System Response:
0268-02 Programmed
Parameter Fault Erratic,
The MSD will display a list of
Intermittent, or Incorrect
condition(s) on Active Diagnos-
tics screen that must be
resolved.
A warning will display on instru-
ment panel.
Possible Performance Effect:
ECM may limit engine to low idle.
Engine performance and emissions
are affected.
1. Connect MSD (WP 0006). Select
Engine ECM C6.6 120M and
verify 0268-02 is active.
