Fuel pump shut off system
To minimize the risk of fuel leakage when the engine stalls or when an airbag inflates upon collision, the fuel pump shut off system stops the supply of fuel to the engine. Follow the procedure below to restart the engine after the system is activated. Vehicles without a smart key system Tu ...

Tc and cg terminal circuit
Description Dtc output mode is set by connecting terminals tc and cg of the dlc3. The dtcs are displayed by blinking the srs warning light. Hint: Make sure that dtc b1281 has not been output. If dtc b1281 has been output, refer to the multiplex communication system. When each warning ...
