|
Main Switch Circuit |
DESCRIPTION
When the blind spot monitor main switch (warning canceling switch assembly) is turned on, a signal is sent to the blind spot monitor sensor LH and the blind spot monitor indicator on the blind spot monitor main switch (warning canceling switch assembly) illuminates. The blind spot monitor system operates according to this signal.
