ID Component ID Name
Cause
Effect
Solution
160 LF Steer (L
or R) Coil
11 Shorted
to supply
voltage
TCON detected
that C37STL circuit
is shorted to 12 V
or GND.
Steer Left function
will not operate.
* With a voltmeter, measure Y3.
Proper resistance should be
between 5 - 60 ohms. Replace Y3 if
resistance is outside of those values.
* Verify wiring for C37STL (BL/BK,
TCON J4-11) and check for open or
short circuits.
161 RF Steer (L
or R) Coil
11 Shorted
to supply
voltage
TCON detected
that C36STR circuit
is shorted to 12 V
or GND.
Steer Right function
will not operate.
* With a voltmeter, measure Y4.
Proper resistance should be
between 5 - 60 ohms. Replace Y4 if
resistance is outside of those values.
* Verify wiring for C36STR (BL,
TCON J4-12) and check for open or
short circuits.
185 ESTOP
Source
11 Shorted
to supply
voltage
TCON detected
that ESTOP 1 is at
12 V but ESTOP 3
is at 0 V.
ESTOP circuit
cannot complete,
preventing machine
functions.
* Using a voltmeter and with the
system turned OFF, check the
resistance between TCON J5 pins 9
and 10. Replace TCON if resistance
is more than 5 ohms.
* Check P79PWR (BK, TCON J5-9)
and P23PWR (RD, TCON J5-10) for
open or short circuits.
186 ESTOP
Return
11 Shorted
to supply
voltage
Mistmatched
signals detected on
ESTOP Return
circuits. Either:
* PCON ESTOP 2
and ESTOP 4 do
not match, or
* TCON ESTOP 2
and ESTOP 4 do
not match.
ESTOP circuit
cannot complete,
preventing machine
functions.
* Inspect PCON J15 pins 11 and 12
for open or short circuits. Using a
voltmeter, set to diode test mode and
make sure the diode tests ok with the
anode at pin 12 and cathode at pin
11. If test fails, replace the PCON.
* Inspect TCON J5 pins 11 and 12 for
open or short circuits. Using a
voltmeter, set to diode test mode and
make sure the diode tests ok with the
anode at pin 12 and cathode at pin
11. If test fails, replace the PCON.
* Check P23RET (BK) for shorts to
ground or power.
