Troubleshooting 

F0026 (Fault Reason 4, 5, 6)  

Error Description 

Possible Causes 

Possible Solutions 

BMS has detected an 

undervoltage in one or more cells. 

1)  Temporary undervoltage or 

voltage imbalance. 

 

1)  Allow ESS to rest, then 

change vehicle to 100%. 

 

Fault reasons 4, 5, and 6 are numbered in order of 

increasing severity. If fault reason 4 is raised, the 

high voltage power will be limited to 50%. If fault 

reason 5 is raised, driving will be disabled. If fault 

reason 6 is raised, the BMS will request the vehicle 

to shut down. 

 

 

Note:

 If requested during this procedure to 

connect the vehicle to a charger, a level 2 

charger is required. 

 

 

Note:

 Make sure HV systems are not in use 

while charging. 

 

 

Note:

 For best ESS performance and 

vehicle range HV batteries must regularly be 

changed to 100% SOC.  Vehicle SOC is a 

calculated valued that drifts over time.  It is 

recalibrated only at the end of the charge 

cycle when HV batteries are charged to 

100%.  Always fully change the vehicle until 

the charge cycle automatically ends.  Only 

charge vehicle using a level 2 or level 3 

EVSE.
