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 PCM connector pins, integrated circuit connector pins, or soldered components on the PCM 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, PCM and radio.

- If temperatures may exceed 176°F (80°C), (example: infra-red spray booth), remove all control modules.

- 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.
