Good Morning

My name is cClaoments
new to the forum and I is not too much or post my topic for someone draws help I French,

I have a problem with the gearbox A604 4 speed Chrysler Voyager 2.8 CRD S4 2006
transmission when the time had led speeds went well up to four, once we remove the foot on the accelerator and the speed is less than the 2 and 3 and we are accelerating the speed of the second block.

Note: The A604 has been repaired completely replace steel and friction disc with overhauld kit (OHK) molded solenoid piston converter block, the restoration of the valve body.
After mounting the gearbox A604, we made the diagnosis (MD802 the altar.
The altar of MD802 we said before diagnosis, information: the transmission is in box!
Error code:

1 * DTCs:
- Error Code: C0015 Relay Output Always Off. (Active)
2 * Trouble code:
- Error code: P29. Missing wheel speed rear left. (Active)
- Error code: P31 missing rear wheel speed right. (Active)
3 * Trouble code:
- Error code: FWD sensor Riser / Out of Range Low (stored)
- Error Code: Charging Voltage / Low Message (stored)
- Error code: sensor before Riser / Out of Range (stored)
- Error code: FWD Riser / Sensor Out of Range (Active).

Our fuse relay center and IPM is written PCM.
he TCM on certain vehicles not written.
and our pcm relay is left just below the large relay
write starter relay.

This pcm relay before there is no power that arrived
we removed all blocks IPM FUSE center of relays, and clean all electrical connectors of the circuit
as PCM below the module conduteur wheel.
connectors blocks solenoid Boitie ECM and electrical outlets.
we redid the mase distribution side, taking mase chassis side rails driver

After instalation battery Volte 12.68.
happened current connector tests against the PCM relay 2 relay oké. (12,67volte)
the speeds of the test vehicle still does not change.
clear the default code
no test vehicle.
diagnosis, even the default code always returns.
ducts open, control files
I believe no files found cut.

The dismantling of ECM connector plugs
there is an issue leaves just inside that melted and went to the connectors on two sheets of ECM
we tried to clean it with a cleaner touch repeatedly
toujour it a kind of school that comes ECM connector plugs
right now we think the problem is with those cards that do not communicate with the ECM and other module and transmission
NB: in diagnostic repeatedly


NB: in diagnostic repeatedly
imposible to intéroger elite ECM MD802 said:

1. Secure the ignition is turned ON
2. Check the cables between the test and vehicle diagnostics
3.Check vehicle Whether the battery is charged
4. Check if the system is confugured for the vehicle

on line 15. 16. PCM block 17 which is below the driver's side go
Lines 15 and 17 shows, pool from 3.9 volts to 3.7vols

what matters is whether the ECM on this voture has a role in the transmission with the other modules, if the current does not fall and ECM station involved to Cole on the connector may be the problem,
and this tester problem is not communicating with the control unit
or when the ECM is off services (hs)

sorry for the bad english

Thank you in advance for your help and compréhenssion.

Best Regards

 

As you have a stored charging voltage error code I would start off with checking that the alternator is producing the correct voltage. You mention battery voltage is 12.67v. Is this with the engine running or not?

 

Hello: royal100805
Thank you for the time you took to read and respond.
Engine running: battery charging voltage is 13.93 volte stabilized engine idling.
With the engine off voltage of the battery is 12.40 volte
the voltage of the battery before was 12,67voltes engine off
and before the charge voltage of the battery with the engine running
idle time had gone up to 14 and some flip
but today it is 13.93 volts with the engine running
in slow motion
I hope I have answered your questions

I saw on another forum that we must control the two lines of the alternator output regulator liason with PCM on pins 20 and 57
but with testing the scheme I've found only concerns Chryslers until 2002 and mine is 2006 and the colors of the lines does not correspond with 2002
I have on my alternator 2 files controller output 1 brown with a white band, is this happening directly to the PCM with the same crayon?
or it goes by another module.
and the other as black with a brown belt
and given that I can not communicate with the ECM ??
thank you

 

And just I forgot if it can help you help me solve my problem the vehicle has 263000km, so I do not know if the brushes are worn regulators
or when there is one or more diodes of the generator is not working view of the vehicle kilometer
How to test the alternator regulator
or if someone can help me with an electrical testing scheme latest chrysler

thank you

 

Ok The alternator sounds good voltage wise. Now I would check power at the transmission control module to makersure you are getting the correct voltages in and out.

 

You talked about the PCM which is under the driver's side wing ??
Can you tell me how to check the voltage at the output of the PCM with the multimeter,
is what are the lines No. 15, 16, and 17
engine off or engine on ?
Contact on or off ?

But I'll redo the test tomorrow
to do I put my multimeter + files on the No 15 and - multimeter on - battery and I repeated this process for the other test files
ignition on
is what testing has been well realized or not ??

Hello, royal100805.

Just say thank you for everything, for the help you gave me and the time you took to read and answer my questions.

I finally found the lead that was cut,
was the leading No. 16 out of PCM that went EATX relay internal filaments was cut inside and outside the sheath was well full, not possible to see that the file is divided.
After repair of the cable and any other cable removed,
Blanked defects with the suitcase Autel Elite MD802,
speeds normally spend very soft, no default


No disrespect to Chrysler engineer beams are very poorly done inside
all queues are folded ised,
normal they cut withdrawn when the transmission or engine vibration or ground

thank you again
Happy New Year 2015 to all of you and your family in this forum and out
