ABS light on?

Hi,

I attached two pics. The first is the master cylinder (exploded view) The second shows the ABS pump, module and other components. See the pic and let me know the name of the component is.

Hi,

I don't have an exploded view of the modulator. What is actually happening? Were you able to retrieve any diagnostic trouble codes?

This vehicle has an OBD1 system and doesn't require a scan tool to retrieve codes. All you need is a short jumper wire or even a paper clip.

Here is a link that shows how it's done:

Let me know.
