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. 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 4 or “M” position, the ECM prohibits shifting to 5th. See Fig. 87 . Possible causes are: Open or short in Park/Neutral Position (PNP) switch circuit. Faulty PNP switch. Faulty ECM.
