I need some help. I've got an '04 Coupe that the telescopic function has now gone out twice on. It's still under warranty, but I want to know what could be causing it. Anyone have the same problem?

Basically, It will not move. I've checked fuses and haven't found any blown yet, but maybe I just haven't found.

Thanks in advance.

 

As a point of information, the wiring for the telescopic runs through a module (box) called "SCM+T" which is underneath the driver's seat afixed way up underneath the forward part of the bottom seat cushion. This is also the control module for the power seats. When I was working on my power seat problems and disconnected the wiring to the box the telescopic would not work - until I plugged it in again. You could check the connector and wires to see if anything went wrong with that. The bad news is you have to unbolt the seat and wiring connectors, remove, and turn upside down to get at everything. Extremly difficult to remove this module if you have never seen it in place before, you'd likely break a front tab off of the box.

 

Try this procedure - it often fixes the problem.

Telescoping Steering Column Calibration

Telescoping Soft Stops

After replacement of the seat control module, it is necessary to program the telescoping soft stops. Each soft stop is a programmable end of travel that is set approximately 1.3 cm (0.5 inch) from the mechanical end of travel. The steering column has a soft stop set at each end of the telescoping in/out movement. The system uses soft stops to prevent wear on the system by ensuring that the steering column movement stops before it reaches its mechanical end of travel in any direction. The soft stops are initially programmed at the factory. The stop positions may be reprogrammed, which is necessary any time the seat control module is replaced, as described in the following procedure.

Telescoping Soft Stop Programming Procedure

1] Turn ignition to ON, leaving the engine off.

2] To set the telescoping in soft stop, press the telescoping COLUMN IN switch at least eight times or until the column moves.

3] Press the telescoping COLUMN IN switch and hold the switch until the column travels all the way in, and continue to hold the switch about a second after motion stops at the mechanical end of travel. The soft stop for the column in position is now set. The seat control module automatically goes back to the normal mode of operation.

4] Repeat steps 2 and 3, using the COLUMN OUT switch, to set the column out position soft stop.

 

Does the column work when you set and use the seat easy entry mode?
My column works fine then but will rarely work with the column switch, that I have replaced.

 

THANKS PATCHES,
I replaced my SCM and did not re-program the soft stops; I'll do them now.

 

I've got to try it tonight. I'll let everyone know. Thanks

 

Patches -- You are the one!!!!

If your ever pass thru or if I see you at an event, the first beer is on me!

 

FYI - Your seats have soft stops as well. Keep tapping the down button to reset em.

After replacing a memory seat module or adjuster components, it may be necessary to reset the adjuster motor soft stop locations. When the repair procedure has been completed, operate the seat adjuster switch in every direction until the seat adjuster reaches its mechanical hard stop by repeatedly pressing and releasing the switch as necessary.

 

iT SOUNDS LIKE YOU ARE IN THE KNOW.
Does anyone know what module is the Memory Seat Module (MSM)?
There are two modules under my seat in my 2005 C6.
One black larger module with three plugs marked: GM P/N 15144164 Lear P/N L0020248AB '02
The other a smaller grey module with two plugs marked:
