UPDATE: My hard drive crashed as I mentioned 11 or so months ago and have not been able to recover the video since. So, since I had already got the problem fixed, I couldn’t another video so I thought to post my update here. I know it's been a long while since but I wanted to update everyone that ever since I replaced the 4H/4L (did it on my own. My mechanic wouldn't dare to do it even when I offered him cash. LOL) actuator. For the 2007 Tundra, the rod is locked from the inside of the differential. Since the actuator rod itself was good, I didn't need to take it out of the differential as it would be too difficult, and because I was not (still is) an auto mechanic I didn’t want to risk more issues. To replace the actuator with the new one, I disassembled the new one entirely, removed the old one, and then carefully installed the new one. I had to carefully reseat and set the gears correctly for the 4H/4L to engage. Trials and errors all day long until I finally got it to set correctly. It was a pain but I managed. The cause was due to water getting inside the 4H and 4L box through the air hose and everything inside the actuator was corroded. A week prior, I cleaned and applied new grease but would not work still. So, the following week, I finally decided to replace it. I also traced the air hose up to the transmission and engine and I discovered that the hose was just hanging underneath the transmission widely exposed. After I replaced and tested the 4H/4L, I replaced the hose with a longer one and relocated the hose up to the engine bay. It has been a little over a year now and everything still working as is. I have done over a dozen overland, off-roading, river crossing - including off-roading in the AK Ozarks back in Feb. 2022, etc., and still, experience no issue with the 4H/4L. I, again, apologize for the lost video. Last but not least, after I did all that above, I stumbled onto this video kzbin.info/www/bejne/aHmudp-rjdyVkNE. I didn’t touch the motor or anything this video described to do because I already got the new actuator. I just replaced the old one with the new one instead. The 2007 and 2008 Tundra are very similar but I believe it is a lot easier to remove and replace the actuator without having to do what I did above on the 2008 and newer Tundra.

How I can contact you , to ask about it why my 2008 tundra 4h is blinking

[@tjxpeditionoverland5506]

First thing I would check is the wire, the ABS cables. If they are all fine, follow the shifting process and also use a good ODB II device to reset everything first. I recommend the Veepak ODB II from Amazon. If none of the mentioned failed, you might want to replace the actuator. The 08 Tundra is easy to replace it. I spent days to get my 07 to work.

Is it the Rnnner with the v8

2007 Tundra

[@monsterholics]

Did you figure this out?

[@tjxpeditionoverland5506]

I replaced my ABS sensors and harnesses. Then I reset/ cleared all error codes using this Veepeak OBD2 I got from Amazon. After I cleared the codes everything worked and has been working since. I did a video on this but my hard drive crashed so have not been able to get another video out.
