Electrical question.
Got problem with my keyless go. Driver door unlocks with the hand but doesn't lock with a button on the handle, rear doesn't lock or unlock. Passenger side both doors lock unlock no problems. keyfob locks and unlocks everything no problem
Its definitely not the handle itself because i swapped it up with right side, left side worked on right side but right side didn't work. so handle is fine problem must be somewhere else, not in the handle.
Rear tailgate doesn't go up or down on its own.
Rear SAM nice and dry same with the module by the pump at the bottom of the trunk is nice and clean i open them up and made sure no water damage.
You said "Driver door unlocks with the hand but doesn't lock". Why don't you have a code for that but instead you have a code for the rear door?
For code 9095, have you removed relay KR in the Load Compartment Fuse Box? Remove KR and scrub all legs with steel wool. Then insert and remove relay 5 times and see if that helps.
For code 9111, there are procedures to check the handle but you would need Star to actuate it.
For code 9502 you will have to check the voltage at the Rear-end Door Closing Module connector #2, wires 3 Brn. and 6 Red.
Post the results, YES or NO.

Check the voltage at the rear door module. No voltage. When i press open/close button on the rear gate i get 08.48 V and i notice almost every time i open the rear gate or try to press that button i hear like a weak whistling sound from somewhere, cant figure out from where.
Code for 9095 got out of rear SAM
Removed KR relays replaced them with 2 new ones cleaned the legs with fine sandpaper inserted them in and out about 5 times. Cleared the code, looks like its fixed Thank you!

After clearing all the codes i scanned it again after driving for a day i got 2 codes.
9030 The switch Raise and lower tilting/sliding roof >> from HBF Rear Control Panel Module
9502 connection to component B24/16 (Rear-end door opening angle recognition sensor) is interrupted or has a short circuit >>> from REDC Rear-end door closing module.
Please help, Thank you!!

Checked sensors on each side i get about 3.9 OHMS. Is that about right?
What i did notice that the module was kinda warm, don't know if its normal or not. Another thing i noticed that the module that in the car now have a different part# than the original to the car when i got the car.
Car came with part # A1648701126 replacement i got, that is in the car right now part # is A1648203185 would that make a difference? Don't know how i got module with diff part#

Should i get the right one and see what happens?
What is B24/16, is that the sensors on each side?

Than you for all your help and the information,I really appreciate it!!

this problem kicking my butt.Front SAM no codes, rear SAM no codes!!!
What is component B24/16 rear end door sensors? can anyone tell me? and where are they located? thank you
Major Dundee no longer with us! RIP.
Would you like to share what happened to this problem. I have exactly the same issue with exact same code. I have a 2008 ML350. It happened after I changed the faulty hydraulic pump. The liftgate operates normaly except on function. The key fob can close the liftgate but just cannot open it. It opens and closes with the switch of tailgate and the switch on the driver door. It just doesn't open with fob. The hydraulic oil is filled to the right level. Thank you for your time.
