Hopefully exit up the runaway lane?
(and hope the TCM starts riding a clutch somewhere to manage engine RPM...)

I have hit 80 once going downhill on a very steep downgrade, with a stiff tail wind. I was doing 70 on a flat before I started down the hill. The brakes were cool, and I had no trouble dropping to 30 or so in short order. Now doing that again within a couple minutes? I would likely see quite a bit of brake smoke.

When i'm coasting under cruise control, the transmission will downshift for braking when i exceed the set speed by 5 mph.

According to page 60 of the 2006 Transmission Diagnostic manual, the Sprinter will set an error code (engine overspeed) in both the ECM and TCM if you reach 5100 rpm.

I know that i've run across an up/down shift-point list *somewhere* (it was involved with resetting the transmission's "learned" shift points), but i can't find it at this time

(page 8E-8 in the 2006 service manual).

ShiftPoints.png

They don't specify if that's for 16" or 15" wheels, and i think we have to assume it's the 3.73 differential.

--dick
p.s. the same shift-point numbers are in the 2003 service manual, too. Page 8e-7.

One more, I am wiring the blower to work both off of engine power or aux. The fused ignition sw output, is that the same as what closes the relay between the batteries?
What fuse is it fused by? It does not say in the 06 body manual.

This also seems to power the most of the climate modual show. So I need to fuse my aux power likewise.

Step one: don't use the Body manual, use the full service manual.
Fuse numbers are covered in section 8W ... BUT ... for anything on "fuse block 2" and "fuse block 3", the actual fuse positions vary from Sprinter to Sprinter, depending upon your option mix (and what Fritz was smoking that day).

*Your* fuse list is pasted on the back of the fuse panel cover plate. (there's another list on the inside of Fuse Block 1's cover, too (under steering wheel))

For the cabin blower, it's a 30 amp fuse as Fuse #21 in Fuse Block 1 in a 2006 (first service manual i grabbed) and in the 2004 manual.

Oh... your diagram is for the big fan in front of the engine?? Why run that off the Aux battery?
Oh, well ...
THAT fan is "Fuse #1 on the Fuse/Relay block" ... which is going to require a photo:



See the two **horizontal** green fuses? In my Sprinter, the Aux fan is (or may be, i haven't tested by yanking) the one on the right.

Ain't Sprinters fun!

--dick (gee: your posted diagram DID say that: Fuse 1, and "Fuse/Relay Block")
p.s. i looked up the service manual's idea of the Rear Window Defogger's fuse position: #10 in the Fuse/Relay Block
:idonno:
I probably stole my photo's assignment of those two from Vic's similar photo.

Well, if you mean did Mercedes use the "ignition switched" power for the isolation relay: No.

They use the "D+" signal, which only comes up when the alternator is actually *running*.

If you have the EK1 strip, here are the three posts:



That terminal strip is mounted on the center wall of the driver's seat pedestal. i.e. close to the parking brake handle.

In the service manual, those three posts are called the "Body Plug Connector", and shows up on page 8W-11-28 in the 2006 manual. (or -29 in the 2004) ... and again on pages -39 and -40.

It is very complicated, but I am only concerned w/ the 2nd pic, "to fuse block 1 fused ignition sw output". What is this fused by.

I do not yet have the 04 full manual.

Default Re: A few Questions

(drat!! ... something caused my long answer to disappear in the edit block. Sigh, redo)
2004: http://diysprinter.co.uk/reference/2004-VA-SM.pdf 2006: http://diysprinter.co.uk/reference/2006-VA-SM.pdf

Quick synopsis: i couldn't find the source of the "ignition-switched power" your diagram talks about. Read on...

OK ... we go to section 8w-42 Air Conditioning/Heating

We look for the Automatic Temperature Control Module's (ATCM) C1 pin 21
That's done by flipping pages until we see it.
Along the way, we notice that *other* fuses feed the controller.
On page 8w-42-6 we find C1 Pin 21 ... Oh, joy... it goes to a *splice* (S201) and pin 10 of the Auxiliary Heater's 7-day timer.
The signal (in the ATCM) powers a relay's coil, which connects UNswitched Battery power to the cabin fan resistor block (so that the timer can turn on the fan when the Aux Heater is running)
We continue page-flipping in case something interesting happens... yup
The very next page duplicates page 6, except with the "alternate" resistor block that some Sprinters have.
we flip onward... i don't recall (from 1st attempt to write this) any surprises until:
Page 8w-42-17: Splice 201 goes to the ??TCS Switch (ASR)??? in the *braking* system??? (8w-35-4 and -2)
and also to the "Additional Heat Exchanger Switch" .. luckily i have one of those ... it's the optional under-floor cargo area heater core (with two-speed fan).
Looking at the Aux HEater 7-day timer documentation, pin 10 seems to be an input (they give the example of tying it to the ACC position on an ignition switch)
But we're not seeing power being *provided* to S201 ??
Note that S201 doesn't have an off-sheet page reference. That means that *all* of its connections are (theoretically) shown on *this* diagram.
There are other areas in the schematics where they flat-out missed wires. This may be one.
Page 8w-42-18 shows the Aux HEater manual switch.
On both of those two pages, the DRL (daytime running lights) relay is shown... that is somewhat a "switched ignition" circuit. MY van doesn't have DRLs, so i've never tried to chase those down.
Page 8w-42-19 repeats what -17 showed, plus expands on the 7-day timer.

Remember the reference to the TCS? On page 8w-35-2 we find S201, and it's going to the ASR on/off switch, and thence (if on) to the Anti-Lock brake controller on -4 to the TSR switch sense.
------------------
OK: it would appear that S201 *should* be powered by a switched-ignition source, but those diagrams don't reveal it.
I fear that the manual will NOT have it shown, since their drawing software should self-cross-reference it.
But, i'll got back to page 8w-10-4, where the list the fuse assignments (kind'a) for FB1.
(we note that S201's colors were "BK/BL/DG" ... black, blue, green)
None of the fuses on FB1 show that color set. But at least we can see that fuses:
4,5,6,7,8,18 and (accessory) 15 are ignition-switched.
((15 on my own fuse list is "radio(switched) and central timer unit" (i.e. wipers)))
------------------------
Soooo.... i looked in the 2003 service manual ... the only difference there is they're calling the pins that talk to S201 "S201 Common Circuit" instead of "ignition switched output" ... yet the diagram you posted says what yours says (no mention of "S201").
---------
Helping to confuse matters is that the Auxiliary Heater *also* has a BK/BL/DG wire, going to a fuse on fuse block 3 (one of the random fuses on the seat-side panel).

So that's where i'm at now ... without pulling fuses to see what dies (or tracking down all of the OTHER fuse-feeds from FB1), the US documents don't say where S201 is powered *from*.
According to the 2006 service manual S201 is physically located behind the AC control panel.
... along with S202,210,218,252,253,256,300,301,310,325 and 364. Whoopee.

--dick (my head aches...)
p.s. i have the 7-day timer, so in theory i could probe pin 10 on that connector and pull fuses (with ignition on) until it reveals itself.
... at the moment i'm not prepared to do that... (sorry)
