We are so happy, because my friend has found a document very complete about Ford DCL Communication Protocol. We are now trying to understand that.
If anybody are interested, feel free to send me a message.

I can say something more, this protocol can be useful for some Mustang 95´.

Hello Sirs. I am here again.
We are reading de DCL document and don´t understand one thing.
1 - DEFINED EEC-IV DIAGNOSTIC MODES
An eight (8) bit value is used to encode the various diagnostic modes for
each device. The following diagnostic modes are defined in this document:
DIAGMODE Value Function
00000001 1H clear DCL error/flag bits
00000010 2H clear Continuous Self Test codes
00000011 3H display status information only
00100001 21H transmit PID values
00100010 22H transmit DMR values
00100011 23H transmit PID map
00100100 24H transmit DMR map
00100101 25H run Self Test (K0E0 or K0ER)
00100110 26H transmit Continuous Self Test codes
00100111 27H transmit PID and DMR values
01000001 41H read Parameter Identification (PID) map
01000010 42H read Direct Memory Reference (DMR) map
01000011 43H read program/data bytes
01000101 45H read program execution vector
01000110 46H read A/D substitution values
In addition, one two diagnostic codes are reserved for all link devices.
DIAGMODE Value Function
10000000 80H go permanently offline, disable DCL function
10000001 81H Set DCL baud rate
2 - I. The SBDS will specify this diagnostic mode by transmitting
the following DPS:
DPS Field Value
Module Select 001H
Module Offline FFFH
DIAGMODE Code 41H
Frame Length X
DIAGMODE Qualifier 000H
The EEC-IV will change to this mode at the start of the
next Block. All other link devices will go offline. Frame
length can vary from 2 to E slots.
How many bit are used for communication, 8 or 12 or both ??
Can anybody help as.
Thanks to all.

Is OneEng over there ??
A question for him.
I have assembled a RS232 to Rs485 interface.
But I don´t know what tension level have to use and if that interface will work.
Between DCL(+) and DCL(-) 4.53 volt DC
Between DCL(+) and Ground 4.77 volt DC
Between DCL(-) and Ground 0.24 volt DC
Between DCL(+) and DCL(-) 1.49 volt DC
Between DCL(+) and Ground 3.27 volt DC
Between DCL(-) and Ground 1.78 volt DC
Thanks, Best Regards and Merry Christmas.
PD: Has anybody P81C62A Datasheet.?? or 81C62 like somebody call it.

Here is a link, to all guys who want to follow our project..
Merry Christmas for all guys.

Here is a signal coming from ECU.
and here is the data grid.
We are waiting for some interested guys how want to join us. 8-))))

We are fighting now with Ford vertical parity check.
Does anybody knows something about how Ford uses this vertical parity.???
Thanks and Best Regards.

With this project (Just to Ford EECIV DCL ECU or PCM) any people could have a screen like above or similar, beside his instrument panel and may be thinking in most ambitious project, using a screen from a GPS too.
Best Regards and Merry Christmas.

This is brilliant work! I am doing much the same thing but am far behind you.
At the moment I have a development board with RS485 interface, and have sent the echo command 00 00 00 00 00 01 82 00 00 00 83 successfully to an ecu, and CART mode command 00 00 00 00 00 01 04 00 00 00 05 and I'm now struggling to understand the DPS message structure before I can get any further.
You have obviously solved this. Are you going to post your finding on the web?

I have tried to send you a PM, but system say me that is not allowed.
We are working hard in this project around one and half year.
I have posted a lot of information about our project and was not thinking post any more by this moment.
