1985 SL 380 ABS trouble

[Wdmh306]

Hi All,

Glad to be here. Needing some guidance.

I have recently purchased a 1985 SL 380. The abs light was/is on. I have tested the wheel sensors. 780 ohms at the rear, 1260 on the passenger side, 1270 on the driver. All within specs. I have also changed the ovp relay even though there was no high idle apparent. Where do I go next? The relays on the abs pump??

Thank you

Bill

Did you scan for codes? What codes did you get?

Scan for codes? Please tell us about how to do that on an '85 R107.

This system works blind? Ick. There has to be some way to determine what is at fault.

Another test for wheel speed sensors is to hook up a AC volt meter and spin the wheel. If the gap between the sensor and reluctor is too great, the voltage produced will be low.

Cycle the ABS system several times by braking on a loose or gravel surface. Does the ABS work? Does exercise extinguish the ABS warning light?
