Pin Voltage Tests

NOTE: Instrument panel Electronic Control Unit (ECU) is located behind center of instrument panel and contains a 14-pin, 18-pin and 22-pin electrical connector. See Figure. When performing pin voltage tests, most wires are Sky Blue at the instrument panel ECU, but may change wire color in the wiring circuit to the specified component. See WIRING DIAGRAMS . Sky Blue wires are marked with a terminal number for wire identification. Ensure proper pins are used on instrument panel ECU when performing pin voltage tests. Ensure pin voltage values are within specification. See Fig 1-Fig 3 .
