is in the LOCK (OFF) position, any abnormality in this signal prevents the
following functions operating.
DLights left ON reminder warning function
DPower window timer function
DHeadlamp automatic cut-off function
Or, the following functions operate when the ignition switch is in the ON position
only.
DDiagnosis code reading and input signal check by MUT-II.
