I am stuck with one of Komatsu Forklift. It is giving Error 69 on the Display unit and Steering Symbol also shown on the Display unit and hence the Steering motor is not allowed to turn the wheels. What is this Error code 69 stands on Komatsu Forklifts.

Hey Julis, I believe that it is something else.
FE65, Wire breakage at the output for the electro-magnetic brake
When the brake is driven (clocked), the LAS module monitors this clocking process, i.e. the continuous 1/0 change is checked internally at output X10.3 (closed brake circuit, no wire breakage).
If this is not the case, the system recognises this as wire breakage. The LAS module stops issuing the "Brake released" signal (X10.23) to the FPS. This means that travel is blocked.
Check the wiring and brake (see "LAS module, Checking the electro-magnetic brake").
I'll this will help you further
