Engine Stop Light
The engine stop light is located at the top of the front console
in the carrier cab. It is a red indicator light that illuminates to
signify a serious engine problem that requires the vehicle
and the engine to be stopped as soon as safely possible.
In addition to alerting the operator of system faults, the
engine stop light, along with the engine warning light, is used
in the diagnostic operation of the engine control system.
NOTE: When not using the diagnostic system, turn the
engine diagnostic switch to the OFF position.
The diagnostic mode begins when the ignition and engine
diagnostic switches are on and the engine is not running.
The amber light flashes at the beginning of a fault code
sequence, the red light flashes the three- or four-digit code
for the active fault and the amber light flashes again to
separate the previous red light sequence from the next one.
Each code will be flashed once before moving to the next
code. When all codes have been flashed, the sequence will
begin again. If no codes are present, both the warning and
stop lights will remain on.
Engine Warning Light
The engine warning light is located at the top of the front
console in the carrier cab. It is an amber indicator light that is
a part of the engine’s electronic control system and when
illuminated, gives the operator a signal that there is an
engine problem which must be corrected.
In addition to alerting the operator of system faults, the
engine warning light, along with the engine stop light, is used
in the diagnostic operation of the engine control system.
NOTE: When not using the diagnostic system, turn the
engine diagnostic switch to the OFF position.
The diagnostic mode begins when the ignition and engine
diagnostic switches are on and the engine is not running.
The amber light flashes at the beginning of a fault code
sequence, the red light flashes the three- or four-digit code
for the active fault and the amber light flashes again to
separate the previous red light sequence from the next one.
Each code will be flashed once before moving to the next
code. When all codes have been flashed, the sequence will
begin again. If no codes are present, both the engine
warning and engine stop lights will remain on.
Fault Code Flashing Sequence
The amber engine warning light flashes at the beginning of a
fault code sequence. There will be a short 1- or 2-second
pause after which the number of the recorded fault code will
flash in the red engine stop light. To interpret the flash code,
count the first sequence of red flashes for the first digit and
after a two second delay, count the second sequence of red
flashes for the second digit. when the number has finished
flashing in red, the amber engine warning light flashes again.
The lamps flash each fault code one time before advancing
to the next code. To skip to the next fault code, move the
engine diagnostics idle switch in either position (+/-) to see
other fault codes. If only one active fault is recorded, the
control system will continuously display the same fault code
when pressing the engine diagnostics idle switch. Refer to
the engine manufacturers service manual for explanation
and correction of the fault codes.
Regen Needed/Inhibit Indicator
This dual lamp indicator is located on the right side of the
front console in the carrier cab.The upper lamp is used to
indicate when the first level of exhaust regeneration is
needed. The Inhibit Indicator is illuminated when Regen
Inhibit Switch has been activated.
High Exhaust Temp Indicator
The high exhaust temp indicator lights when an active
exhaust regeneration has been initiated and the exhaust
temperatures will be elevated above normal levels for the
vehicle operating conditions This can occur while driving or
during a manually initiated “stationary regeneration”.
WARNING
While regenerating, ensure the exhaust is not aimed at
any surface or material that will melt, burn, or explode.
