[Mk2] [NA] Rev4 - ABS warning light - how to read codes please

[frazman]

Hi folks, Haven't drivent the MR2 for a while and now the ABS warning light is illuminated on the dash. Have taken to 2 local garages for a plug in but the code readers can't communicate with the car? It is a UK rev4 and i found an online guide for reading codes using the wire pin (i'm unable to post a link to the post) however the guide is for rev2 and when i follwed the gudielines the P/S warning would flash codes not the ABS which remained constant. I noticed my abs warning light was in a different location to the one on the rev2 also.

So does anyone have a guide on how to read the code correctly on the rev4 model pls.

I imagine it's a dodgy sensors perhaps as the brakes feel fine.

Thanks for any help in advance.

Regards Fraz

bridge Tc and E1

this will bring up error codes for ABS

heres the error codes

thanks thats what i have tried - so it makes no difference reading codes for the different rev of mr2?

it states at the bottom of the code list always on = ecu. Does the abs have a stand alone ecu? regards Fraz

are you sure you bridge Tc + E1 and not the usual TE1 + E1

Yes the ABS has its own ECU

All codes are the same no matter what REV you have

You more than likely have a duff sensor but would need to know the code for which one or the ABS rings have rusted or covered in gunk

Thanks again alan - yes i did tc to e1 as per the stephenmanson online guide but i just get a flashing p/s warning and the abs light stays constant so i assume the abs ecu is going to be the logical first port of call?

well here's where the ECU is located under the dash but under your passenger side not as in pic as that\s for left hand drive
