This diagnostic code is generated when the powertrain ECM identifies

starting is disabled.
Above Normal
Operational Range
This diagnostic code is generated when the diagnostic circuit of the
0168 01
Electrical System
powertrain ECM identifies a system voltage that is below 18.0 DCV.
Voltage Data Valid but
The system voltage remains low for an extended time after the engine

battery and the powertrain ECM. There is an open circuit on one or
more wires providing ground to the powertrain ECM. One set of
batteries is disconnected with the key in the ON position. Also, the
engine must not be running. When this code is generated, the functions
of the transmission are disabled until the voltage is above 18.0 DCV
and the direction switch is placed in neutral.
This diagnostic code is generated when the powertrain ECM reads the

and CAN data link. The engine must be running in order for the
powertrain ECM to show this diagnostic code. When this code is
generated, transmission shift points will be affected and calibrations
will be disabled.
This diagnostic code is associated with the rocker switch for ride

This FMI 03 indicates that the powertrain ECM has determined that
both contacts are open.
