Intake Air Heater Number 1
Circuit - Shorted Low. Low
voltage detected at the Intake
Air Heater Signal Circuit.
The intake air heaters may be
ON or OFF all of the time.
697
{3}
PWM Output Device Driver
(Transmission Shift
Modulation) - Shorted Low.
No voltage is detected when
voltage is commanded.
The engine and transmission
interface will possibly not
function properly.

{15}
EGR Temperature - Data Valid
but Above Normal Operating
Range - Least Severe Level.
Engine power derate.
412
{16}
EGR Temperature - Data Valid
but Above Normal Operating
Range - Moderately Severe
Level.
Engine power derate.
110
{15}
Engine Coolant Temperature
High - Warning. Engine
temperature signal indicates
engine coolant temperature is
above engine protection
warning limit.
Power derate and possible
engine shutdown if engine
protection shutdown feature is
enabled.
105
{15}
Intake Manifold Air
Temperature High - Warning.
Intake manifold air
temperature signal indicates
intake manifold air
temperature is above the
engine protection warning
limit.
Engine power derate.
102
{2}
Intake Manifold Pressure -
Data Incorrect. The ECM has
detected an intake manifold
pressure signal that is too high
or low for current engine
operating conditions.
Engine power derate.
