Second Gear Lamp

Second Gear Lamp


The PCM supplies 12 volts to the second gear start switch through a pull-up resistor. The second gear start switch is a normally open switch. The PCM senses a high input voltage, commands normal transaxle shifting, and the second gear start lamp is not illuminated. When the second gear start switch is closed, the input voltage to the PCM is pulled low. The PCM turns the second gear lamp ON and commands the to vehicle begin in second gear (the following gears shift in normal sequence).
