Just purchased 2011 Tacoma DC 4x4. Before I drove the car off the lot there was an indicator light on which the salesman said was the 4x4 light. We cycled between 2H and 4H and the light persisted. He then instructed me to accelerate above 25mph to disengage the 4x4.
Quick jump to the end - the light wasn't 4x4 it was the Locking Diff engaged indicator.
My question: Is it possible that anything could have been damaged driving with the LD engaged on pavement and accelerating to greater than 25? Is there anything to look for?
Thanks for your help.
Welcome to TW... This very same issues and same salesman lack of knowledge promted me to post the following... see the bottom image for what happened to you (remember, if it is blinking, it isn't engaged... the rear locker only works in L4, but the light blinks anytime you push the RR Locker Button):
Recently some have posted that the truck was 'stuck' in '4WD' because the light was on or blinking... only to later learn it was just the differential lock switch pushed in! That light is below the 4WD light...
The lights are different... So, I just took some photos so we all can see. Let's go through the levels of traction activation and see what it all looks like:
Normal dial position for paved roads or where traction assistance of 4WD (four wheel drive) is not needed.
The lower switch, next to mirror controls (car with skid lines below) is the VSC OFF switch. This also activates AUTO LSD when in 2WD with a quick push. Auto LSD is traction control without the engine output regulated.
This is what comes on with AUTO LSD active. The VSC OFF light goes out above 30 mph.
If you stop the truck and hold down the VSC OFF switch for 3+ seconds, VSC and TRAC both turn off for open differential(s) in H2 or H4.
Go into H4 (4WD High Range) from 0-60 mph if you need more traction because of poor conditions or off highway needs.
This is the 4WD High Range indicator light... two differentials and 4 tires. TRAC in H4 has no engine regulation, the same as AUTO LSD in H2.
For more torque to power through deep snow or mud or to climb up or down steep grades, stop truck, put tranny into N (Neutral, not Park), and rotate dial to L4.
Low Range 4WD indicator light. VSC goes off in L4 and both differentails are open.
If your 4WD Tacoma is an '09 + Off Road TRD, you have 'Active Traction Control' (A-TRAC) that provides the 'brake-locking' of any non-traction (spinning) tires front or rear for tractor like crawling/ climbing. Gives traction control while in low range. Push this switch just once when in L4 and A-TRAC will activate when-ever needed to keep moving while in L4.
A-TRAC activated light.
As Toyota states, use only as a last resort and turn off when out of trouble.
While in L4 (for 4WD Tacomas), press the RR DIFF LOCK switch. (I engaged it twice today while stopped)
The Rear Differential Lock indicator is the x'ed rear differential image. If it doesn't engage, or if it is pressed while in H4 or H2 (for 4WD Tacomas) it will BLINK! Remember, when locked there is no differential action to allow the tires to rotate at different speeds, as needed when turning.
