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
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.
187 TCON Bank
power
13 Not
detected
Power plug not
connected or
loose.
Internal TCON
component failure.
TCON outputs will
not turn on.
* Check J1, Bank Power, on TCON is
making a good connection.
* Verify pin 1 is grounded
* Verify pins 2, 3, 4 are 12V
* Replace TCON
188 PCON Bank
power
13 Not
detected
Power plug not
connected or
loose.
Internal TCON
component failure.
PCON outputs will
not turn on.
* Check J11, Bank Power, on PCON
is making a good connection.
* Verify pin 1 is grounded
* Verify pins 3, 4 are 12V
* Replace PCON
