2003 H2 ABS pedal pumps

Last week I had my 2003 H2 undercoated, now I get brake pedal pumps at my stops. It is only at the end of my stops, not during the coast down. As well I get TRACTION ACTIVATED on my DIC.

Help! Please!

The ABS controller is inside the drivers side frame rail..you may have gotten undercoating in it..as it has a open end..subject to mud, water etc..not the best location for electronics..

Got it checked today. A clip had broken off and got logged on top of the ABS sensor.

I got away with one today, phew.

gm has a problem with this you can change your hub or get rust by the abs sensor or the gap between the gear and the sensor is to great. glad you found the problem.mike
