input too high
The truck won’t travel. Turn the key switch OFF. 26 51
W-phase current offset abnormal, AD
input too low
W-phase current offset abnormal, AD
input too high
The truck won’t travel. Turn the key switch OFF. 27 51
217
Rapid charging of capacitor abnormal
(Improper charging of the capacitor
between the P and N terminals)
(Error Codes 218 and 418 also occur.)
The travel, load handling, and PS (power
steering) systems are inoperative.
Contactor OFF.
Turn the key switch OFF. 23 52
218
Drive motor inverter unit upper/lower
FET short-circuited
(Error Code 418 also occurs because
the drive and load handling units are
connected with a copper bar.)
(Error Code 217 is also triggered because
the capacitor between the P and N
terminals cannot be charged.)
The travel, load handling, and PS (power
steering) systems are inoperative.
Contactor OFF.
Turn the key switch OFF. 15 52
