I believe if the temps are too high it will also give you an error. Should be at normal operating temp.I changed touchpoints with no problem, but when trying to do relearn on the TCM it gave the engine temp warning. The engine/ tranny fluid was well over 80 deg. and after a few min. I received a fatal error....Any ideas???
What year is your GT-R?I will point Joe to this thread.
Which TCM are you running? LC1, LC2, LC3, or LC4? Also what is the firmware on your AccessPORT? To find this on your AccessPORT go to "AccessPORT->About" and look for the firmware.I tried at 60C's and at 80C's, the on screen prompt instructed to do it at Engine Temp 80C's.
Do you have a recommended temp range for the trans ?
That is what I have also observed. Make sure to start the car first before you push the button on the AP for gear learning. If you don't have the car already running it will fatal error every time.My car has to be on to do the relearn. If it is not, the AP will say "start engine" and when i do, it will freeze for a few and then say fatal error.
I unplug it and start the car first, then do the relearn and it works perfectly. Tried it twice now and it works without issue.
Something to try if you haven't.
What firmware do you have on your AccessPORT?Still fatal error here even with started car and in 'P'.
I have the JF04A with LC5 function.
