Electronic Component Handling

STATIC DISCHARGE
^ 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.
^ Never touch the ECM connector pins, integrated circuit connector pins, or soldered components on the ECM circuit board.

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

CONTROL UNIT DAMAGE
^ Do not try to disassemble the Control Module.
^ Before performing electrical welding (for instance, spot welding), disconnect the battery, climate control, injection, cruise control, ECM and radio.
^ If temperatures may exceed 176°F (80°C), (example: infra-red spray booth), remove all ECUs.
^ Avoid getting water on any of the Fuel and Engine Control System Components.
^ Never apply battery power to a component unless directed to do so in a test procedure.
^ Only use test equipment that is of proper specifications for the tests involved.Refer to Tools and Equipment for test equipment specifications.
