Toyota Corolla (E120): Electronic control
- Removal and installation of battery terminal
- before performing electrical work, disconnect the battery negative (–) terminal cable beforehand so as to prevent burnt–out damage by short.
- When disconnecting and installing the terminal cable, turn the ignition switch and lighting switch off, and loosen the terminal nut completely. Perform these operations without twisting or prying the terminal.
- When the battery terminal is removed, all the memories
of the clock, radio, dtcs, etc. Will be erased.
So before removing it, check them and note them down.

- 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 destroyed 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 floor, they should be replaced and not be reused.
- 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 continuity at the wire connector, insert the tester probe carefully to prevent terminals from bending.
