How do you change out 4 wheel drive switch on 2004 Yukon


Before trying to replace the switch ,are any lights flashing ? 2hi , 4lo, 4hi etc... Do you know which transfer case yours has ?
Transfer Case - BW 4482-NR4
Transfer Case - NVG 246-NP8
How many buttons ?
The BW 4482 transfer case features a 3-button shift control switch located on the instrument panel.
The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel
Before you replace the switch and finding out that it isn't the problem . The switch is a low voltage input to the tansfer case shift control module (A COMPUTER ) Could have diagnostic trouble codes stored .
DTC B0790
DTC B2725
DTC C0306
DTC C0327
DTC C0329
DTC C0359
DTC C0550
Auto part stores can not read these codes .

The BW 4482 transfer case features a 3-button shift control switch located on the instrument panel. When the vehicle has the ignition key in the RUN position, the transfer case shift control module starts monitoring the transfer case shift control switch to determine if the driver desires a new mode/range position. At a single press of the transfer case shift control switch, the lamp of the new desired position will begin flashing to inform the driver that the transfer case shift control module has received the request for a new mode/range position. The lamp will continue to flash until all shifting criteria have been met and the new mode/range position has been reached, or has been engaged. Once the new mode/range position is fully active, the switch indicator lamp for the new position will remain ON constantly. In addition, the switch includes a VSES request button which sends a voltage signal to the transfer case shift control module. The transfer case shift control module in turn sends a request via the class 2 data bus to the ABS control module which controls the VSES system.

The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel. When the ignition key is in the RUN position, the transfer case shift control module monitors the transfer case shift control switch to determine if the driver desires a new mode/range position. At a single press of the transfer case shift control switch, the lamp of the new desired position will begin flashing to inform the driver that the transfer case shift control module has received the request for a new mode/range position. The lamp will continue to flash until all shifting criteria has been met and the new mode/range position has been reached, or has been engaged. Once the new mode/range position is fully active, the switch indicator lamp for the new position will remain ON constantly.
DTC B2725
Circuit Description
The range/mode switch circuit consists of 5 modes. The transfer case shift control module supplies 5 volts to the switch through the 5 volt reference circuit. The current travel through the resistor of the currently active mode. The current is then returned to the transfer case shift control module through the switch signal circuit.
The transfer case shift control module constantly monitors this signal voltage to determine the condition of the mode switch circuit.
When each of the modes are selected they complete a circuit through their own specific resistor. The transfer case shift control module continuously monitors the switch input to determine whether the Neutral, AWD, 2HI, 4HI, or 4LO mode was selected by the driver.

You may want to take this to a repair shop .

Trying to get oxysens htr mon and catalyst mon to reset


Do you have a Scan tool to plug in to the cars CPU . You must reset from this scan tool and did you change the O2 Sensor with the battery hooked up. Try and take the Negative battery post wire off and wait for about 15 min then hook it up this might clear the CPU but the Scan Tool is the way to go because something else might be causing that light to stay on . Look for other issues you might have changed your sensors for no reason and make sure your gas cap is on and on right . Sounds like you need to rescan to check for other problems. need more info on what is going on and what you have done . Let me know I will try to help .

JUST CURIOUS, IS THERE ANY CORRELATION BETWEEN THE CHECK ENGINE LIGHT AND THE NUETRAL SAFETY SWITCH ON A 2001 CHEVY C-1500 PU..V6 / AUTO. COULD A FAULTY SWITCH CAUSE THE CHECK ENGINE LIGHT TO STAY ON?


The computer monitors just about everything electrical on the vehicle.The part you are refering to is not a neutral safety switch , its called a mode switch,It controls what range the vehicle will crank, the reverse lights, the indicator lights in the cluster, and tells the pcm where the gear lever is so it can produce the proper solenoid commands for that range.Have you checked codes?The adjustment precedure is critcal so would recomend not just changing parts or guessing.

My low tire light came on so I went and had air and all the tires checked but now I don't know how to turn the light off. I have had the car since 2000 and it has 50,000 miles on it but could never figure...


Hello Mattingly.

Here is some information for you regarding your problem.

The Tire Inflation Monitor (TIM) system alerts the driver when the pressure changes in one of the tires. The system only detects a low pressure condition while the vehicle is being driven. Once a low tire pressure condition is detected, the system informs the driver that a low tire pressure condition exist's, whenever the ignition is ON.
The LOW TIRE message appears on the Instrument panel if the tire pressure in one tire becomes at least 82 kPa (12 psi) lower or higher than the other three tires. The message does not appear if more than one tire is low or high, or if the system is not calibrated properly. The system does not inform the driver which tire is low. To clear this message, set the tire pressures in all four tires to the proper pressures and perform the system reset procedure. Refer to Tire Inflation Monitor Reset Procedure for service procedure.
The Tire Inflation Monitor software requires approximately one half hour of straight line driving to complete the TIM autolearn. There are several speed ranges that the EBCM needs to learn the tire inflation configuration in order to have the full capability of detecting a low tire condition. The speed detection ranges are the following:

  • 24-64 km/h (15-40 mph)
  • 64-113 km/h (40-70 mph)
  • 113-145 km/h (70-90 mph)
Each speed range has 2 modes of low tire detection.

  • Monitor Mode 1
  • Monitor Mode 2 The EBCM learns the tire inflation configuration for each speed range independently. In Monitor Mode 1, the EBCM has only partially learned the tire inflation configuration for the speed range and has limited detection capability for a low tire condition. In Monitor Mode 2, the EBCM has fully learned the tire inflation configuration for the speed range and has full detection capability for a low tire condition. If the EBCM is not in Monitor Mode 1 or Monitor Mode 2, a low tire condition cannot be detected because the EBCM has not learned the tire inflation configuration of the vehicle.

To reset (calibrate) the system:
Turn the ignition switch to RUN. Then press and hold the RESET button for about five seconds. The red RESET button is located inside the instrument panel fuse block on the right side of the dash.. The LOW TIRE light will come on and flash three times and then it will turn off.
The system completes the calibration process during driving.
The system normally takes 15 to 20 minutes of driving in each of three speed ranges to "learn" tire pressures. The speed rages are 15 to 40 mph (25 to 65 km/h), 40 to 65 mph (65 to 105 km/h) and above 65 mph (105 km/h).

There you are, this should fix you up.
Keep in mind this system uses wheel speed sensors to calculate. If one of your sensors isn't working your low tire light will remain on.

Thank you for using FixYa.

The code for the: Check engine was p0128, what is the problem?


This code is triggered because your cooling system temperature is out of range for the designated time frame that the computer is monitoring it for. Check your coolant level and if the level is correct than you need to replace the thermostat. This should fix your light issue.

What cause the engine light


The computer monitors the sensors on the car. there is a range in voltage that they are susposed to run between. When they run out of the range the computer will set the light on. You need to take it to a garage or parts store and see what the computer set as a code. Let me know and we can go from there. Get the code and a description

Iat sensor voltage 5 volts not 12


Most computer systems operate with 5volt Plus or 5 volts minus. From my experience I don't see a problem. plus or minus voltage gives the computer a range for which to base its data on as a monitoring system. I am not sure what the resistance on the lat sensor is. but if it conducts any ohms at all it should be good. if it conducts nothing at all it is possibly standing open and would be bad. Hope this is helpful.

1996 chevrolet monte carlo i feel no trans slipage. yet getting p1870 01 code


Just because you cant feel in doesn't mean it isn't slipping. The computer monitors input rotation speed and output rotation speed of the transmission. If the output isn't within a certain range the computer stores this code. The only reason for this is transmission slipping and will require a rebuild.
