Summary of change:
2 ECU has been ordered in the following option: 2 x ECU VEMS V3 - '''ETC BridgeOutput_Interface: 1''' - LCD connection: yes - Knock input channels: 0 - ignition driver: 4 - Hi-side PFET outputs: 0 - Flyback: HighZ-only 30V flyback - EGT input: 2 - 1-wire interface: no - mounting-style: flanged case - MAP connection: 400kPa (5/3mm pneumatic) - primary_trigger: HALL - secondary_trigger: HALL - Service: ASAP - Special requests: no - withSDcard: no ECU numbers: 14116 and 14115 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). * 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. I did it but when i raise the ETC DC From 0% to 100% The TB is closing not opening. '''Measurements:''' VBatt=12.19V * 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.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
