shrug... you are the "Master"

A 2second wiggle isn't that hard

 

Thanks Sandman. I used probes with my multimeter.. very carefully. Mr. Master is what we call in my former profession an a$$clown.

 

"Adaptions" are kept alive by the battery and reset when the power is cut. Both base idle adaptions and fuel trim are set to 0 or no change. The engine wont run off the "adaptions" if a fault is detected in the upstream o2 system. The truck runs open loop with no trim on the factory map. The system is so good, if you have bad 02 and no MAF. it will run ALPHA-n using only cylinder fill calculations from the TPS and programmed cylinder size.

It's not rocket surgery, maybe he pinched a wire while he was beating the sleeve back into the block? It didn't have the code before, so what changed?

 

Adaptive settings are not simply reset upon just a battery disconnect, but nice idea. It's the same as the SLABS Unit at storing hard faults (They do not clear with just battery disconnect). So you can disconnect the battery, and wait until the next lunar eclipse, but the Adaptive settings for the Engine/Transmission will not simply reset.

 

WTF are adaptive settings? You're making **** up now. If you disconnect the battery it clears what you call "adaptions" which is saved fuel trim data/idle data/readiness tests/Mode 6 stuff like misfire counts on previous drive cycle.

 

For something I made up, I sure wonder why the T4/VCM, Hawkeye, SnapOn, Lynx, and the Nanocom have a "Reset Adaptive Settings" Option

 

There is no such animal called "adaptive settings" There's a button on my machines to clear adaptions also. But it doesn't do anything more than removing the battery cable for 5 mins. There are no settings, nothing is set or chosen, the ECM just forgets what it has learned and starts over.

 

Still not how it works, or people would just be disconnecting batteries for all trouble codes like a 14CUX system. Bosch Motronics 5.2.1 will keep hard fault codes, or adapted values, even after the battery is disconnected. The days of the 14CUX are long gone.

 

Lol "adapted values". "That's because the ECU has "learned" from the original sensors and it "adapted" to them." ---- Uh no. The ECU reads the o2 sensor output and adds or subtracts a percentage of fuel to the base map in that cell. That is the "adaption". The computer does not learn the sensor or adapt to it. The o2 error control is triangulated from RPM/MAF. MAF error is calculated from cylinder fill, RPM/TPS/o2 Its impossible for it to "learn" a sensor, it can only determine good or no good by using hard programmed values and other sensor input. Adaptions are only adjustments to base calculations. You don't need a command to clear them, you just take the power away. They are erased when you disconnect the battery. It's EPA mandated since 1996. ANYTHING emissions related can be diagnosed and repaired with a 20 dollar scan tool since 1996. Mode6 data gives you real time and historic misfire data/long term short term trims/o2 feedback. There is literally no way on the planet to clear this unless you have vendor specific software or just disconnect the battery. The whole OBD2 system was designed that way so that any shop could fix the emissions related problems on cars. Let's say you have a bad fuel pump on a Ford 4 cylinder, it is only putting out 20PSI, the oxygen sensor reads lean because the pulsewidth of the injector has remained the same, but the pressure at the injector has gone down. The computer trims the STFT and LTFT to +25/+25 because it never sees the narrowband o2's switch to rich. So after you replace the fuel pump, you need to disconnect the battery to clear those adaptions. The car would run fine until it went into closed loop, where for a split second it would use that +25/+25 trim to expand the injector pulsewidth by 50% if it ran for long enough (maybe, Maybe not) for the o2 to respond rich, it would start to cut back the fuel on STFT. you would eventually have -25 STFT and +25 LTFT and it would give you codes again. The way to fix this is to unplug the battery and erase those adaption tables. Unless you have factory software where you can send a "clear adaptions" command. Removing the battery is the only way. From 1996 till about 2010 who had access to factory or cloned software? Pretty much no one.
