2000 Powertrain Control/Emissions Diagnosis Manual, need lookup

Hi,

Trying to determine if there is any useful Smart Charge System diagnosis steps in this manual. In particular pictures of the control and feedback PWM (Pulse Width Modulated) wave forms.

I've heard they basically tell you to use the STAR tester.

If someone could check this for me, I could determine if I should buy the manual or not.

Thanks in advance,
Tom
