Machine condition
1. Machine condition CHK1
2a. Machine condition CHK2
Transistor output: 0 = OFF, 1 = ON
X: Not used
2b. Machine condition CHK5(was CHK2’)
In screen CHK2. when the travel mode switch is
pressed, the CHK2’ screen appears and windows TR1
and TR2 show any overloads in the corresponding
electrical circuits.
No overload = 0, Overload = 1
Example: In the screen opposite, windows TR1 and
TR2 show an overload on the swing brake and battery
relay circuit.
NOTE: In diagnostic mode, if an error code is changed
to zero, the data is also erased.
