•
Is the resistance between 28,000 and 34,000 ohms?
B6 CHECK OPEN CIRCUIT VOLTAGE OF BATTERY MODULE
•
Measure the voltage of the battery module(s) in question. Yes = GO to B7.
•
Is the voltage less than 10.5 volts?
No = Battery module OK.
B7 INPUT BATTERY MODULE DATA
•
Remove the traction battery (if necessary) and connect Traction Battery Yes = REPLACE the battery
