I changed plug wires today and soome how knocked the brake booster hose off the manifold.
Had to stand on the pedal pretty hard when I first started the truck and went to test drive.
Reconnected the hose and have good brakes but now the ABS light is on and so it the red brake dash light. Parking brake is not on.

I tried disconnecting the battery - that did not clear the ABS lights-
Checked fuses and electrical connections - everything is ok.

Any ideas.

 

There should be a level sensor on the brake fluid reservoir. If that is damaged of disconnected the lights would come on.

 

fixed- disconnected and reconnected the connector at the controller.

pulled the RABS codes. the RABS codes can be pulled without a scan tool. disconnect the connector with the org/blk lead wire- behind the right sight kick pad.
with a jumper ground the org/blk wire and count the pulses of the ABS dash light.

16 pulse means system is OK
