Low
Master TEC
This fault is reported
when the TEC-5002
detects that the 12 Vdc
charging system
(alternator) is
generating less than
8.8 Vdc.
1) Check the alternator drive belt.
2) Test the alternator.
3) Test the wiring harness.

Ignition switch
malfunction
Master TEC
This fault is reported
when the TEC-5002
detects the
key START
input is active but
the key RUN input is
off.
The ignition switch has 2 output
pins. Only 1 should be active at
any given time.
1) Test the ignition switch using
the InfoCenter.
2) Test the ignition switch
manually.
3) Test the ignition switch circuit
wiring.
15
Engine Speed
Switch Broken
Master TEC
This fault is reported
when the TEC-5002
detects an engine
speed increase signal
and an engine speed
decrease signal at the
same time.
The engine speed switch may
be shorted internally, or the
outputs of the engine speed
switch may be shorted together
in the seat wire harness.
1) Test the engine speed switch.
2) Test the engine speed switch
wiring.
16
12 Vdc Alternator
Malfunction
Master TEC
This fault is reported
when the alternator is
faulty.
1) Test the alternator.
2) Test the wiring harness.
17
Reel Enable Out is
Overcurrent
Master TEC
This fault is reported
when the measured
reel enable output of
the TEC is beyond the
upper limits.
The reel engage/disengage
switch is also referred to as the
cutting unit enable/disable
switch.
1) Test the 48V logic relay enable.
2) Test the 48V logic relay function.
3) Test the harness for a short.
19
Engine Coolant
Temperature Out of
Range
Master TEC
This fault is reported
when the engine
coolant temperature
sensor is either open
or shorted.
The temperature sensor is also
called a temperature sender.
1) Test the temperature sensor
wiring.
2) Replace the temperature
sensor.
