Error Code 259 - Tophandler Counterclockwise
Slewing, Component Failure
1. Check wires and cables from
tophandler control valve to
boom for obvious damage.
Repair or replace damaged wires
(WP 0111 00).
2. Disconnect
electrical
connector
6009
from
tophandler counterclockwise
slewing
solenoid.
Place

switch
to
ON
position. Error code 258 will
be displayed. Perform voltage
check.
If 20-25V is present at connector
6009, replace counterclockwise
slewing solenoid (WP 0169 00).
3. Disconnect connector X188
from tophandler junction box
at end of boom. Place ignition
switch to OFF position and
check continuity between
connector 6009 pin 1 and pin
2 and between connector
6009 pin 1 and pin 2 and
chassis.
a. If continuity is not present,
repair or replace connectors
(WP 0111 00).
b. If wiring harness requires
