Check Engine Light
(Crossfire/F-Series/
M-Series Models)
The Check Engine Light is controlled by the ECU and
may illuminate for a number of reasons. The light
should illuminate each time the key is turned to RUN
or START, and it should go out when the engine starts.
If the light stays illuminated or it illuminates while the
engine is running, the ECU is receiving input that is
outside of its established parameters.
Diagnostic Codes/
Check Engine
(Crossfire/F-Series/
M-Series Models)
These diagnostic codes are flashed by the check engine
light incorporated within the speedometer/tachometer.
Refer to the following chart for diagnostic code
sequences.
NOTE: On single-digit codes (2, 4, etc.), the number
indicated will flash in an uninterrupted
sequence. On double-digit codes (1-2, 1-6, etc.), the
first number indicated will flash in an uninterrupted
sequence, there will be a short pause, and the second
number indicated will flash in an uninterrupted
sequence.
If the coolant temperature is at or above 80° C (176°
F), the coolant temperature light will flash a warning
(alert). If the coolant temperature is at or above 93° C
(200° F), the coolant temperature light will cease flashing
and will remain constantly illuminated.
