Hello all. I changed out my rear brake pads on my ‘16 TLX V6. In the process I dropped my parking brake acuatice and it cracked in all the important places. I ordered another one from the dealer and installed it today. After installing it my car is still throwing up the Check Parking Brake/Brake Hold messages and it doesn’t seem this actuator is functioning on that side of the car, while the other appears to be working. Also, when in drive, the car is telling me to release the parking brake.. but it is released.

anyone have any ideas?

Welcome to the Forum!
Those electronic Parking brakes can be fussy. Check all the wires/connectors associated with that side of the car/tire. Let us know what you find.

I spoke with a technician at my local dealer. He said that the parking brake should be placed in maintenance mode through a scan tool prior to doing a rear pad swap. He said to disconnect the actuators, put into maintenance mode, connect actuators, disable maintenance mode, and All will be good. He said I would need a scanner tool to do it, but didn’t know if the cheap ones can. Anyone know how to access the ABS menu with a OBD tool??

Yes, this is the correct procedure by using a scan tool. This is a good lesson for everyone when it comes time to do the rear brakes. Either have a scan tool or take it back to the dealer. Most independent shops should have the necessary scan tool too.

Is this "scan tool" a common item that the garage mechanic could get?

Well.... crap! Sorry to hear of your troubles, but glad to see it posted. I've done my own brakes on every vehicle I've owned, and has no idea that the rears on the TLX had this special requirement. Thus will need further investigation.

Did you find out what’s going on? I’m in the same boat

I know this is an old post, but since a new comment was made, I thought I'd share my experience.

I changed out my pads and rotors early last year (2/2022) w/o the use of a scan tool and had no issues w/ the parking brake. I followed the procedure to remove the actuator and use a TORX driver to turn the worm shaft 360 ° clockwise. After I was finished w/ the pads and rotors, I made sure the actuators we're good and clean, replaced the seals on the them w/ new seals to which I applied a little white lithium grease and reinstalled them. When I started the car afterwards I applied the parking brake, which took a little longer than normal, but didn't trigger any errors or warnings.

Should I try taking everything apart and cleaning them and reassemble

You could try that and make sure there's no obvious damage to the connectors, actuators, and seals. If it persists, you may need to replace one or both actuators. My service rep informed me that they had at least one instance where just removing the actuator resulted in it failing.
