1. Which of the following is an advantage of a COP ignition system?
A. There is less potential for the secondary circuit to induce a voltage in a nearby circuit.
B. It is easier to connect a secondary ignition oscilloscope to the system for diagnosis.
C. The ignition coils used in this system no longer contain primary windings.
D. This system uses a pickup in a distributor, thereby allowing base timing to be adjusted.

1. Which level of information, as described in this chapter, is required for the PCM and/or ignition module to fire the correct ignition coil in a waste spark ignition system?
A. First level; identifying “a
pair
of cylinders’ pistons are approaching TDC”
B. Second level; identifying
“which pair
of cylinders’ pistons are approaching TDC”
C. Third level; identifying
“which cylinder
of the piston pair approaching TDC is on the compression stroke”
D. None of the preceding answers provides enough information for the correct ignition coil to be fired.
