4Lo Blinking, Unrelated DTC (P0504) (1 Viewer)

[encrypttie]

Hello everyone,

Here's another 4Lo blinking thread! I read some of the other ones but looks like in all cases they all have DTCs.

What I experiencing is this: 4Lo is off when I turn on the car. A couple of seconds to a couple of minutes after driving it starts blinking (no other lights, only 4Lo) and keeps on blinking until I turn off the engine. I live in Seattle area, so it's wet and cold here - in case this information is useful!

What is puzzling me is this:
1) There are no active DTCs, except for a P0504, which is Brake Switch A/B Correlation Code.
2) I can switch to 4Lo and 4Hi no problem, even if the light is blinking.

The 4Lo was constantly blinking before, I cleaned the hot spot in the actuator. Since then I am getting this strange behavior.

I appreciate your help in advance!

I figured it out. Even tho P0504 seems to be unrelated to the transfer case, it's the code that's causing 4Lo to blink!

I verified by clearing the code, and pressing the brake pedal which caused P0504 to be thrown, and the 4Lo start to blink.

Hope this helps anyone who comes across this in the future.
