Pin Voltage Tests
NOTE:
Unless stated otherwise in testing procedures, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Voltage readings may vary slightly due to battery condition or charging rate.
NOTE:
On G20, voltage specifications are measured between each terminal and ECM terminal No. 48 (ECM ground).
NOTE:
On Q45, voltage specifications are measured between each terminal and ECM terminal No. 128 (ECM ground).
