Inactive Code

Recommended Posts

I am currently trying to find out what it means to have an inactive code of 9-2 CODE J-1939. The truck is a 2003 Mack CH613. Please advise the meaning of this code.


It means the truck electrical system lost power while the ignition was still on. Happens a lot with loose battery connections or bad batteries and also if a master battery switch is turned off before the VMAC system powers down.
