At my wits end !

[Jaybone]

Everybody who owns a dodge had this problem. Abs and park brake light....I replaced the rear abs sensor,complete wiring from the bulk head below the left front fender,changed the rear end oil, replaced the front wheel bearing and abs sensor. I've had many mechanics check many things....nothing....it seems like the (-) going to the rear abs sensor has 12 volts while the (+) has .097 volts with the key on......ANY Help ??

Could be the abs pump. May have to take it to a dealer to let them scan it with their special scan tool.

Unless you've already tried that.

I've actually tried another abs pump and abs computer. I'm leaning towards a match and dirty shop towels. Jk.

I would like to know why the (-) has volts where the (+) should have.

Ha I know how you feel. The "hot" ground is confusing. Does the speedometer still work?

 

[Jaybone]

No speedo...no lights tho.....no cruise.....

I'm leaning towards a new module and possibly a ECU....

That is possible. Have the dealer or any shop that may have a abs scan tool, scan the ABS codes. The scan tool they use will normally tell where the fault is.

The ABS/VSS sensor is a 5vdc signal.
