4WD - Both Green and Orange Light Flashes

I'd replaced the front transfer case actuator (ADD) for my '03 due to the 4x4 was not engaging. Now everything works perfectly (2H, 4H, 4L) but the lights are still flashing. I'd inspected all the wires, and they're all looked fine. I also disconnected the battery, drove it for a while hoping it would reset and syncing with the ECU but it's not working. Is there anything else I could try? Thank you.

 

Can you read your OBD2 to see if you have any codes? Perhaps you need a re-calibrated yaw-control/traction control?

 

There's no CEL on the dash. I just plugged in the scanner and there's no codes. Can you give me instructions or link for the recalibration? I thought recalibration yaw-control/traction control is related to ABS sensor problem.

Typically yes on ABS symptoms, but I'm just spit-balling ideas as the cheapest and easiest to try first...I hope it works!

 

Hi, I tried re-calibration but still does not work.

 

Daaaaang!

If you need any others, let me know which ones and I'll pull them.

If you know somewhere I can upload a zip of entire manual without sign up and all that crap, lmk. It's one html file, one image file, and rest are pdf files. There are over 1000 PDF files.

 

Thank you but I don't have any issue the stability controls. Only 4x4 lights are on eventhough the ADD was replaced but everything works.
