2006 chevy tahoe reduced engine power message and traction stability disabled message. no engine power

Your vehicle has electric power steering !
The Electric Power Steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the power steering control module (PSCM), torque sensor, power steering motor rotational sensor, power steering motor, discrete battery voltage supply circuit, and the GMLAN serial data circuit to perform the system functions. The PSCM and power steering motor are each serviced separately from the steering column assembly. However, the motor rotational sensor is serviced as part of the power steering motor, and the torque sensor is serviced as part of the steering column assembly. The PSCM also monitors vehicle speed from the engine control module (ECM) via the GMLAN serial data circuit. At low speeds more assist is provided for easy turning during parking maneuvers. At higher speeds less assist is provided for improved road feel and directional stability.
Stability System Indicator The IPC illuminates the stability system caution indicator when one or more of the following conditions exists. The EBCM sets any one of many VSES-disabling DTCs. The EBCM sends a serial data message to the IPC requesting illumination.
Traction Control System Indicator
TRAC OFF The instrument panel cluster (IPC) illuminates the TRAC OFF indicator when the following occurs:
?€¢
The electronic brake control module (EBCM) inhibits the traction control system due to a malfunction in the traction control system. The IPC receives a serial data message from the EBCM requesting illumination.

?€¢
The Body Control module (BCM) detects that the traction control switch has been pressed (signal circuit is low). The Body Control module (BCM) sends a serial data message to the EBCM in order to disable traction control. The IPC receives a serial data message from the EBCM requesting illumination. The BCM sends a serial data message to the radio in order to activate an audible warning.

Your best bet is to take it to a ASE certified an qualified repair shop ,that has the diagnostic tool to fix this problem .

I have a 2008 Tahoe that had a similar error stabilization off, ABS errors, entire vehicle shutting off, door locks open/close at will, I changed out the Body control module and the programmer showed me the many communication errors from various modules, then one solution was suggested to change the Battery cable, so I started checking out the grounds and I found varying resistance from the Neg. Battery post to the Body so I removed the neg. cable to the engine and replaced the post with a threaded post connector and a 42 inch cable then added a 12inch to the frame, then also added a 12inch from the Neg. post to the body just under the Mega fuse, Make sure the paint is removed before you assemble and use the appropriate amount of washers to make the mega housing even to the body. No more errors, it was just a real bad ground and GM knows about this and it seems they are using this to make a lot of money off there unsuspecting customers,

there having a lot of electrical issues with this vehicle.i would check the eng control module and the accelerator pedal sensor for corrosion in the connectors,if there corroded clean them with a soft brush and put dielectric grease on the connectors and modules.hope this helps.

Start with testing the ABS system. Sounds like a wheel sensor is giving out bad signals. The vehicle is no longer under warranty?

It means the traction control system has been disabled. It can be done manually by pressing the switch on the dash or by an onboard computer (meaning there is a problem). If you can't press the button to get the light off, then get it scanned. Traction control system works with the anti-lock braking system and the engine to help the driver control the vehicle in the event it should be slipping or skidding. It will activate the anti-lock brakes, help reduce steering pressure to better steer and can sometimes cut out engine cylinders to reduce the power going to the wheels to better control in the skid.

Hello and welcome. the engine reduce power waraning is the key to the other problems. this is normally a problem with the electronic throttle system. the engine control module disables the traction control system when it detects a engine problem, in your case a problem with the electronic throttle system. you shouldnt drive with this concern. this is normally covered under the vehicles 100,000 mile warranty. you need to conteact your nearest dealer for help

the post that everybody refuse to read or acknowledge is the first simple instruction
when ever there is a problem , have the fault codes read first
it is free at autozone and other parts shops
then knowing what the problem is you can have it fixed at an accredited service center for less money that fixing what is not faulty costs

how do you fix the "reduced engine power" light on the dash bard of a 07 Chevy Impala LTZ and "Service Traction Control"?

traction cotrol problem take it to the dealer
