The top waveform is from the high side (feed side) of the #1 and #4 injectors, while the middle waveform is from the low side (ground side) of the #1 injector and the bottom waveform is from the low side of the #4 injector.
Inspection1.Turn the ignition switch OFF.2.Disconnect the injector connector.3.Measure resistance between the injector terminals 1 and 2.4.Check that the resistance is within the specification.
Removal1.Remove the front bumper.(Refer to Body - "Front Bumper")2.Disconnect the smart cruise control unit connector (A).3.Remove the smart cruise control nuit assembly (B) from thevehicle after loosening mounting bolts.Installation1.Install in the reverse order of removal.
Removal1.Disconnect the negative (-) battery terminal.2.Remove the rear bumper.(Refer to Body - "Rear Bumper")3.Remove the rear corner radar unit (A) after loosening the mounting nuts. • Take care not to separate the bracket from rear bumper when removing the rear corner radar sensor.
