   Tester Connection	Condition	Specified Condition
   6 (IG) - 13 (S)	Shift lever position on S, "+" and "-"	Below 1 Ω
   5 (SFTU) - 11 (E)	Shift lever position continuously shifted to "+" (Up-shift)	Below 1 Ω
   4 (SFTD) - 11 (E)	Shift lever position continuously shifted to "-" (Down-shift)	Below 1 Ω
   6 (IG) - 13 (S)	Shift lever position not on S, "+" and "-"	10 kΩ or higher
   5 (SFTU) - 11 (E)	Shift lever position on S	10 kΩ or higher
   4 (SFTD) - 11 (E)	Shift lever position on S	10 kΩ or higher
