Title: EDC15P ECU Boot Mode Post by: n0ble on December 13, 2013, 09:02:10 AM Hi All,
So i bought a cheap EDC15P ECU to practice with for boot mode and also to practice removing TSOP. However my first aim before i move onto desoldering the TSOP is to gain bootmode. Here is the ECU, it was removed from a Golf 1.9TDI 115BHP early 2000. (http://postimg.org/image/g93rcy6mr/) So here is what i have tried: 1. Manually connected MPPS lead to Ground, +12V and K-line - this allows me to run an ECU ID, but i cannot read a file from the ECU. I keep getting a message to tell me to remove dash fuse, and i press OK but then MPPS fails. I also tried (Slow Read - Recovery) from the options but this makes no difference. 2. I Manually wired up to Fgtech: Green Wire - K-Line then appropriate ground +12v cables. When i hit ECU data, the bar quickly progresses to 100%, then it starts from 0%, goes to 14% then 28%, then i get an ECU Wake error. 3. With Fgtech again - Wired up the same as point 2 but i tried boot mode. All Powered off with pin 24 grounded. Power on and leave pin grounded. Then try ECU data, this time it does not quickly go from 0-100%, but goes straight to the 14% then 28% cycle at which point i get the ECU wake error again. I powered off the ECU then back on with the pin grounded this time for 10s and i get the same symptoms as above straight to 14% then 28% then fail. After powering everything off, with no boot pin grounded the ECU now responds as it does in point 1 and 2. What i have not tried yet is boot mode with MPPS, but i reckon i will get the same fault. Is there something i am doing wrong or has anyone got any suggestions? I want to get boot mode nailed before i move onto the eeprom desolder.

Not sure this matters, but the car it came off was AJM code. (http://s21.postimg.org/4jzrozfo7/IMG_20131213_151039.jpg) Title: Re: Post by: n0ble on December 15, 2013, 02:02:31 AM After messing around I found that this ECU is not actually an EDC15P. EDC15P came in 2001.
This is a Bosch non descript moronic which cannot be written over OBD. So I will continue to play and start practicing my desolder and resoldering skills. I may well kill the ECU but it doesn't matter as it was very cheap. |
