ABS relay questions
my my abs relay is on the fritz. I pulled it out. I don't see any obvious failure, which pins activate the relay?

Should be positive 31 and ground 15 correct?

30 Line from battery positive terminal
31 Return wire from battery Negative or ground (direct)
15 Switched positive after battery (ignition-switch output)
87 Input
this is Bosch own designation of numbers

I thought it looks like 31 and 15 go through the coil windings on the diagram.

so if so positive on 15 and negative on 31 should activate the relay?

So when you turn ignition on the relay will be activated and pull and give power to 87 that are given signal /12Volt to xxx
Like the #30 + gets connected to #87 to deliver +
