Solution
21 Pri Boom
Up / Down
Joystick
11 Shorted
to
supply
voltage
Circuit C164PUD is
above 4.5 V.
Boom Up and Down
functions will not
operate.
* Leave joystick in neutral position
and cycle power.
* If fault persists, with a voltmeter
check that C164PUD (RD/WH, PCON
J18-3) is at 2. 5V +/- 0.2 V at startup
and does not go above 4.5 V or below
0.5 V when fully stroked in each
direction.
* Replace joystick if voltage check
fails.
28 Active
at
startup
Circuit C164PUD
voltage was not
within the startup
voltage range of 2.5
V +/- 0.2 V.
22 Pri Boom
Up coil
11 Shorted
to
supply
voltage
TCON detected that
C1PBU circuit is
shorted to 12 V.
Boom Up function will
not operate. Boom
Down will also not
operate if short is to
12 V.
* With a voltmeter, measure Y22.
Proper resistance should be between
5 - 60 ohms. Replace Y22 if
resistance is outside of those values.
* Verify wiring for C1PBU (RD, TCON
J4-10) and check for open or short
circuits.
23 Pri Boom
Down Coil
11 Shorted
to
supply
voltage
TCON detected that
C2PBD circuit is
shorted to 12 V or
GND.
Boom Up and Down
functions will not
operate.
* With a voltmeter, measure Y21.
Proper resistance should be between
5 - 60 ohms. Replace Y21 if
resistance is outside of those values.
* Verify wiring for C2PBD (RD/BK,
TCON J4-9) and check for open or
short circuits.
* Verify resistance between Recovery
Module pins J37-2 and J37-11 is zero
ohms.
