Hi MyanRagahis,
I had the very same trouble "Twice"; once when I first bought the truck, and just a month and a 1/2 ago... all fixed now!
After doing the
YAW Rate acceleration cali and the
Center point Steering Calibration, It's necessary (at times) to clear the DTC's stored in the ecu's history logs and temporary files.
If you don't, you may encounter further system anomalies as I did e.g., loss of Speed-o-meter, Tach-o-meter, key fob failure (or certification ecu), ABS light on, and worst of all, a TOTAL Charging system failure; the CAN-bus shut the
270-XP alternator down... that one cost me $85 bucks for a tow 1.5 miles from my house; ouch!
And I was paying for "Safety Connect" but they will only tow you to a Toyota Dealership! My truck is out of warranty, so I have NO USE for Toyota; especially because they didn't know to test my truck when it was brand new for a YAW Rate/Center point cali! So delete all of those DTC's out, "BEFORE" doing the calibrations again!
Here's the Instructions, just in case anyone else needs it... and you DON'T need a scan-gauge to do it:
Yaw Rate and Acceleration Sensor Zero Point Calibration
