Although the Secondary Quick Check is fully functional on Distributor Ignition (DI) systems, some
applications filter the ignition signal as it passes through the distributor. This distorts the signal
at the individual spark plug wires. For this reason, Bosch recommends using the Secondary
Ignition Mode on Distributor Ignition (DI) vehicles.
