My ABS light came on. Took my truck so they can put the computer to see what was the problem. The computer has no communication with the ABS module. How can I check if there is power on the module and it has enough ground source? Thank you

Good afternoon,

The first thing I would check is the powers to the ABS module. if you have powers to the module, good chance the module is bad. I attached a diagram for you to view and a video that show the module being replaced.

I have a z71 1500ls Silverado and can't get the abs module out due to no room for a small rachet.

Will the ABS Module and Pump from a 2002 S10 replace the one from a 2002 Silverado 1500? They look identical and have almost the same number on the tag which is 133547? (I can't read the last 2 numbers).

Thanks

I doubt that it will, the braking systems will be different I feel, just to be sure you will have to check that part No, that will give a good indication, we do not have access to part No's on Mitchell 1 at present sorry.

If you have cleaned around it then try using a rubber mallet or similar and tapping around it lightly to remove it.

Disconnect harness first, wash all contaminants for unit. Unbolt bracket from frame remove unit then unbolt bracket for abs unit. However for install this has to have a pro use a scanner to program it to your vehicle.

Can you tell me how to remove the abs module from the Silverado 2500? There is less than 1 inch from module to frame rail making it impossible to remove torque head screws. Yes less than 1 inch. Thanks Keith

Can you disconnect the harness and then just remove it from the mounting bracket on the frame rail first?
