STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-151
Capacitor volts are low before the line
contactor closes. (Internal card function
during precharge)
This status code will be displayed during “key on”
when the capacitor volts is less than 85% of battery
volts at initial key switch on.
MEMORY RECALL
NO
CORRECTIVE ACTIONS TROUBLE-SHOOTING DIAGRAM
Circuits valid
for
Pump
Controller
SYMPTOM:
Line contactor does not
close when Capacitor does
not pre-charge.
POSSIBLE CAUSE:
Defective control fuse.
•= Check control fuse for
open circuit, replace fuse,
if necessary.
Defective control.
•= Replace controller unit.
Note: Repeated
charging/discharging the
