this may be no help atall, but i had a GMC pickup once, and there is a vacuum switch that was stuck and that was causing my problem. it was around a $300 dollar fix, and that was 8 years ago, so i imagine it is quite a bit more expensive now.

Normally when I see this it almost always turns out to be the actuator on the front differential has failed. It is possible that a fuse has blown but you may want to confirm that the solenoid is not bad.

you have a vacuum system problem more than likely. The controls at the wheels are switched using vacuum motors/pumps on vehicles equipped with auto hubs.

You have a very bad COP Ignition Coil,that is spiking the PCM (computer)
The spike comes back on the TPS Sensor,then the PCM doesn't see the
throttle signal your foot sent thru, the pedal actuator (gas pedal) ,so it puts the
car into ETC Failsafe,and you can only go 6 mph.
If you got no ETC Failsafe, on the bottom right side of the dash, tell me what you do have
I need all the codes,if you have a MIL Lamp on ( the one that looks like a wrench)

P0606 indicates Control module internal performance. GM is indicating of the replacement ECM. Once replacement is completed reprogramming the ecm is necessary. Locally a few auot parts stores can reflash the ECM.May want to check with a NAPA or Carquest for this otherwise dealer is probably the only option.
Notice: Control module damage may result when the metal case contacts battery voltage. DO NOT contact the control module metal case with battery voltage when servicing a control module, using battery booster cables or when charging the vehicles battery.
Reverse process for installation
