Electronic Component Handling

TESTING
1. When measuring voltage at the control unit harness connector disconnect harness connector with the ignition OFF then turn ignition ON as necessary.
2. 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 MODULE PRECAUTIONS
1. Do not try to disassemble a control module.
2. Before performing electrical welding disconnect the battery, climate control, injection, cruise control, engine control module, transmission control module and radio.
3. If temperatures may exceed 80°C (176°F) remove all control units.
4. Avoid getting water on any fuel and engine control system components.
5. Never apply battery power to a component unless directed to do so in a test procedure.
