1 (RB) - 2 (RL)	Shift lever in R	Below 1 Ω
1 (RB) - 8 (NL)	Shift lever in N	Below 1 Ω
1 (RB) - 7 (DL)	Shift lever in D, S, "+" or "-"	Below 1 Ω
4 (B) - 9 (L)	Shift lever not in P or N	10 kΩ or higher
1 (RB) - 3 (PL)	Shift lever not in P	10 kΩ or higher
1 (RB) - 2 (RL)	Shift lever not in R	10 kΩ or higher
1 (RB) - 8 (NL)	Shift lever not in N	10 kΩ or higher
1 (RB) - 7 (DL)	Shift lever not in D, S, "+" or "-"	10 kΩ or higher
