Electronic Component Handling


STATIC DISCHARGE

1. Discharge any static electrical charges before handling electronic parts by touching ground or maintaining a ground connection to a bare skin area like the wrist.
2. Never touch the Electronic Control Assembly (ECA) connector pins, integrated circuit connector pins, or soldered components on the ECA circuit board.

TESTING

1. When measuring voltage at the ECA harness connector, disconnect harness connector with the ignition OFF, then turn ignition "ON" as necessary.
2. To prevent deforming ECA harness connectors, do not probe terminals directly. Instead, insert a pin from the harness side and perform measurements through pin.

ELECTRONIC CONTROL UNIT DAMAGE

1. Do not try to disassemble any ECA.
2. Before performing electrical welding (for instance, spot welding), disconnect the battery, climate control, cruise control, ECA and radio.
3. If temperatures may exceed 176°F (80°C), (example: infra-red spray booth), remove all ECA's.
4. Avoid getting water on any of the Fuel and Electronic Control System Components.
5. Never apply battery power to a component unless directed to do so in a test procedure.
