DIAGNOSTIC STATUS CODES

SX TRANSISTOR CONTROL

	TRACTION	DESCRIPTION OF STATUS
	STATUS CODE
	-67	The armature current exceeds the
	-67	armature transistor limit.
	MEMORY RECALL	CORRECTIVE ACTIONS
	YES	CORRECTIVE ACTIONS
	YES
		SYMPTOM
	Circuits valid	Control will not operate.
	Circuits valid
	for	POSSIBLE CAUSE
	Traction	• Shorted motor armature A1 to A2
	Traction	• Power cables may be shorted to each other
	Controller	(Measure at control terminals)
		• A1 to A2 terminals may be shorted to battery
		positive or negative
