STATIC DISCHARGE
1. 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.
2. Never touch the Engine Control Module (ECM) connector pins, integrated circuit connector pins, or soldered components on the Engine Control Module (ECM) circuit board.
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 UNIT DAMAGE
1. Do not try to disassemble the control unit.
2. Before performing electrical welding (for instance, spot welding), disconnect the battery, climate control, injection, cruise control, ECM and radio.
3. If temperatures may exceed 80°C (176°F), (example: infra-red spray booth), remove all sensitive electronic devices.
4. Avoid getting water on any of the Fuel and Engine Control System Components.
5. Never apply battery power to a component unless directed to do so in a test procedure.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
