Cathodic protection voltages are used to resist the damage to pipes or cables from electrolytic effects. The shift point learning-correcting unit executes learning-correction of a shift point during an upshift such that an input rotational speed of the automatic transmission reaches a predetermined target maximum rotational speed. The guide pins are held in sleeves of a supporting plate and are fastened to a steering wheel cover. The multiplexer multiplexes the first and second modulated signals and outputs a multiplexed signal.
