Hi there new to wrx and the site . It’s a 2003 blobeye . My door light on dash is flickering, also when going over bumps . I have replaced the door sensors but it’s is still happening and can’t set my alarm it’s a standered one alarm. . Could it be a short in the wiring somewhere. Or I have read somewhere the integrated unit . Hope to get sort for weekend thanks Steve

Boot sensor?

Steves1234

I have looked at boot sensor I think I am looking at the right bit The black part next the lacth. The boot light dose what it’s meant do open it’s on close it off . Have looked tho rear seat too it’s not on then it’s shut .

Unless it's JDM it won't have a Body Integrated unit.
If UK unlikely to be boot light switch as it doesn't appear to link into the dash light.

Each door switch has two wires to it one being an earth (black).
Make sure when the switch is removed the other wire on each doesn't make to earth.

What is the integrated unit I have a 03 jdm and has the open door sort of semi lit up and have changed all 4 door sensors

Don Clark

The body integrated unit used in JDM and US cars, and which arrived with the Hatch here in the UK and Europe "integrates" a number of the electrical functions of the cars electrical system through a single "box of tricks".

For example
Headlight beam levelling

Rear fog light


Keyless access

Interior lamps


BIU has been around in the UK Legacy from MY04.

MY02 US Impreza Keyless entry and room lights

Thanks for reply. Have had a look under dash and it has a integrated unit so must be Jdm then . I had lose bolts on on boot latch done them up it’s gone out for now . Could be as simple as that . Alarm is working again now been set for 20mins

So drove off drive way and it’s back on again

Don Clark

You found one of these lurking under the dash




Easiest way to tell if JDM or UK is the VIN

JDM format GDA-xxxxxx
UK format JF1GDAKD3#Gxxxxxx

where # = Year character and xxxxxx =serial number

Steves1234

Yes found one off them . I don’t know if it can affect the door dash light ? . Would it be a bad wire somewhere maybe . As can strip it down on weekend

Don Clark

Depends how the far your JDM's wiring is integrated into the BIU circuitry. For the Hatch the door open warning light in the combination meter is fully integrated into the BIU, where as in the early US model it's not.

Somebody previously posted that a loose door lock mechanism or badly adjusted striker plate could leave a door switch teetering between open or closed contact.
You found a loose boot lock, maybe check the rest of the door lock screws are tight.

Ok thanks I will have a look . Let you know .
