And ordered an ETC bridge controller (default: no special request)


Solved

The NFET driving bridge output EC10/pin2 was damaged => unable to pull to GND (so output was +12V all the time).

Symptoms were (with both ECU):

At first time when connected the ETC motor to the bridge(ETC DC was 0%) the TPS went up to 100%.
  • I Tried on ETC DC=100% the TPS=0%
  • thought I have to swap the ETC motor pins. I did it but when i raise the ETC DC From 0% to 100% The TB is closing not opening.

Measurements:

VBatt=12.19V

Replacing the NFET solved it, pin2 reacted as it should.

Note: preferrably use the backout plate in the econoseal connectors (normally yellow in the EC10) to prevent sliding out of receptacles.
