The ECU isn,t behind the passengers side kick panel ( passengers left foot ), i need your help

Should be inside of the passenger compartment in the lower right foot well behind the kick panel.

The engine computer (PCM/ECU) is located behind the passenger side kick panel. The pictures above should help. Hope it does.....

it is usually under the dash on driver side, maybe behind kick panel. Sometimes on passenger side but not ofiten.

the kick panel is next to your left foot (driver side) or next to your right foot (passenger side)-goes fron the floor to the bottom of the dash.

Try Looking on the inside of the car behind the front side foot/kick panels. (located at the foot sections/spaces in the front of the car on either the passenger or diver sides. (i.e. Behind the panels on the inside of car, close to the floor, behind the panels on the sides where you or the passengers feet go.)
Found mine there.
G'luck mate, :)

on the drivers side sit in the seat and with your left foot kick to the left that wall / area under the dash from the door, to the floor, to the firewall is referred to as the kick panel. revers using the right foot for the passengers side.

the cutoff switch is located behind the passenger foot well kick panel there is a hole to access the button u push down to reset the switch

I just changed mine, it's up under the dash on the driver's side above the fuse panel

dont know for sure but all nissans ive worked on are behind the passengers side kick panel ( passengers left foot )

If you are talking about the Theft deterrent ECU it is behind dash above left kick panel.( near drivers left foot) all other moduels are behind glove box, behind passenger side right kick panel or under center consel below stereo and next to storage box in front of E brake handle.
