Precautions on Operating Vehicle’s ECU 
  Do not disconnect battery or any wiring cables in the vehicle when the ignition 
switch is on, as this could avoid damage to the sensors or the ECU. 
  Do  not  place  any  magnetic  objects  near  the  ECU.  Disconnect  the  power 
supply to the ECU before performing any welding operations on the vehicle. 
  Use  extreme  caution  when  performing  any  operations  near  the  ECU  or 
sensors. Ground yourself when you disassemble PROM, otherwise ECU and 
sensors can be damaged by static electricity. 
  When reconnecting the ECU harness connector, be sure it is attached firmly, 
otherwise electronic elements, such as ICs inside the ECU, can be damaged.
