One customer wonders if it’s possible to read that ecu since its KT200 can’t read it. Valeo VD46.
Answer:
VD46 is different from V46, the processor is SH725 and no driver supports.
Difference between VD46 and V46:
1.VD46 has only two compartments while V46 has 3.
2.V46 is with SH72544 processor, VD46 is with SH72546
Other Solutions:
Try JTAG mode with Trasdata Tool.
PCB:
Direct Connection:
For the connection use the cable F32GN037C/D connected to the ECU.
Make sure that the POWER led (red) on Trasdata is ON.
ECU Connector:
JTAG Loose Wires Connection:
For the reading & writing procedures use the FLAT cable F34NTF53
Connect the wires on the pads avoiding any short circuits.
Connections are required on both sides of the ECU.
1)Processor Side
2)Cover Side
Review:
VD46 will not support due to SH72546R processor. I use Trasdata 11
