R170 will not turn over
Performed search on site, find snippets of similar problems but nothing matches all.
First, I want to state that it ran, and ran fine. Then, I left it unattended in my garage (Michigan) all winter. Like a dummy, I found the battery dead, so I charged it (on vehicle) for about an hour, got impatient, and tried to start the car using the 'start' function of the charger. Bad idea. Heard a pop, lost all instrumentation, etc.. found CCM fried. Replaced CCM. Put in new battery. Car does the following:
1. All alarm lights come on when key taken to 'run', including big triangle with '!' in the center between turn signal indicators.
2. Airbag light goes out after about 5 seconds.
3. When key taken to 'start', the starter motor does not engage the flywheel, nor does it run. There is a sound from what appears to be the fuel/air system area (just to the left of the supercharger area. This noise sounds like a motor or fan running. The sound will continue for about 5 seconds after I let go of the key, then it stops.
What I've done so far:
1. Connected Zurich ZR11 and:
a. Found no failure codes under Global OBD2.
b. C1140-128 Stored/Current/MIL "N49 (Steering Angle Sensor) Steering Angle Sensor Is Not Initialized". I believe this is due to loss of memory due to battery dying. Read about running steering wheel from stop to stop to make this go away. Found test later, will discuss later.
c. Found no failure codes under Mercedes-Benz OEM Enhanced.
d. Tried erasing ABS DTC's. Same message C1140-128 reappears.
e. Put ZR11 away.
2. Took out Xentry/DAS laptop and equipment and connected to OBD2. Ran quick test.
a. Got a big 'F' on ESP. Dove into that. Test told me to run steering wheel left/right, saw that sensor was tracking position of front wheels. The error has not returned on subsequent quick tests.
b. Got a small 'f' on PSE. Here is where my knowledge dies out. When I try to run a test on PSE, the Xentry/DAS opens something called 'HHT-WIN", through some default, and initalizes multiplexer with data. It eventually gives me a selection for model. I choose '04 170' as it makes the most sense. Then it says 'Incorrect Vehicle Adapter Cable!'... so it seems I can't go any further. Truthfully, it doesn't matter what one I select, it gives the same error about cable being wrong.
c. To save reading, I get the same cable error for the following modules, which all have a small 'f':
One thing about the ATA, I get an error message "B1709 Component H3 (Alarm Signal Horn) is not fitted or is incorrectly coded or faulty." I can't reset or test this since, when I do, it runs this 'HHT-WIN' that I apparently don't have the cable for.
Another thing - the error codes (both on the PSE and ATA) are exactly the same. The TAC (Automatic temperature control) are not, they are:
B1453 Fresh air and recirculated air flap Y11/3 (Valve block, 8 valves)
B1417 A31y1 (left dual valve)
B1416 A31m1 (Coolant circulation pump)
B1231 B11/4 (Coolant temperature sensor)
B1422 Serial interface K1 from instrument cluster to operating unit
B1418 A31y2 (right dual valve)
There is one more little 'f' code. It is associated with the ICM and reads:
B1039 FAult in CAN communication with control unit Transmission control
With key in 'run', I have everything I can think of available - blinkers/flashers work, brake lights work, reverse lamps work, headlights work, highbeam/ lowbeam works, mirrors move, glovebox light works, I can switch on 'AC', 'recirc' and defroster. Windows work, horn works, and I am even able to lock/unlock the car and have tested the alarm circuit succesfully - it alarms when the trunk is opened, or either door. I can reset the alarm with the FOB or by key. I am too chicken to try the roof, as I don't want to open a can of worms in case the thing gets stuck, but I can say it worked last fall before dead battery.
A weird thing - when I pull up the ETC module in Xentry/DAS and go to the information on it, the VIN reads all zeros. I have tried manually entering and F5 (confirm) and going back out, and back in only to find it back at all zeros. I have tried synchronizing (F7) and F5 to confirm but it ends up being all zeros again. However, with that said, the ETC module passes the quick test...
Bottom line is, I can't start the dang thing. All indications (in my opinion) look like the vehicle should start. I'm wondering if the alarm module has the battery of death problem, but does that just inhibit the firing of the engine and not turnover? It seems like everything is working but no starter to flywheel...
I have checked all fuses that I can find (one box under hood, one next to driver's door). Originally, after jumping, found 35 and 9 blown. Replaced and fuses are holding.
Also, the vacuum unit seems to run for about 20 seconds on startup too. Not sure if that is a problem or not because car always started and I couldn't hear it. Also, The module seems to unlock and lock doors fine.
I connected DAS and ran quick test and got the following errors
