Hi all,
long story short - I have replaced the standard steering wheel on my 2011 Explorer Limited (with Selectshift) with one that has paddle shifters. I do not like how the manual shifting works on the Limited trim - put it in the Manual Mode and the then use the plus/minus button on the floor shifter to up or downshift. The Sport trims (Edge, Explorer etc.) have the possibility to use paddle shifters in the Drive mode - when you use them you get sort of temporary manual control and can up or downshift.
After reviewing the wiring diagrams I connected the steering wheel paddle shifters to the matching wires running from the floor shifter to the PCM. I confirmed the functionality of the paddle shifters in the Manual mode and they work properly. However they do not work properly in the Drive mode, despite the fact they do connect the appropriate pins of PCM when engaged. In other words the Control Return (C-SIGRTN pin 56) and Shift UP (SSTU pin 23) or Shift DOWN (SSTD pin 24) are connected on the PCM.
It appears that there is some sort of programming or settings involved with how the PCM reacts to the input signal, depending on if it is a Sport trim or not. I would like to enable the ability to shift in the Drive mode, but have not found any info on which settings are involved with this feature.
If any further details, diagrams or pics are required, I can provide.
Many thanks in advance.
