So so so, im finally undertaking the famous ABS/Brake warning light issue on my little baby Astro.

i've watched the video, read the thread, googled it, and im wondering if anyone have a comprehensive list of what i need, and it's exact location?

i've seen conflicting screw sizes, and conflicting location details and i want to get this right on the first go.

id be so so so grateful if anyone could help me out. what exactly do i need to do a full and proper job, and where exactly is it and what procedure is best to remove without issues.

thank you thank you thank you for letting this forum exist. 🙏

The unit is mounted at the frame rail underneath the van at the drivers seat. This likely will not be a job you can pull off in a day even if you had all the right tools.

Have you checked the codes? What error codes are you getting for ABS? Are you positive the wheel speed sensors are not the culprit?

I am assuming you think the well documented ground inside the unit is the issue.

First, check to see if the power wire to the unit is still connected. Its a big pink wire. It tends to burn out at the connector. If it is all in order, commence pulling the cover off the ABS.

The cover is facing the underside of the floor pan...super tough location. There are 10 or so T14 screws which have to be removed in order to free the board.

Float the board ground per the online video instruction and reinstall.
