HELP!! 4Lo/4Hi Blinking

I have a 2015 1794 Edition that has gave me little issues until today. I got in the vehicle and my dashboard is going crazy. 4lo/4hi blinking, BSM not working, traction control light on and ABS light on. I tried unhooking the battery to see if things would reset but had no luck. Any possible solutions would be greatly appreciated.

 

Check your ABS sensors on all your wheels for damage/disconnection. Check your battery, bad battery really messes up these trucks. Lastly, check for rodent damage everywhere.

 

Are you having issues shifting?

 

I had this issue a couple years ago and it turned out to be my passenger wheel speed sensor broke. It was an easy fix.

 

Unplug your battery entirely and plug it back in in an hour - it will fix the issue or confirm you have a broken sensor (as opposed to a tripped working one)

 

Thanks for the all of the quick responses. No issues shifting, the truck still seems to be operating ok. The only other issue that makes me think possibly battery is that my command start also is not wanting to turn over. When I manually start the vehicle it has no issue at all.

 

Any check engine light? A code would go a long way diagnosing it.

Could also be a failed air pump. I’ve had it happen on other Toyotas.

 

My 2016 Tundra 4Lo 4Hi Flashing no other light at all..any help..

 

Could be a few things, are you able to switch into/drive in 4Hi and Low?

 

I took my truck into Toyota and the problem was a slice in the wiring to my front right abs sensor. The sensor was fine but the wire needed to be repaired. Good as new now

 

I can drive it normal but my 4LO 4H flashing..try disconnect battery an hrs still not working. Anything would help..

 

My bet is one of your abs sensors

 

Help, another cold week up here in Canada and I have the same issue as last year with ABS lights blinking 4Hi and 4low lights plus traction light on. Last year I took it in and sure enough it was an ABS sensor that was replaced. This morning I have all the same issues going on but now after driving it for a short distance I have the check engine light on and no speedometer reading at all. The truck seems to drive fine but just all kinds of electrical issues going on. Any help would be greatly appreciated as I can't get it in to be look at for a couple weeks. Thanks

 

Your battery may be going out. Low volts, bad cell, etc will cause all sorts of alerts and issues, which often seem completely unrelated to battery, but if those systems are not getting full and constant power, they can alert.

 

Hello everyone I’m having a similar problem I have hi and lo flashing and trac light as well and I’ve already changed the vss sensor and the rear driver side speed sensor and cleared it but still nothing has changed and I can’t go past 4th sometimes and I got these codes any ideas

 

I got 2014 tundra Mine comes in Abs/ 4hi/4lo and traction light comes on random no codes so on my truck rear speed sensor gets wet and after I clean it up lights goes away but no codes

 

New battery should help... next, you need to get underneath and ensure wired on the abs sensors aren't frayed...
