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

I have same problem with both ECU. Followed the instructions from help menu step by step when it calibrated.
TPS1-2,PPS1-2 inputs calibrated TPS% without ETC controller is on 5% At first time when i 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% . Ok i tought 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. My measurements: |

The NFET driving bridge output EC10/pin2 was damaged => unable to pull to GND (so output was +12V all the time).
* the NFET also had some (not very strong) coloring due to heat * since all outputs are tested before delivery (the NFET was originally good, driving the load and the "blue" indicator LED in the tester) * the only likely cause is accidental short to +12V during install (possibly without a fuse, or high current fuse) ** the FETdriver, traces, and other components seem to not have been damaged at all Symptoms were (with both ECU): * Followed the instructions from help menu step by step when it calibrated. ** TPS1-2,PPS1-2 inputs calibrated ** TPS% without ETC controller is on 5% 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.

ETC DC=0% (in Econoseal10 connector)Between Pin1 and GND = 0V, BTw Pin1 and Pin2= -12.14V, Btw Pin2 to GND=12.15V
ETC DC=100% Btw Pin1 to GND = 12.19V, Btw Pin1 to pin2=0.11V, Btw Pin2 to GND = 12.08V Maybe a wrong FET inside the Bridge because the Pin 2 voltage doesn't change? |

* ETC DC=0% (in Econoseal10 connector)Between Pin1 and GND = 0V, BTw Pin1 and Pin2= -12.14V,
** Pin2 to GND=12.15V * ETC DC=100% Btw Pin1 to GND = 12.19V, Btw Pin1 to pin2=0.11V, ** Pin2 to GND = 12.08V 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. |
