Chassis Control Unit
(Crossfire/F-Series/
M-Series Models)
The Chassis Control Icon 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 illumintated or
it illuminates while the engine is running, the CCU is
receiving input that is outside of its established parameters.
Diagnostic Codes/
Chassis Control Unit
(Crossfire/F-Series/
M-Series Models)
These diagnostic codes are flashed by the wrench icon
light incorporated within the speedometer/tachometer.
Refer to the following chart for diagnostic code
sequences.
NOTE: On these double-digit codes (3-1, 3-2, 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.
