Circuit Description
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
The ECM receives signals (P, R, N, D, 4, 3, 2 and L) from the park/neutral position switch. When the signal is not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in D position.
When the shift lever is in the M position (with E-shift main switch for D and M pressed), "M" in the shift position indicator light will come on and when the shift lever is in the D position (with E-shift main switch for D and M released), "D" in the shift position indicator light will come on.
When the shift lever is in the L position (with E-shift main switch for 2 and L pressed), "L" in the shift position indicator light will come on and when the shift lever is in the 2 position (with E-shift main switch for 2 and L released), "2" in the shift position indicator light will come on.
When the shift lever is in M position, the ECM prohibits shifting to 5th.
