Good Morning - I have a 2007 S-Type 4.2 that got hit on the passenger side-low speed hit in a parking lot. Had the damage fixed and I am now getting these errors; 504-brake switch A Brake switch B Brake correlation; 103- lost comm with gear shift knob; 128-lost comm with park brake control module. Is there a relay or fuse involved with this? The car seems to drive just fine. Any help would with this would be great. Thanks

 

Hi flash88,

Regarding the P0504 code, try the procedure in this document:

X350 Brake Correlation Adjustment

The U-prefix codes have to do with network communications problems. You might review the CAN info near the end of the Electrical Guide:

S-Type Electrical Guide 2006-on

Out of curiosity, what scanner was used to retrieve these codes?

Cheers,

Don

 

Hi Don

Thanks for the info. I will look into this. FYI: I have an Actron auto scanner plus CP-9180
