Electronic Component Handling

STATIC DISCHARGE
^ Discharge 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 PCM connector pins, integrated circuit connector pins, or soldered components on PCM circuit board.

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

CONTROL UNIT DAMAGE
^ Do not try to disassemble PCM.
^ Before performing electrical welding (example: spot welding), disconnect battery, climate control, injection, cruise control, PCM and radio.
^ If temperatures may exceed 176°F (80°C), (example: infra-red spray booth), remove PCM and other electronic control units.
^ Avoid getting water on fuel and engine control system components.
^ Never apply battery power to a component unless directed to do so in a test procedure.
