CORRECTIVE ACTION
Error Code 213 - Tophandler Right Twistlocks
Indication Failure - Continued
a. If voltage is present,
perform functional check
of right side twistlock
proximity
switches
by
placing a metal object
within 5 mm of tip of each
switch. Proximity switch
indicator
light
should
illuminate.
If indicator lights do not
illuminate, replace proximity
switch (WP 0074 00).
b. If
indicator
lights
illuminate, check voltage at
junction box X184 pin 5
(for unlocked) and pin 6
(for locked).
If voltage is not present, replace
proximity switch (WP 0074 00).
5. Remove cover from junction
box X182 (located on top of
tophandler). Check voltage
between junction box X182
pin 4 and pin 5. Voltage
should be 20-25V.
If voltage is not as specified,
repair or replace cable from
junction box X183 to connector
X182 (WP 0111 00).
6. Check continuity between
junction box X182 pin 12 and
junction box X184 pin 5 and
between junction box X182
pin 13 and junction box X184
pin 6.
If continuity is not present,
repair or replace cable from
junction box X183 to connector
X182 (WP 0111 00).
7. Disconnect connector X181
from tophandler junction box
located at end of boom. Check
voltage between junction box
pin A and pin B. Voltage
should be 20-25V.
a. If voltage is not as specified,
repair cable from connector
X181 to junction box X182
(WP 0111 00).
b. If wiring harness must be
replaced,
notify
DS
Maintenance.
8. Check continuity between
junction box X182 pin 12 and
connector X181 pin G and
between junction box X182
pin 13 and connector X181
pin H.
a. If continuity is not present,
repair or replace cable from
connector X181 to connector
X182 (WP 0111 00).
b. If wiring harness must be
replaced,
notify
DS
Maintenance.
