Shift Position L Switch Circuit
CIRCUIT DESCRIPTION
The shift position L switch is a momentary type switch. When the shift position L switch is pressed while
driving with the shift lever in the 2 position, the L position indicator on the combination meter comes on and
the transmission is locked in 1st gear. When the switch is pressed again, the indicator goes off and the trans-
mission is released.
