System Response:
Drive Current Above Normal A warning will display on instrument
panel. ECM will log diagnostic code.
Possible Performance Effect:
Engine ECM will log a diagnos-
tic code, and a warning will
appear on instrument panel
once diagnostic code has been
active for 30 seconds.
The engine ECM will derate
engine while diagnostic code is
active. After derate has been
activated, the Engine Power
Derate parameter on the MSD
will display 100%.

System Response:
ECM will log diagnostic code. A warn-
