Question about 2004 Chevrolet Tahoe

2 Answers

I have a 2004 Chevy Suburban 4 wheel drive. The words "traction active" comes up on the driver's info screen. Then the forward motion stops and the vehicle drifts. It feels like the tranny is disengaging but the motor doesn't rev, it just no longer pulls the vehicle. I was not on any slippery surfaces nor off road. Been to the dealer 4 times they can't "pick up a code" on it and they don't know what to do. Thank you in advance for any info. Mary Anne

    I have the same problem. The traction assist activates on dry surfaces and, according to the dealer, does not register activation in the log. It happens frequently and I cannot get the dealer to fix the problem.

I have the same issue, 2004 Tahoe LT. 60k miles. Everything points to the wheel speed sensors. I realize this is a few years past the original question, but wanted to be sure the info is posted in FixYa. Will be working on it today, and will post findings.

Traction active message coming on in a 2003 hummer h2


Hello! This is usually the result of a wheel speed sensor issue. Most technicians look for WSS fault codes, to decide which one is failed, but if there are no fault codes, they don't know where to look. The trick, is with the scantool hooked up, watch the ABS solenoids and see which ones activate during the traction event. If the Wheel Speed Sensor is acting up, it can confuse the ABS module into thinking that wheel is slipping and it will activate the ABS pump and solenoids for that wheel, to try and slow it down.
With the stability system disabled, it won't try and slow the "slipping" wheel down, which is why it won't do it when disabled.
and the noise you hear is probably the ABS motor and solenoids, which are mounted on the Left Frame Rail, below the drivers seat (often heard at the firewall).
There was a bulletin to replace the Yaw Rate Sensor and update the ABS Software, which is probably where the $400 went, and it may have needed it, but obviously that wasn't the problem. I beleive that the issue lies withing the Wheel speed sensors.
the most common symptom of speed sensor failures is premature ABS activation, but I have in some instances see it cause Traction Control events take place as well. Here is a service bulletin for unwanted ABS activation:

My 2002 chevy impala's service traction light comes on after shifting from reverse to drive. it aslo seems to activate the anti lock brake mode at that time. it resets itself and does fine after


Check your brake sensors for debris inside the brake drum or caliper. This all depends on how your Model counts the turns on each wheel.

There are some Models which have a sensor in the axle and others which rely on the 4 individual wheel sensors.

When brake debris or rust "blinds" the sensors you get the problem you have unless it is a clearance problem with sloop in the differential.

I hope my solution is helpful.

I just bought a 2000 Nissan Frontier and I'd like to know the correct way to shift on the fly into and out of 4WD? I don't want to mess it up. Also is it ok to use 4WD if pavement is just wet or will that...


you can shift on the fly from 2 hi to 4 hi at any time as long as you are not under power or in other words on the gas. Hold at a steady speed or let up on gas pedal a little bit then shift, DO NOT shift truck when vehicle is speeding up or taking off. Also do not shift when wheels are spinning or when you are turning a corner. The same goes for shifting from 4 hi to 2 hi. ** Now to shift into 4 lo the truck should be stopped and put trans shift into nuetral then shift transfercase into 4 lo, and never exceed 25 mph in 4 lo position !!!!!!! To shift out of 4 lo and go to 4 hi or 2 hi stop vehicle and shift trans into nuetral then make your 4x4 shift then put trans into forward or reverse gear and VROOOOOM your on your way. Remember to NEVER and i mean NEVER shift into 4 lo while vehicle is moving forward or reverse as you will do serious damage to any and all parts of drive train. You should not run 4x4 at all unless you need to pull something where you need extra traction like a boat out of water,a stuck vehicle,or if roads are slippery, or muddy. also don't be alarmed as sometimes when in 4 wheel drive and you turn corners you will notice a binding or jerking motion, this is normal and if this is occurring i would recommend going back to 2 hi position. HAPPY TRAILS to you with the new toy. I only buy vehicles with 4x4 and have never owned a 2 wheel drive in my 31 yrs of driving. I love the idea that i have extra power and traction options when i need it,the only bad thing is your boss says " what do you mean you can't make it in,you have a 4 wheel drive!

Traction Active light comes on


1prettysmile,
The "traction active" light is a light that lets you know when a certain part of your Anti lock break system engages. Each tire has a sensor that detects a couple different things in the wheels. One of the sensors may be going bad and needs replaced. Any of these sensors going bad can cause those symptoms.
