Circuit Description
Immobilizer is a device disabling vehicle ignition unless a specific key is used and designed to help prevent vehicle
theft.
Immobilizer is comprised of two devices, a key with encoded transponder and ECM with the same encoding of the
transponder. When a key is inserted into the hole to start vehicle and turned to ON, the ECM reads and decodes the
transponder code and, if the same, starts the engine, it is called immobilizer. It means immobilizer system disables
starting by stopping fuel supply if the code in the transponder does not match the code stored in ECM each other.

avoid fuel spillage and the risk of personal injury or
fire, it is necessary to relieve the fuel system pres-
sure before disconnecting the fuel lines.
1. Relieve the fuel system pressure. Refer to “Discharg-
ing the Pressure in Fuel System” in this section.
2. Disconnect the negative battery cable.
3. Put aside the floor carpet to remove the fuel pump ac-
cess cover.
4. Remove the fuel pump access cover.
5. Remove the fuel pump wiring connectors.
