I have an e36 318tds touring of 98 vintage and recently both abs light and asc light came on. They came on at start up and never went out,I hadn't seen a flicker from them beforehand.
I connected the car to a mates Launch system only to find that the abs module couldn't be read.
I have checked the fuses for the abs system and all seem ok, I have read on google that there are also two relays that control the abs system, but any pictures I seen have them in a spot where I have no relays. There is also no 'map' of relays on the fuse box lid.
Has anyone had any experience of these systems? I take it I should be able to read the module even if it is faulty and I should be looking for a faulty power supply to the module, hence the checking for relays.
I have found an online service manual for my car but can't seem to find a wiring diagram for the abs/asc system.
Any suggestions appreciated.
