Apologies for not seeing this earlier and thanks for past services.

 

Could you check this vin for me please and Lend any advice on my 4x4 issue? Vin 1GNDT13S422226262 the issue is that the light on the 4 wheel switch is on but 4 hi doesn't work, a4wheel works fine and I think from what I can tell so does 4low. I can here the actuator working when I switch between all settings. I had a mechanic look at it and he can't figure it out he said there no codes and all appears to be working fine he said he's never seen anything like it . I've read some things about the atcm going to sleep and needing to be replaced is this a possible cause
