 2002 - 2005 and 2006 - 2010 models. Below are the instructions I followed and WORKED on my 2002 SC430.
If you receive the "VSC" and "VSC Off" lights on the dashboard after a visit to a mechanic (often an independent mechanic using non-Lexus ODBII equipment), this means your "Zero Point Calibration" has been erroneously reset by a non-Lexus specific ODBII tool. This might especially happen if your state requires state inspection via ODBII, and you take your Lexus to a no-name place (like a Jiffy Lube or something). Follow the steps described in Post #6 in this thread to resolve this issue:
http://www.clublexus.com/forums/gs-2...d-vsc-off.html
Note that where you see a reference to a tool called the "SST 09843--18040", substitute that "tool" for a simple jumper cable (such as a short speaker wire) or a paperclip.
Here is the relevant excerpt from the above thread:
"The solution consists of approximately 15 step .
NOTE:While performing the Zero Point Calibration, do not tilt, move or shake the vehicle.
The vehicle must remain in a stationary condition throughout the entire process.
Be sure to perform the procedure on a level surface with an inclination of less than 1%.
Explanation of symbols:
SST (4-inch wire)
DLC3 (OBD-II connector under the dash)
TS (on the top row,pin number 3)
CG (on the bottom row,pin number 5)
(See picture below)
1. Ensure the shift lever is in the ''P'' range.
2. Turn the ignition switch Off.
3. Using SST 09843--18040, repeat a cycle of short and open between terminals Ts and
CG of DLC3 4 times or more within 8 seconds (refer to the specific vehicle EWD for
TS and CG pin location in the DLC3).
4. Turn the ignition switch ON, do not start.
5. Verify that the VSC indicator light is lit indicating the recorded zero point is erased.
6. Turn the ignition switch OFF.
7. Be sure the terminals Ts and CG of DLC3 are disconnected.
8. Turn the ignition switch ON, do not start.
9. Check that the VSC warning light goes off about 15 seconds after the ignition switch
is turned ON.
10. After ensuring that the VSC warning light remains OFF for 2 seconds, turn the ignition
switch OFF.
11. Connect terminals Ts and CG of DLC3 using SST 09843--18040.
12. Turn the ignition switch ON, do not start.
13. After turning the ignition switch ON, check that the VSC warning light is lit for about
4 seconds and then starts quick blinking at 0.13 second intervals.
14. After ensuring the blinking of the VSC warning light for 2 seconds, turn the ignition
switch OFF.
15. Remove the SST from terminals Ts and CG of DLC3.
16. Drive the vehicle for at least 5 minutes to confirm Zero Point Calibration is complete."

Why is battery draining ford 2002 Taurus SES


Remove negative cable from battery, connect a test light to negative terminal, opposite end off light to negative battery post. ( let sit for 3 to 5 minutes). Then start pulling fuses, when the light goes out that's your bad circuit. God-Bless! Its worth a try.

HOW TO REPLACE TRUNK LID STRUTS ON A 2002 LEXUS SC 430


I know, the video isn't an SC but it shows how you don't need that much room at the bottom. I have an 04 sc430 - love it but haven't had to change trunk struts yet. Good luck.

There are a couple of lexus forums that can be very helpful links beneath video...

You dont have to get them from LEXUS but in order to keep the sound at the same balance and quality, you should do that unless you want to replace all the speakers with other models.
