GRB = JDM 2.0L Hatch
GRF = UK/Europe 2.5L Hatch

Fuse #7 in engine bay Main fuse box or in driving compartment fuse box??

Main fuse box fuse #7 - Headlights high beam relay output

Driving Compartment fuse box fuse #7 - circuits FB-17 and FB-18

With key ignition


With push button start

thanks for the guidance but the trouble of guidance not exist , the car start and work fine, i have only battery draw 0.27A on this circuit, maybe some grounds is possible?

Don Clark

Taken from the UK/European workshop manual, so hopefully similar to JDM




Ground GB-4 (Centre Dashboard area) is also linked to Ground GB-6 (fusebox area)

stupid question ... i dont understand where is the collation cm .... need to remove the dashboard right ?

Don Clark

According to the Bulkhead wiring diagram the modules sit in a group tucked up high on the bulkhead.
I would imagine you can access via the drivers footwell and the dash end panel once you have removed the dashboard drivers side lower panel.

AFAIK the ID code box sits behind/in line with the start button above and behind the fuse box.

UK/EU reference - I believe "MAIN ECU" is collation cm


JDM equivalent
