JA11 - Check CKP Amplitude at ICM

- Key Off.

- DVOM on 40 volt AC scale.

- Crank engine and measure voltage between J35 (CKP+ I) and J48 (CKP- I) at breakout box.

- Is settled AC voltage reading greater than 0.4 volts?

YES -- Go to Pinpoint Test Step JC1. JC1 - Check For Spark During Crank

NO -- Amplitude fault. Go to JA12. JA12 - Check CKP Amplitude at ICM - Amplitude Fault
