The EGS control unit detects the selector lever position by way of a switch on the transmission. This switch converts the current selector lever position into a code. This selector lever code is transferred via five lines (L1-L5) to the EGS control unit.
Selector lever position  | 
	L1 to L5 (0 = open, 1= U-batt)  | 
|---|---|
P  | 
	L1 =1, L2 = 1, L3 = 1, L4 =0, L5=0  | 
R  | 
	L1 =0, L2 = 0, L3 = 1, L4 =1, L5=0  | 
N  | 
	L1 =1, L2 = 1, L3 = 0, L4 =1, L5=0  | 
D  | 
	L1 =0, L2 = 0, L3 = 0, L4 =1, L5=1  | 
4 (3)  |
