Pin Voltage Tests

NOTE: In the following pin voltage tables, the letter "L" under wiring color represents the color Blue.

Access ECM. See ELECTRONIC CONTROL MODULE under REMOVAL & INSTALLATION. Turn ignition on. Using voltmeter, measure voltage at ECM. Check voltage between selected terminal and terminal E1 (ground). Voltage should be as specified in pin voltage tables. See Fig 1-Fig 6 .
