Engine Controls - Pin Voltage Charts: Introduction
NOTE:
Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Carefully backprobe PCM harness connector using Backprobe Set (07SAZ-001000A
) to avoid damage. Voltage readings may vary slightly due to battery condition or charging rate.
NOTE:
PCM may also be referred to as ECM.
