Part No. 1285307GT
ID Component ID
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
Mismatched 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.
