If the result is not as specified, replace the turn signal switch.

HINT:

  • The left turn or right turn condition indicates a condition in which the turn signal switch will return to the neutral position after releasing your hand from the turn signal switch (turn signal switch is operated approximately 6.3°).
  • The full left turn or full right turn condition indicates a condition in which the turn signal switch will not return to the neutral position after releasing your hand from the turn signal switch (turn signal switch is operated 10.5°).
