I rewrite without error


Hi tewodroski,
as i said to you in my first message I suppose you have a problem with the engine ecm.
I will make some questions and I will give you the answer that I suppose:

1) when you connect the et, how many ecm do you find? I suppose "just one", but you must find two ecm.
2) The engine cranck but doesn't start? I suppose "yes"

If my answer are correct your engine ecm is dead, part number is 2129450 and to change the ecm you must reflash the ecm with the correct flash file, you must enter the trim code of injector and you must do the timing calibration (theese works are not easy to do)

To make sure that your ecm is dead you must check if you have, with key switch on, 24v on pin 6 wire 308 yellow, and you must have ground on the pin 5 wire 200 black, if you have ground and you have 24v change the ecm!
I hope to be wrong but................

for "1) when you connect the et, how many ecm do you find? I suppose "just one""
it is one

for "2) The engine cranck but doesn't start? I suppose "yes"" yes

both your question is correct
so you can advice me how to flash my ecm but i don't understand "To make sure that your ecm is dead you must check if you have, with key switch, on 24v on pin 6 wire 308 yellow, and you must have groun on the pin 5 wire 200 black, if you have ground and you have 24v change the ecm!" step

and what is the part number is 2129450 mean

do you know what machine is he talking about M. rail9e34

"do you know what machine is he talking about M. rail9e34"
my machine is excavator 345B

You have to change the engine ecm, to by the new one you have to order, at your caterpillar dealer the part number 2129450
If you want to be sure that your ecm is broke, you have to check if you have 24v on pin 6 of the cable that arrive to the ecm, and you must check the graound at the pin 5. If you have 24v and you have ground you have to by a new ecm.
I'm sorry but I'm sure.

"do you know what machine is he talking about M. rail9e34"
my machine is excavator 345B

I don't understand your question?
I know that model, the engine is a 3176c, six cylynder,
the max hydraulic pressure is 343 bar
you have a monitor with 8 switch:
starting from the left side
1 switch is for priority to the boom
2 switch is for the priority to the swing
3 switch is for the levelling job
4 switch is for the operator mode
5 switch is for the max power
6 switch is for the automatic low idle
7 switch is for second speed of travel
8 switch is for the travel allarm

What do you think I know your machine?

[Lyonidas]

sorry M. rail9e34 i was asking for the machine series and M tewodroski answers me.

I have these machines :
- PH 5130
- PH 360C
- 992C
- 992 K
- D9R
- D9L
- 16H
- 14G
- 777B

that's all .

[tewodroski]

okey rail9e34 i am checking both pin voltage level and i will inform you tomorrow at this time i hope you can online and give some suggestion regarding to my investigation until that tank's a lot for you and other they support me tank's Lyonidas also i think both are online tomorrow

[rail9e34]

Know I understand a lot of things
You Have a very big machine, and know I understand whiy you ake a mistake when you give the password for the monitor, the 345 doesn't have the vims, because it use the maestro monitor and the password for that monitor is different.
The password is 0E323A

i don't understand monitor password where can i get maestro monitor tank's

For tewodroski
you have a pm.

[wolf864]

tewodroski i am afraid that rail9e34 is totally right for sure. I also know this machine very well and i dare say that he is right. If you have voltage at those pins and you only find one ECM then the engine ECU needs to be changed and the part number is the one mentioned before.
After the change you will need flashing of the new ECU and timing calibration using the timing probe which is special tool.
As far as i know the dealer that will sell you the new ECU will visit you and do all this job otherwise the ECU won't be covered by warantee. All the 345B excavators have very sensitive engine ECUs. The more rocky the excavation is the faster they are out of order!!
Most of the times you turn the engine off with the key switch and when you try to start the engine it doesn't respond neither emits smoke.

[rail9e34]

Hy Wolf864
thanks to given me the right, and you are right that is better call the dealer to change the ecm, because don't forget that we need to write the fls and fts and with the old ecm dead we cannot know the value.

About why the ecm is very sensitive, a lot of people think that is for hard digging or so, but is not true. If you have sis search a "tib" that speak about 2129450, and you will be surpraised to know the true.

[tewodroski]

where can i get timing probe i will buy an ecm as soon as possible and please give me a step by step guide for flashing and adjusting the timing of a new ecm pleas

[rail9e34]

tewodroski,
as wolf864 have suggest to you, is better that you call your caterpillar dealer to do this job. I will try to esplain to you why, sorry my bad english.

1 You have to know the flashfile number, and with your engine ecm dead you cannot know, just caterpillar dealer with machine serial number and engine serial number can find it.
2 You have to know the fls and fts value, and with your ecm dead...........................................(li ke first point)
3 you have to know the trim code of injectors, that is print on the injectors, you have to remove the valve covers and take it.
4 you have to do timing calibration, as you said you have to buy the timing probe, the connector adpter and the cable to connect the probe to the engine wirings.

What I can do is give you the caterpillar part number for all parts, but the other things is not to easy to find and is not so easy to do the timing calibration.
I'm sorry it is better that you call the caterpillar dealer you will pay 4 hours of labors and the ecm and you will have six months of warranty, at least in my country.
