RE: Help! My intermittent start failures
ORIGINAL: sleepwalker the fault can be deleted, but we call it a hard code because once that green and red light starts flashing, it is stored again. I heard from the technician saying that when the flashing lights occur, the computer will automatically erase itself but not permanently as the problem is intermittent so that is why it is hard for them to trace or detect the source of the problem. If can be permanently deleted, what are the steps or procedures in doing so? Awaiting your feedback. :) |
RE: Help! My intermittent start failures
after a certain on and off of the ignition key, the control unit will delete the fault from the memory if it doesn't occur again. he is right on that one.
you cannot delete it permanently because it simply record the errors for diagnosis purpose. i'll go and check my email later. |
RE: Help! My intermittent start failures
ORIGINAL: sleepwalker you cannot delete it permanently because it simply record the errors for diagnosis purpose. I was thinking whether it is possible to erase all data or information from my existing ECU and reset everything again? Some mechanics say it may work and some said it may not. Do you know what caused the code DTC B 1703 to occur? Thanks! |
RE: Help! My intermittent start failures
please do the function test and tell me the result. without attending to the car personally and using diagnostic tool might lead to a false assumption.

RE: Help! My intermittent start failures
here's some more info that might give you some ideas. if the mechanic need any information, i can send them too.
your car was produced june 19, 1995. i know all the information about it...what you got inside and outside. [IMG]local://upfiles/1/29E73601A5E2431CA907C651746B739B.jpg[/IMG] |
RE: Help! My intermittent start failures
Thank you for the attachments Sleepwalker,
I have some queries though. If you can see that I have highlighted the box in Picture No. 1 and somehow I managed to link it with Picture 2. In Picture 2, the circled numbers: 12 & 23 --> 1.0-33.0 Fault memory - engine Actual values Are the above "hard codes"? Is the MB Dealer able to delete these codes/ numbers and rectify the problem? Thanks [IMG]local://upfiles/3076/8F932EB9FF15480EA50E3E761F1928A8.jpg[/IMG] [IMG]local://upfiles/3076/F0F3BFC4FD834666B23EBDFF06FAC874.jpg[/IMG] |
RE: Help! My intermittent start failures
okay,let's narrow the problem and make it more simple. study the attachment and you will notice that only very few parts are involved, including the signal.
by the moment you open the door using IFZ, the A26/7 immediately recognize it...agree? ok, NO PROBLEM WITH THE A26/7. and after that, the door unlocks and the flashing on the mirror indicator is normal? NO PROBLEM WITH THE N54 AND A37! now, your mind is telling you that there must be a problem with CAN or the wiring from ECM to the starter! YOU ARE RIGHT! will you believe me right away if i tell you that we need to change your ECM? of course no. why? because you want me to do an actual diagnostic test! NOW HERE WE GO... I AM SENDING YOUR THE STEP BY STEP PROCEDURE TO DO IT (SINCE AM NOT THERE TO DO IT...hehehe) [IMG]local://upfiles/1/3DB2FE1259224302AD28842CEAC9D7F1.jpg[/IMG] |
RE: Help! My intermittent start failures
test steps....
[IMG]local://upfiles/1/98FD86F51B1945A7B9740319B56BDCD3.jpg[/IMG] let me know the result. it's just a matter of analyzing the faulty area, and anybody can do it. [IMG]local://upfiles/1/28CC9D5438A04104A2DF926C73591131.jpg[/IMG] |
RE: Help! My intermittent start failures
wiring diagram.
please pay more attention to theCAN controllers area network. the mechanic must know how to analyze it. [IMG]local://upfiles/1/19B7F8A555654B46827650A4207D320A.jpg[/IMG] [IMG]local://upfiles/1/08160E30A6F74B4CA6C7FE8D580FE795.jpg[/IMG] |
RE: Help! My intermittent start failures
Hi Sleepwalker,
Thank you for all the attachments posted today. I guess I will need to do a lot of homework studying these manuals. It is alright to present these manuals to the mechanic? Anyway, they won't be able to check my car (again!) until after 13th September 2004. Understanding the abbreviations and diagrams will be a tough challenge. Thanks |
