Today’s Symptoms:

This 2004 Dodge Caravan ABS light problem came from one ATS customer while driving home from work. What’s funny was while he was watching the speedo gage, it showed zero but the vehicle was running roughly around 30 mph.

Diagnostics for 2004 Dodge Caravan ABS light:

This problem is best tested by having an abs scanner so the exact abs circuit could be checked. And this is not an easy task since most of this abs code can only be taken by Chrysler’s DRB scanner or those expensive generic scanners (cost of which can run over a thousand dollars).

Having said this, the next best option is to have an ABS wiring diagram of this particular vehicle. And having a good look at it, the best way to start is to check all 4 wheel speed sensors of the vehicle.

Here are some ABS wheel sensor tests:

1.) Each sensor has a 12v supply and a signal wire. Both wires connect to the ABS controller located at the right side of the engine compartment. The signal wire usually reads between 0.5v to 2.0v depending on vehicle model. Furthermore, you are better off checking the continuity connection of the sensor wires up to the controller in case there is an break or open connection. Next, check the sensor itself against the tone wheel for dirt and possible wear. There is a specific gap between the wheel sensor end and tone wheel which is available from the vehicle abs specs or ATS can supply it to you.

2.) If the wheel sensor is replaced, the abs indicator light can be reset by driving the vehicle for upto 15 mph. If this does not correct the problem, check the ABS controller ground terminals #1 and #16 with key on engine off. Anything higher than 0.250 volt means trouble and it’s about time to take it to the dealer.

Notes on 2004 Dodge Caravan ABS Light:

Do not attempt to do this ABS repair on your own unless assisted by a licensed mechanic to prevent damage to your ABS circuits.

On most 2004 Dodge Caravan light problems, it is mandatory to take an ABS training before handling this kind of repair.
