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 ECU connector pins, integrated circuit connector pins, or soldered components on the ECU 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 (for instance, spot welding), disconnect the battery, climate control, injection, cruise control, ECU and radio.
- If temperatures may exceed 176°F (80°C), (example: infra-red spray booth), remove all ECU's.
- 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.
