I would like to know the specification for serial nr 6110.
Simple tests (justified anyway, especially if ECU is old or paper lost).
Steps:
- make sure grounds are connected
- Save config
- disable output channels (good idea until the harness/app is known, and driven loads are verified, at least with simple Ohm measurement; eg between EC36/pin7 and EC36/23)
What would be the target application ?
How many IGBT ?
- measure voltage between EC36/29 (or any other +5V potential above GND) and ignoutput after powerup (output not active)
- 5 .. 5.5V measured => logiclevel output
- 0V measured => power IGBT output
- (if uncertain, use a 1k..10k "pullup" resistor, parallel with the DVM; the DVM otherwise has a very high input resistance, 1M .. 10M usually).
- 1k Ohm resistor in series with LED (anode connected to +5V) makes a very good bench setup.
- If uncertain, that is very good time saving to see in action: PC soundcard => trigger, eg with "m231" aka 24-1 signal (disable sectrig first), and test all outputs in question (or those planned to be used) 1 by 1.
- IGBT outputs are off by default, only light up during dwell time (or if configured as other, eg. misc2 function, and turned on by parameters or by inverting).
- Logiclevel ignouts pull to GND by default, so appear ON if tested between output and +5V (appear OFF if tested between output and GND)
VR or HALL trigger ?
Measure DC voltage, while connecting a 1k resistor between GND and
- EC36/27 primary trigger
- EC36/13 sectrig
DC voltage
- 0.5 .. 2V means strong (eg. 2k7 .. 4k7) pullup (1.35V is usual) => HALL input
- 0.1 .. 0.3V means weak (eg. 18k .. 27k) pullup (0.18 .. 0.25V is most usual) => VR input
- 0 .. 0.1V is also possible for sectrig VR
Injector type?
must assume 30V voltage flyback, High-Z injector only
- unless you know for sure that it has active flyback at this time.
- Even if it had active flyback 4 or 8 ch originally, perhaps it was removed if the history is untracked
Will look more by orderID. What city and country is it currently in ?
