Idle validation signal at pin 26 of
the OEM harness indicates the
throttle is at the idle position
when the throttle position signal
at pin 30 of the OEM harness
indicates the throttle is not at the
091
idle position ... OR ... idle
13
validation signal at pin 26 of the
OEM harness indicates the
throttle is not at the idle position
when the throttle position signal
at pin 30 of the OEM harness
indicates the throttle is at the idle
position.
Boost pressure signal indicates
boost pressure is high when
102
other engine parameters (i.e.,
2
speed and load) indicate boost
pressure should be low.
Supply voltage to the ECM fell
below 6.0 VDC for a fraction of a
627
second ... OR ... the ECM was
2
not allowed to power down
correctly (retain battery voltage
for 30 seconds after key OFF).
Voltage detected at ECM power
168
supply pins 38, 39, and 40 of the
1
engine harness indicates ECM
supply voltage fell below 6 VDC.
Voltage detected at ECM power
supply pins 38, 39, and 40 of the
168
engine harness indicates the
0
ECM supply voltage is above the
maximum system voltage level.
Low voltage detected at throttle
620
position sensor +5 VDC supply
1
pin 29 of the OEM harness.
Low voltage detected at OEM
620
harness sensor +5 VDC supply
1
pin 10 of the OEM harness.
Intake manifold air temperature
signal indicates intake manifold
105
air temperature is above the
0
minimum engine protection
threshold.
Auxiliary device speed signal on
191
pins 8 and 18 of the OEM
1
harness is out of range of the
ECM threshold.
Efectos
Engine will only idle.
Possible overfueling during
acceleration. Increase in black
smoke.
Possible no noticeable performance
effects OR engine dying OR hard
starting.
Fault information, trip information,
and maintenance monitor data may
be inaccurate.
Engine will die or run rough.
None on performance.
Engine idles when idle validation
switch indicates idle and ramps up
to a default set speed when idle
validation switch indicates off-idle.
Sensors connected to this +5 VDC
supply (i.e., remote throttle position
sensor) will not function.
Power derate and possible engine
shutdown if engine protection
shutdown feature is enabled.
Lose ability to control the speed of
the auxiliary device.
