what large topic. and wow, not even a FUNCTION STATED
just the WHOLE PCM,.
no symptoms, no issues, just that.
not sure what engine you have there, and matters !!!
most PCM's relearn EVERYTHING after you pull the battery
connections or the PCM memory fuse. IOD fuse.
dont pull the battery, or lose radio passcodes. (bricks IT or NAV bricked, if opted)
lots of learn, paths.
fuel trim? ( does o automatically as does spark)
spark advance, and knock data?
transmissions all have learn mode, and do so automatically when reset.
now the last one, some cars, the TB (throttle ) body must be relearned, some are auto learn others not.
aka: throttle by wire ,relearn.
did you replace something (my other shoe drops......)
did you first scan the PCM and see if there are issues.
if not, why not, why work blind>?
there are other learns
seat position (guessing BCM)_
pedal position relearn, omg.
Sentry Key "Customer Learn" Mode
transmission quick learn or drive learn (read the FSM yet?)
chapter 8e-290 + all those learn steps for trans, takes no tools.
instrument cluster learn mode? Odometer?
At the garage door opener receiver (motor-head unit) in the garage, locate the 9learn9 or 9smart9 button.
sun roof relearn?
"Is the voltage reading within the listed specification when the
jumper wire is installed?
Yes >> Replace the Throttle Body Assembly. Disconnect the Battery
when replacing the Throttle Body Assembly. After
installation is complete, use a scan tool and select the
ETC RELEARN function.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
No >> Go To 4
NOTE: Remove the jumper wire before continuing."
ill stop here, (i scanned the whole FSM for you on LEARN)
these newer cars the PCm .,BCM and other modules work on cooperative modes. Ill be the last to ever say , where learn data i stored, that i below my paygrade (retired and zero) LOL !
why not post something more focused.
I'm considering a new TB.
what do I need to know.?
