Question

My ABS light is on and it is throwing the code CO110 and I need to know what the problem is?

Answer 1

C0110 ECBM detects a open pump motor circuit , a shorted pump motor, or a seized pump motor or ABS pump.

For this code condition, power and ground should be the first area to check, power will be from a fuse listed as BRAKE fuse 51 which is a 10 amp fuse, the ground is also important to check, listed as G304, The next step would be to determine the operation of the ABS motor, this is done with a factory level scan tool that can read ABS code,

​Here the location of the ground, this is important area to check if missed you may end up replacing the ABS motor only find it just a ground fault.

​ The connection for the ABS motor , you can separate the connector , and inpsect the connection for any corrosion , this is where a factory scan tool is used to determine if the ABS motor is faulty
