Needed. The ECU disconnects itself when needed ....
Hi All,
Was wondering if some one can tell me the need of the relay in the MT35e wiring diagram? I assume this is as it is in the vehicle, However I'm trying to connect the ecu on the bench. Does one still require the relay?
The pinout I have is as follows:
1 + 63 - Ground (12V- on Bench?)
2 + 14 - kl. 30 (12V+ on Bench?)
16 - Main relay control (12V+ on Bench?)
52 - kl. 15 (This one being ignition and before the relay in diagram below, Is this designed to redirect the power away from the relay thus switching off 12V+ to 2+14 & 19 in in diagram below when switched on?)
11 - CAN-H
43 - CAN-L
54 - K-Line

Thank you Bllinda
Having got out a relay yesterday and set it up as shown, It appears the relay is not powered until the ignition switch is pressed activating the 12V circuit in the ECU.
Next issue I have is I have a carprog 10.93 clone and I am trying to read a damaged ECU (Pin 16 corroded) to write to a new donor ECU. I have changed a capacitor for a 103 resistor as suggested online in the A1 adapter, But it wont read EEPROM, it reads EEPROM2 hit and miss and won't read flash. I have ordered a new MCP2515 and will replace that when it arrives but does any one have experience with carprog and mt35e they can share with me?

Please till me how the problem solved?
because i have the same problem ...
Hi mates,
I´m triying to read 2.1 on bench but no good luck. Is the same pinout like simple mt35e?
