Maintenance light on & 4LO flashing ?

2014 Sequoia SR5 w/ 67K mi

Maintenance light on & 4LO flashing

won't go into 4wd

no other issues I can sense, likely going to shop for diagnostics in next few days

any ideas?

 

No CEL? This might help. Says just 4 Lo flashing is MAF sensor.

 

the maintenance light is on (not blinking) is this the CEL?

 

No. Maintenance light is for oil changes and is set to come on at predetermined mileage, like every 5k. Are you sure it’s the maintenance light and not a CEL?

If it’s a CEL, get someone to read it and figure out the code. Auto parts stores will usually read them for free.

 

Sweet chart, thanks.

The maintenance light next to the oil icon is illuminated (not blinking).

This morn the 4lo light is not flashing and the Sequoia will go into 4x4?

Yesterday I swapped for a set of hwy wheels/tires, perhaps this triggered something?

 

nothing showed on scan.. appears to have resolved

 

That’s definitely what triggered it, get ready for vsc traction control light to come on next smh

 

SMH?

 

You’re going to be fine,it won’t effect the way your truck drives.there is a video on you tube on how to chemie the yawrate senior in case you get the vsc light.that should fix that problem
