Electronic Component Handling

STATIC DISCHARGE
^ Before handling electronic parts discharge static charges by touching ground or maintaining a ground connection to a bare skin area.
^ Never touch control unit connector pins, integrated circuit connector pins, or soldered components on the control unit circuit board.

TESTING
^ When measuring voltage at the control unit harness connector disconnect harness connector with the ignition OFF then turn ignition ON as necessary.
^ To prevent deforming control unit 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 unit.
^ Before performing electrical welding disconnect the battery, climate control, injection, cruise control, control unit, and radio.
^ If temperatures may exceed 80°C (176°F) remove all control units.
^ Avoid getting water on any fuel and engine control system components.
^ Never apply battery power to a component unless directed to do so in a test procedure.
