1. An apparatus for evaluating performance of an integrated coil on plug (CoP) assembly comprising:
- a controller configured to;
transmit a control signal to activate the CoP assembly;
receive an indirect signal having a first characteristic associated with a low frequency (LF) component between 50 to 250 KHz from the CoP assembly responsive to the control signal; and
compare the first characteristic to first predetermined data to evaluate the performance of the CoP assembly.

Abstract
In at least one embodiment, an apparatus for evaluating performance of an integrated coil on plug (CoP) assembly is provided. The apparatus comprises a controller. The controller is configured to transmit a control signal to activate the CoP assembly. The controller is further configured to receive an indirect signal including a low frequency (LF) component from the CoP assembly responsive to the control signal. The controller is further configured to compare the LF component to predetermined data to evaluate the performance of the CoP assembly.

9. A method for evaluating performance of an integrated coil on plug (CoP) assembly in an apparatus comprising:
-
transmitting a control signal to activate the CoP assembly; receiving an indirect signal having a first characteristic associated with a high frequency (HF) component between 2 to 30 MHz from the CoP assembly responsive to the control signal; and comparing the first characteristic to first predetermined data to evaluate the performance of the CoP assembly. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for evaluating the performance of an integrated coil on plug (CoP) ignition assembly in a vehicle, the method comprising:
-
controlling a switch positioned within the integrated CoP assembly to close for a fixed period of time, followed by controlling the switch to open to initiate a firing of a spark plug coupled to the CoP ignition assembly; collecting an indirect signal associated with the firing of the spark plug;
the indirect signal having a first characteristic associated with a low frequency (LF) component and at least one second characteristic associated with a high frequency (HF) component;comparing the first characteristic and the at least one second characteristic to first predetermined data and second predetermined data respectively; determining a defect based on the comparison; and setting a fault if a defect is determined. - View Dependent Claims (18, 19, 20)
