Immobilizer Keeps Coming On (wont start)
2008 Lexus IS250. 100k miles
1) Recently Changed FOB battery as it was dead
2)Got the car washed, cleaners drove it back, when I tried to start it the next day it would only crank but not start.
Used my Tech Steam to pull up codes and it showed Immobilizer was on, great...cleared the code and worked like a charm for 50 miles or so. Parked again overnight and next morning immobilizer is back enabled and will not clear this time. Key is detected fine, side views illuminate when next top the car, doors unlock just fine with remote as well as when hand is on handle.
See attached errors. (VSC AND AFS has been on for months, can ignore them)
Also, is pinning 4&13 and waiting 30 minutes a safe way to reprogram ECU with this model?
