Trouble shooting

Can anyone help me to repair a Komatsu electric forklift model FB25EX-11, as it is not working
The main contactor is not energizing and display is saying "FAILURE IN CONT. (T) E04. No idea whether it is contactor or controller, as we don't have service manual.
Appreciate your help with a copy of service manual or atleast the troubleshooting section with wiring diagram and error code descriptions

Kindly help
