MT35e 2.3 Bench Wiring

[theislandhub]

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

Thanks in advance for your replies.

Needed. The ECU disconnects itself when needed ....

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?

The error I receive most often is "Could not receive CAN kwp frame"

read the thread.....

with what you try to read the ecu?????

Hi mates,
I´m triying to read 2.1 on bench but no good luck. Is the same pinout like simple mt35e?
I tried opcom, avdi, original carprog, launch, ... I no connect.
I dont know what to do. Please help.
thanks a lot

carprog can read this HSFI 2.1 ecu easily.....

check your connections, and your carprog.......

Hi mate, it is not hsfi but thanks anyway
