hi all i have been having major trobules since fitting my parrele fuel mod and also my 440's
My abs light is now on and myecu is showing a code 53 ? but which one ?
as scoobypedia lists 9 of them

any ideas of the above how to you find a fult on a classic abs system
also how to you reset and air bag light ?

All of the 53 errors are related to the factory fit transponder-based immobiliser. There are eight possible options on an Impreza and the only way to find out for certain which one it is would be to connect the car to a Select Monitor (or 100% compatible emulator).

Incidentally, if you've connected the black plugs and found the 53 code stored, if you don't know otherwise it may well be an historic code that's been hanging around in its memory since who knows how long. You'll know if it's actually been triggered recently as the symptom you'll notice will be that the engine will turn over, fire and then immediately stall, with either or both of the Check Engine or the little key symbols flashing afterwards.

Either a process of elimination or, again, diagnose it with a Select Monitor. Did the warning light come on immediately after your fuel mods? If so the obvious thing to look at would be the possibility of you disturbing something in the pump area. Other common cause, especially on an older car, is a wheel speed sensor failure.

Fix whatever's caused it to illuminate.

 

many thanks for replying the code might be a 43 so i just reset ecu again ,

air bag was when i removed my steering wheel and tryed to fit an aftermarket one then decided to fit oe again in the space of 30-45 mins batt was off also ?

just removed all wheels and cleaned up abs pick up's when you turn ign on the light come on then turn off again but mine seems to try to go out but then comes on again i did remove the washer bottle also this might of done it ahhhhhhhh seems to be no end

i though when i did a shrp stop after the inj fitting might of done somthing as it behaved a bit funny any other ideas?

 

right just checked out the two front abs sens and got 1.13k restance on both didnt do back one's couldnt see them had a look around pump side nowt showing wrong please loosing my marbles now

 

any 1 ?

 

right heres a follow up
checks all abs sensors all showing 1.13k res
checks all fuses all ok
checked all wire by pump all ok
found yellow plug and the two fly leads for diagnosis, tryed to get code but abs light wont flash i put it into the bottom right most space 6


any ideas as i am out of ideas

 

When you checked the impedance of the wheel sensors, did you check that the resistance fluctuated when the wheel was rotated?

Also as far as Deepy's instructions to query the ABS ECU, make sure you're counting pin 6 correctly!

 

hi splitpin i didnt spin the wheel ,
on the link below look at the first box with the wiring discription i have wires in the following
