Is there something that would disable vehicle while driving

scan vehicle for trouble code vehicle shutting down due to a possible problem with your awd being disabled

limp home feature be disabled ????? It's not a feature as you put it . Vehicle has a problem , have the DTC'S check have the problem fixed , then it won't be in limp home mode , Probably something wrong with the transmission

I don't think you can disable all wheel drive. All 4 wheels work in harmony to drive the vehicle. Lift one wheel off the ground and try to drive, It will not move.

AWD Disable indicator
The AWD Disable indicator is located in the instrument panel cluster. This lamp is used to inform the driver that the AWD system has been disabled and no torque will be applied to the rear wheels during a slip condition. The AWD Disable indicator is controlled by the powertrain control module via a class 2 message.
Powertrain Control Module
The powertrain control module monitors the data from the ABS controller and Rear Drive Module (RDM) for proper operating conditions. If inappropriate conditions are present the PCM commands the differential clutch pump actuator check valve closed, disabling the AWD system. The PCM also commands the AWD Disable indicator on.
Is the All-Wheel Drive Disabled Indicator Always On ?

It just said starting disabled , nothing else ?
Starting Disabled (Due To Electronic Throttle Control)
Starting Disabled (Due To Theft System)

Reduced Engine Power message ?

If this is the Air Bag fault light, then have your vehicle checked out and repaired for a failure in the airbag system. Your air bags may not deploy in an accident if you don't get it fixed. When you start your vehicle, the computer checks for the presence of an undeployed airbag. If it doesn't see an airbag it will turn on the light. This could be something as simple as a poor connection. If your planning on driving your can after an airbag deployment, this may be a legal issue, depending on where you live. Legal issues would also apply if your trying to sell a rebuilt auto, without airbags.

If this is an All wheel drive vehicle verify the location of the noise. It could be many things. One possability is the universal joints on the axles. I had a ford tempo awd that got pretty noisy. Mine were on the rear.

it is illegal to do this also the vehicle will not pass its annual mechanical inspection and then if your stopped whilst driving then you are driving a defective vehicle and you face a big fine and a driving ban

The center pully is the IDLER PULLEY.
It is also referred to as the TENSIONER.

It has a coiled spring that creates the belt tension. Replace it ($15) (and the belt) ($8).

Hope this helps!

It sounds like sensor issue in the controls.
