As I mentioned in post #17...the image of the rear relay locations that belongs to powers1 (he doesn't have any model/model year/build date in a signature)...it apparently is the pre-face lift layout.
I was just reading this information this morning about the e53 X5's face lift changes (starting with 10/03 build date)...and below is some info about the SCA (soft close actuator) and the rear relay/fuse box layout below...the SCA relay is the one on the far right in the rear right cargo area: This is an image of my 2006's rear fuse box...SCA relay is on the purple relay on far right FACE LIFT layout of rear fuse carrier (10/03-up build date)

the rear hatch is locked out for 10 seconds in case of accident - nice to know...
the SCA motor is not activated if the voltage is below 9V... is there a valid method to open the top gate (with a pull-string) AND, more importantly, the lower gate, when the battery is dead??? the reason for the question is, when the battery is dead, even if the rest of the car is unlocked, to get to the battery and to replace it, one needs to open the lower gate, flip the floor board or pull it out, and then deal with the battery... dead battery - the lower gate is locked... so... is there a "factory prescribed" method to open the lower gate to replace the battery? |

Qsilver, thanks for all the info!
Would you happen to know where the hall sensor is? Is it a serviceable/replaceable part? Given the info you posted, one problem could be the hall sensor not sending signal to close. Or the General Module :/

Yep...the manual release for the face lift's upper & lower halves is in the owners manual. And you can see the lift gate's manual release cable in the diagram below...it's #17 (bottom right corner in illustration): Quote:
Below is the schematic that shows how the early tail gate has a micro switch...and the later tail gate has the newer servo lock with the hall sensor:

Thanks Q
the top liftgate - i knew about it, that is the "pull-string" i was referring to earlier... it is a Federal mandate, to have a manual release from a trunk, after several "high" profile cases of kids locked up in the trunk (they make those pull strings glow in the dark)... too bad it wasn't in effect at the time of "mafia" transporting their "friends" in the trunks... lol... the lower gate is something new - i guess, reading the manual pays... lol... so, there is a valid method, that calls for removal of a trim - nice to know... thanks |

No problem...you posted back before I could finish up on the prior reply but...yeah...the bottom tail gate isn't that hard to open manually.
When you go out to check it out...if you lower the the bottom half...the top panel (the one closest to the interior) can be flipped up with your fingers...try at the edges (start in the middle where the two protection pieces meet). Nothing really secures it (which was surprising when I tried it)...then just follow the manual's instructions. Thank gawd I had all this time on my hands...football and snow...I'm going to dread tomorrow morning...it's still falling and it's about 8" more on top of 8" that fell New Years Day...and by morning the temp is suppose to drop from what it is now (approx 30°...to -12°. I probably need to suit up and knock some of it down while it's still close to 30°.

Q, thanks for the additional info!
If I remember the mechanism correctly, when you close the lid the striker engages the latch, the latch locks on the striker, then the mechanism pulls it all the way closed. I am thinking the hall effect sensor senses when the latch locks onto the striker, then sends this signal to the GM, then the GM sends a signal to the motor to pull it closed? I believe the soft close system starts with the mechanical latching, and if that portion broke, the soft close process cannot continue? My latch will not lock, even when pushed manually. It just springs back open. Sooooo...I saw a post where a spring breaks in the latch (pre-facelift though) results in the latch not engaging. I am thinking I have a similar problem in the mechanical portion of my latch. Thing is these things are riveted shut, but $300 is a big motivator in attempting a repair!

Got it working!
After checking all related fuses and relays (thanks again Q), I removed the door latch assy from the tailgate. Though the mechanism itself is riveted together, there was a portion with a clipped on plastic cover which I removed. The mechanism was stuck to open for some reason which is why it would not latch. Imagine trying to close a door while the door handle is in the open position. Anyway there was nothing obviously broken in the exposed mechanism but there was a lever that if held up allowed the mechanism to cycle normally. So I rigged a plastic stop to contact that lever and keep it held upward. Works so far. Dont know how long it will last though.

(did you stay up all night working on this?)
Still kinda sounds like a problem with the hall sensor in the actuator. I'm not an electrical guru...my knowledge is similar to someone being able to understand a few phrases and words of a foreign language...but not enough to be fluent.
