"How to Reset a VSC Light on a Highlander

The Toyota Highlander is a midsize sport utility vehicle that features all-wheel-drive, an automatic transmission, third-row seating in several creature comfort options. Standard safety options include a tire pressure monitoring system, air bags and a vehicle stability control system. Certain vehicle malfunctions may impede the vehicle stability control system, causing the "VSC" light to appear on the dashboard. Resetting the VSC warning light that appears on your vehicle's dashboard may be possible by performing a simple repair.

Step 1
Shut off the vehicle's engine and apply the parking brake to protect yourself while working on the vehicle.

Step 2
Open the vehicle's hood and examine the engine compartment. Locate the air filter box mounted to the left of the engine. The air filter box features a black exterior, square in shape, and a large ribbed intake hose.

Step 3
Check all of the small black vacuum lines surrounding the air filter box. Reconnect any disconnected or loose vacuum lines you find.

Step 4
Start the engine and drive the vehicle to clear the "VSC" warning light displayed on the dashboard. If the VSC light fails to go out after driving the vehicle normally, proceed to the next step.

Park the vehicle, turn off the engine and set the parking brake. Open the vehicle's hood and disconnect the battery's negative cable for 15 seconds, using an appropriate size socket. Disconnecting the negative battery cable will reset the vehicle's computer and clear the "VSC" warning.

Items you will need
Ratchet and socket set."

 

Thanks for.your advise, had done it couple times but it vsc and check engine light will be on after 20 minute drive.

 

You need to check the ecu to see what code is causing the check engine light and address that.

 

Took it to the shop today, according to the mechanic its the camshaft position sensor that is faulty.

 

double check to make sure that sensor was plugged back in after the timing belt replacement.

 

Thanks!

 

We get the same thing on our 01 from time to time. Shows up as an issue in the EVAP system. Not sure what it is, so I just reset it every couple weeks

 

Went to a shop and used their code reader and was pointing to a defective camshaft position sensor. I just replaced the said sensor today but still the check engine and vsc is on. I dont know now could it be the up stream oxygen sensor?

 

Did you reset the CEL?

 

What is the proper way of resetting CEL?

 

Let’s take a step back. What was the code? There is a sensor on the back of each head. Which side did you replace? The crank sensor can also affect the cam signal. How did you know which sensor to replace?
You apparently want to do your own work, so I recommend getting a Bluetooth scanner so you don’t need someone else to read codes for you. I like the OBDLink Mx+ for these Gen 1 Highlanders. It has optional extended diagnostics available and can read and plot many PID parameters at about one point per second, which is useful for troubleshooting in many cases.

 

Ok.thanks!

 

Proper way of resetting the check engine light is with a code reader or scanner.
But you can do it by disconnecting the battery for about 15 minutes. Problem is that you lose stored information for the radio, sun roof, engine trims etc so it takes a while to recover from disconnecting the battery.

What else would cause the VSC light to be on. I had battery disconnected for a good half hour cleaning the battery posts and replacing the terminal bolts and nuts. No DTC

 

Many. Any detected problems with the engine and driveline will turn off VSC and turn on the VSC warning light because the module is not sure it can control the engine, transmission, and brakes to the program.
What are you using to read codes? Many times when people say there are no codes it is because their scanner does not have the software to read all modules. Most inexpensive scanners will not read the ABS and VSC codes on these Gen1 HLs. OBDLINK MX+ And OBD Fusion have an extra package that will.

 

I have OBD Fusion. I bought the $9.99 package a month ago. Felt it does a great job detecting codes. There is another package for $44 but was skeptical because age of vehicle. I went into self tutorial mode and to my astonishment found enhanced networks particularly ABS/VSC/TRAC (unreal). Anyhow, I found the code C1336. Using the ts and cg reset method the light is off. You guys definitely know your stuff when comes to these vehicles. Much appreciated

 

What is the ts and cg reset method? I have a vsc light on after swapping out my battery a few times

 

You bring up a great point for others. I should have added that with OBDLINK MX+ and OBD Fusion you need to connect to the enhanced manufacturers networks to access the enhanced diagnostics. The generic OBD2 network doesn’t access all the modules, and unfortunately they don’t make it very intuitive. It requires reading the directions or spending a lot of time going through the menus.

 

Yes, reason I mention going into self tutorial mode. Went online and found Getting started with OBD Fusion. It explains what I took for granted
