CORRECTIVE ACTION
Error Code 255 - Tophandler Clockwise
Slewing, Wiring Circuit 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
6008
from
tophandler clockwise slewing
solenoid.
Place
ignition
switch to ON position and
perform voltage check.
If 20-25V is present at connector
6008, replace clockwise slewing
solenoid (WP 0169 00).
3. Disconnect connector X188
from tophandler junction box
at end of boom. Place ignition
switch to ON position and
perform voltage check at
connector X188 pin A and pin
B.
If voltage is not present, repair or
replace connectors (WP 0111
00).
a. If 20-25V is present, check
continuity between con-
nector X188 pin A and
connector 6008 pin 1;
between connector X188
pin B and connector 6008
pin
2;
and
between
connector X188 pin B and
ECU (791) connector 3 pin
3.
a. If continuity is not present,
repair or replace connectors
(WP 0111 00).
b. If wiring harness requires
