Title: Renault Scenic ECU
Post by: ecudev on April 23, 2008,05:27:41

Hi
I have this ECU:
Bosch 0281010819 from Renault Scenic 1.9 DCi
I would like to find the pin out for this.
The ECU has 3 connector "blocks" marked as:

Block1:
Columns H-A (left to right), Rows 4-1 (top to bottom)
Block2:
Columns A-M (left to right), Rows 1-4 (top to bottom)
Block3:
Columns A-M (left to right), Rows 1-4 (top to bottom)

I only need to find power (12V battery and ignition), ground and diagnostic (K/L line) connections as a minimum.

Thanks
Ecudev

This ECU is from  a renault senic RX4?  Engine code F9Q 746?

This ECU has no K and L line, it is CAN based diagnostics.  CAN high is plug A pins 4a and 4b.  CAN low is plug A pin 4a.  On plug A pins 3c and 3d are also for diagnostics.

Earth is Plug B pins 3l 4l 4m.

Ignition is plug B pin 3e.

There is no direct +12v connection, it is only via engine control relay.
