Jettadan1 :

Hi I am Daniel

Jettadan1 :

Your probable cause is a bad electronic brake control module. But Connections and wires need to always be checked.

Jettadan1 :

I can supply testing and diagram if this would help if you are doing your own work.

Customer:

Would the pump/pressure switch also need replacement

Jettadan1 :

No not if those are your only codes.

Customer:

I thought that might be the case. I was told that the pump might also be defective which would in turn take out the replaced control module which they referred to as a relay of sorts.

Jettadan1 :

yes the relay is intregrated into ecbm and is not servicable

Jettadan1 :

If youhave any questions or requests please let me know.

So if the pump/pressure switch was also defective there would be an additional error code. In other words, the switch does not need to be replaced at this time? My service advisor suggested that both units be replaced to safeguard damage to the ebcm.
Expert:  Jettadan1 replied 5 years ago.

he should be able to a fuctions test on the switch and prove it is bad. yes usually if there is not a error code there isnt nothing wrong with it. But. I have seen sensors that were bad that have not thrown error but I tgested them with a scanner and did a funtions test and compared it to a know good running pattern in my scanner. My program as his should have a complete program. Thanks for letting me clear that up for you.
