Check Vehicle Stability Control System

What are the causes of this warning light?

Backstory

My truck has been lifted for a while now. I recently installed some bypass shocks and some wiring that involved the underhood fuse box.

When doing the bypasses I pulled the driver side cable a bit tight. No visible damage though (I don't really want to buy a new one unless that's root cause).

I checked the fused and didn't see anything. I calibrated the vsc just in case. Light still on.

Can a missing/improperly installed fuse cause that? I'm thinking it's probably the cable but not positive. If I recall a user here ripped one of theirs and lost 4wd. My 4wd works fine.

Going to the dealer really isn't an option.

So...could it be something other than the cable?

 

So...I've checked everything. Every single fuse on the truck is fine. Every wire that deals with abs looks okay.

Next up is ordering 60 dollar abs lines and 100 dollar wheel sensors.

Or go to the dealer and pay too much.

It has a code of that matters...C1432.

 

Pulled an abs line to see what happened. Failure changed to abs fault...

 

Here's the message.

 

Did you test all of your fuses?

 

Yep. Multimeter on every single fuse in the truck. They are all good.

I really don't want to take it to the dealer and spend x hundred but I think that's my only choice.

 

Just seems like a strange coincidence you got the vsc light after rewiring everything.

Did you test the fuses by continuity or voltage? I feel like I remember seeing the vsc light on b/c of a blown fuse at work before. I would double or triple check them. Using voltage with the ignition on.

If that doesn't reveal anything I would comb through all the harnesses along the path you were working on the new wiring. A lot of the wires keep getting smaller and smaller and I have seen them break pretty easily right at the harness.

 

Also you could try resetting the bcm by pulling the d/c cut fuse and leaving it out for a couple minutes. I forget if it's labeled "short" or d/c cut on the Tacoma.

 

Yeah I feel the same way.

The only two things I can think of:

I really stretched the driver side abs line when I was pulling apart the driver side. I though that could be it. But I tried unplugging the abs line (after messaging another member) and the failure changed to abs fault. So I know it's not those now.

My switch pro required fishing a huge connector through the firewall grommet. I might have been a bit aggressive there but was still as careful as I could be. I'm pretty sure I didn't damage anything there either.

The rewiring really only involved running a pile of wires to the rear and clipping one from the front. I didn't really touch the factory stuff.

For the stock fuses I ohm'd out every single fuse to make sure none were popped. Inside and undehood. The only one I found was the heated mirror fuse was blown. I haven't checked a schematic to see how that could be related or not.

 

Ok so here's what's getting me hung up now. How did the heated mirror fuse get blown? It is in no way related to the vsc.

When you went through the firewall did you run all your wires through the grommet for the main harness? If so, what did you use to snake it through?

I have seen cars come in to the shop that had a few wires get broken right in the main harness grommet because the owner tried getting a power wire through using a flat blade screw driver. Had to replace the entire harness.

Also, when checking fuses I've found that testing voltage with the ignition on is the only reliable way to test them. Sometimes a partially blown fuse will "look" ok when using continuity. And some of the fuses will only test as blown if the ignition is on. I've gone through both fuse boxes multiple times before looking for a popped fuse with the ignition off. Only to find it was one of the first fuses I tested once the ignition was on.

 

That's good to know. I'll try again on testing the fuses with power and see how that goes.

Initially I tried cutting through the main grommet with a knife on the inside part but then swapped to closed scissors for the second layer. At first I was trying to hack a hole for the switch pro connector. But gave up and just ran one wire through for ignition.

I guess I need to recheck to make sure I didn't damage anything and also check voltage on all of the fuses.

I sure love modern cars.

 

Oh and I have zero clue how that mirror fuse blew. I didn't touch that one.

 

Pulled ever single fuse out and manually inspected them. All good. Every connector I could see I made sure was plugged in.

Felt around the harness where it goes through the firewall and it felt fine. When I probed through with a screw driver I went on the outer part of the grommet. So I'm pretty sure I didn't damage that either.

Next up looking through the wiring diagrams to see where the vsc stuff goes and also where the heated mirror stuff goes.

 

Assuming you’re using Techstream why can’t you post the plain english description of the code you’re getting? I’m sure that obviates any problem you’re having...

 

Did you get this fixed. Lifted my 16 Tacoma last night and had the same warning light com on.

 

Where do I find these fuses?

 

Have you done the VSC calibration? OP's might be pooched because he was fishing wires...

ECU-IG No. 3, 7.5A, driver's side junction box
ECU-B No. 2, 10A, engine bay junction box

 

Both fuses are good

 

No I haven’t done the calibration since the lift. How do I do that
