Handling Of Electronic Parts
- Do not open the cover or case of the ECU unless absolutely necessary. If the IC terminals are touched, the IC may be rendered inoperative by static electricity.
- To disconnect electronic connectors, pull the connector itself, not the wires.

- Be careful not to drop electronic components, such as sensors or relays. If they are dropped on a hard surface, they should be replaced.
- When cleaning the engine with steam, protect the electronic components, air filter and emission-related components from water.
- Never use an impact wrench to remove or install temperature switches or temperature sensors.
- When checking the resistance of a wire connector, insert the tester probe carefully to prevent terminals from bending.
