Techstream / GTS+ questions, answered
Is GTS+ the same as Toyota Techstream?

Can a Toyota or Lexus software update fix a warning light?
Only if an applicable update addresses the diagnosed condition. Send the codes, symptoms, and any bulletin reference. A flash cannot be assumed to repair a wiring fault or failed component.
