After my mechanic changed my brake pads and the break wear sensor, he reseted the memory (by mistake) and now I'm getting the "Check VSC" warning. From what I've read, I need to do a Zero point calibration and I found something online that doesn't require any special tool but only a jump wire. For that I need to jump two pins in DLC3, which are TS and CG, and I got differrent opinions about their location in DLC3. So I'm looking to find a DLC3 diagram for 2003 LS 430, if anyone can help. Here is the instructions I found for the zero point calibration; any comments about this are appreciated.

******************************************************

Zero Point Calibration Using SST 09843–18040
The following procedure may be used in the cases where a Diagnostic Tester is
not available.
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%.
1. Ensure the shift lever is in the “P” range.
2. Turn the ignition switch ON.
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. Verify that the VSC indicator light is lit indicating the recorded zero point is erased.
5. Turn the ignition switch OFF.
6. Be sure the terminals Ts and CG of DLC3 are disconnected.
7. Turn the ignition switch ON.
8. Check that the VSC warning light goes off about 15 seconds after the ignition switch
is turned ON.
9. After ensuring that the VSC warning light remains OFF for 2 seconds, turn the ignition
switch OFF.
10. Connect terminals Ts and CG of DLC3 using SST 09843–18040.
11. Turn the ignition switch ON.
12. 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.
13. After ensuring the blinking of the VSC warning light for 2 seconds, turn the ignition
switch OFF.
14. Remove the SST from terminals Ts and CG of DLC3.
15. Drive the vehicle for at least 5 minutes to confirm Zero Point Calibration is complete.
NOTE:
If viewing Diagnostic Tester Data List after repair, the Steering Angle Sensor may
remain at 1150 until the vehicle reaches 28 mph. This is a normal condition until the
learned values of the steering angle have been achieved.

The SST 09843–18040 is ...the jump wire, any piece of wire you may find.
Here are two links with TS and CG in different positions:

Good evening Friends,
I had a wheel sensor replaced on my 1998 gs300, now I have the ABS VSC lights. Want to do the zero point calibration, can someone tell me where tthe TS and CG are. Are they 12 (TS) and 4(CG)?
