2.2.3 – Connection of RS232/CAN ECU Bridge to the ECU 

 

With 

RS232/CAN ECU Bridge

 it is possible to sample data out coming from the vehicle 

ECU or OBDII plug. To know if the vehicle ECU is supported by 

ECU Bridge

 and to know 

how to connect the vehicle directly to the vehicle OBDII plug refer to the document 
downloadable from AIM corporate website “Download area”, “ECU connections”. 

Always refer to the ECU user manual for any information concerning pins and cable 
connections. 

For straight connection of RS232/CAN 

ECU Bridge

 to the ECU, connect the free cables to 

the ECU pins. 

Usin the 

CAN

 bus connect: 

 

ECU Bridge

 white cable labelled CAN+ to the pin corresponding to ECU 

CAN+. 

 

ECU Bridge

 blue cable labelled CAN– to the pin corresponding to ECU 

CAN–. 

Using 

RS232

 line connect: 

 

ECU Bridge

 white cable labelled RS232RX to pin RS232TX of the ECU. 

 

ECU Bridge

 blue cable labelled RS232TX to pin RS232RX of the ECU. 

Refer to the documentation downloadable from AIM corporate website, “Download 

area”, “ECU Connections” for further information concerning the connection of 

ECU Bridge to the ECU.
