Shift Indicator: Description and Operation
Circuit Operation
With the starter switch in ON or START battery voltage is applied to the automatic transmission mode switch and the A/T shift indicator control unit
from fuse C-3. The automatic transmission mode switch sends a signal to the A/T shift indicator control unit corresponding to the gear selected. The A/T
shift indicator control unit applies voltage to the appropriate A/T shift indicator causing it to light up.
