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 176°F (80°C) 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.
