TRACTION	DESCRIPTION OF STATUS
STATUS CODE
-64	The line driver input (P2-17) is less
	than 12% of battery volts
MEMORY RECALL	CORRECTIVE ACTIONS
NO
	SYMPTOM
Circuits valid	Control will not operate.
for	POSSIBLE CAUSE
Traction	-Open wire connection to Pin 17
	- Shorted line Driver transistor
Controller	Defective control.
	• Replace controller unit.

CAUSE OF STATUS INDICATION

This status code will be displayed when the control detects that the line driver input (P2-17) is less than 12% battery volts when the key switch is turned on.
