abs light on

[peterllo]

1995 E34, M50 Auto with 205K

The ABS light came on some time ago, brakes are fine, fluid is fine. Other than going to the dealer for a scan any ideas?

The two rear tires were just changed yesterday, they were kind of bald, the light is still on.

many factors. different tires, abs pump fault , abs computer or relay fault , one or more of the 4 wheel sensors... have it scanned

on mine the cause was a charging problem (battery or alternator) the abs master is on the same circuit.

use obc test #9 to confirm you are getting at least 13V when running.

hey tim have you sorted out your charging issues?

not yet, i'm waiting for spring (it's still -14'c here) to do the alt/starter/bat+ cable swap.

i'm certain my problem is in there somewhere, i think either the alternator cable or the connector.

for now i just keep the obc on test9 and make sure i keep it above 13v all the time. it's rare that i can use the rear defrost which sucks but i can live with it.

thanks for the pics.

i replaced the batt/chassis/engine grounds too...

this looks like the old alternator pos wire- you had that replaced? to the connector at the starter?



sorry if i'm pointing out the obvious but the alternator D+ ring terminal/wire is busted in that photo... that wasn't it either?
i changed both ring terminals but not the whole wire yet... it's ready for a warm spring day...

[bmwrp8]

oops. i posted the old alt. pix. sorry. I had that wire replaced too alt to starter. charging is still bad when full load.I might end up getting an alt. again for the FOURTH time!
