if an "A" is displayed on the dash this indicates a "Head Capacitor" Failure.
The Head Capacitor ensures that a steady voltage is maintained to the positive headsink and that large voltage spikes are filtered out. The logics monitors this at P2-2.
Performance of the truck will be reduced when this error is active.
