hello
Can anyone say which version of ECM is on the CX613.
The reason for this question is the ECM has 3 plugs and when I checked the VMac3 and VMac4 diagnostic manuals, it makes reference for 2 plug ECM.
The Manufacture date is 2004 with EGR system
Thanks

i have read about using the cruise control switches, what is the process for that ?
Here is the procedure
BLINK CODE METHOD
The V-MAC III system is capable of flashing a
two digit blink code for each detectable active
fault in the V-MAC III system. These codes are
displayed on the Electronic Malfunction Lamp
(EML) which is located on the dashboard. The
primary reason for the blink code is to allow quick
diagnosis of active faults in the system without
requiring an expensive troubleshooting tool.
To properly activate and use the blink codes,
follow the steps listed below.
1. Turn the key ON and wait until the Electronic
Malfunction Lamp’s two second power-up
test is finished.
2. There must be an active fault for the lamp to
remain ON after the two second power-up
test.
3. With the Speed Control ON/OFF Switch in
the OFF position, press and hold the
SET/DECEL Switch until the malfunction
lamp goes OFF.
4. The malfunction lamp will remain OFF for
approximately one second.
5. Immediately after the wait time, the Vehicle
Electronic Control Unit (VECU) will begin to
flash a two digit blink code. The two digits of
the code will be separated by a one second
idle time (malfunction lamp OFF).
6. Each digit of the blink code may consist of
up to nine ON/OFF flashes. The ON and
OFF time between each flash will be one second.
7. The ON flashes of the malfunction lamp
must be counted in order to determine the
two digit blink code.
8. Only one active fault will be blinked per
request. There must be a separate request
for each active fault, where there are
multiple active faults present in the system.
To request another fault be displayed, hold in
the SET/DECEL Switch until the malfunction
lamp goes OFF. The blinking sequence will
begin again after a one second delay.
9. If a fault blinking request is made while the
Vehicle Electronic Control Unit (VECU) is in
the process of blinking an active fault, that
sequence will stop and the next active fault
will be blinked.
10. If an active fault is cleared while the Vehicle
Control Unit (VECU) is blinking that fault, the
procedure will not stop.
11. After every complete blinking sequence, the
malfunction lamp will return to normal. It will
remain ON for active faults and OFF for
inactive faults.
12. The Vehicle Electronic Control Unit (VECU)
will provide blink codes for active faults
registered by both the Vehicle Electronic
Control Unit (VECU) and Engine Electronic
Control Unit (EECU).

hey guys
i need some help here. i have a 2003 RD688S with the AI 350, i had a problem with poor throttle response and no power after 1800 RPM,
i had a local shop check fuel pres, it was low so they put a new pump on and they also adjusted the valves. the truck ran much better for a bit. the last couple of days though it's been a real dog, at 1800RPM it's flat..no power at all but after a storm rolled through today and cooled things off the truck run's 100% better, it would pull through 2100RPM. all the filters are new and the engine speed sensor has been replaced. it seems to me that there is bad sensor somewhere. the electronic malfunction light comes on very sporadically, maybe once a month, more or less. i haven't had the codes scannned thought. is there a way for me to scan the codes without a scanner ?
i now know that air tempature makes a huge difference on performance.
thanks for any input.
You could pull codes from diagnostic switch on dash board. If the dash is digital then there are two push switches at the side or you could use the cruise control set resuume switch to display the codes.

You may have debri in the oil pasages which is creating the failure of the sensors, I suggest that you use air pressure 100psi and blow the the port where the the sensor is fitted. Another thing using tefelon tape or thred seelant on the sensors is not advisable

you need to investigate the fault code if you are not getting power to the injectors

What system do you have V-mac 1, 2, or 3. Normally on the older models there is a diagonistic switch by the steering column under the dashboard(usually amber in color)

Can someone identify this ECM/ECU
in Engine and Transmission

Thanks for the response
Can you say if the vmac111software will communicate with engine
