How may buttons for the 4X4 two , three , or four ? Do the lights flash ? Any messages - service four wheel drive system ? Which transfer case does it have ?

Transfer Case - NVG 246-NP8 (Two Speed Automatic)
The transfer case shift control module uses the VIN information for calculations that are required for the different calibrations used based on axle ratio, transmission, tire size, and engine. The system does not know which calibration to use without this information.
Transfer Case Encoder Motor
The transfer case encoder motor consists of a permanent magnet (PM) DC motor and gear reduction assembly. It is located on the left hand side (drivers side) of the transfer case. When activated it turns the sector shaft of the transfer case (clockwise or counter clockwise) to shift the transfer case. The encoder motor is controlled with a pulse width modulated (PWM) circuit within the transfer case shift control module. This circuit consists of a driver on both the Motor Feed A and Motor Feed B circuits. The encoder motor is bi-directional to allow the motor to shift the transfer case from 2HI or 4HI to NEUTRAL and 4LO positions.
Transfer Case Encoder
The encoder is mounted to the transfer case encoder motor assembly and is replaced as an assembly. The encoder converts the sector shaft position (representing a mode or range) into electrical signals inputs to the transfer case shift control module. The module can detect what position the transfer case is in by monitoring the 4 encoder channels (P, A, B, and C). These inputs translates into AUTO 4WD, 2H, 4H, NEUTRAL, and 4L or in transition between gears.
Transfer Case Motor Lock
The transfer case motor lock is used to provide a 2H, 4H, and 4L lock-up feature. When the lock circuit is energized, the transfer case encoder motor is allowed to turn. When the transfer case is placed 2H, 4H, or 4L the motor lock circuit has no power provided to it and the lock is applied. This assures that the transfer case remains in the current gear position. When AUTO 4WD is selected the motor lock remains applied until an adaptive mode (torque is applied to the front propshaft) is required. During an adaptive mode the motor lock circuit is energized and the motor lock is released, enabling the encoder motor to turn and apply torque to the front propshaft.


SERVICE indicator (4WD/AWD) Lamp
The SERVICE indicator (4WD/AWD) lamp is an integral part of the cluster and cannot be serviced separately. This lamp is used to inform the driver of the vehicle of malfunctions within the automatic transfer case (ATC) system. The SERVICE indicator (4WD/AWD) lamp is controlled by the transfer case shift control module via a Class 2 message or by a Sevice Indicator Control Circuit.

The first thing to do before assuming it's a loose wire would be to have it checked for codes , auto zone , advance etc... can not check this codes .
DTC B0768 Service Indicator Circuit High
DTC B2725 ATC Mode Switch Circuit Malfunction
DTC C0300 Rear Speed Sensor Malfunction
DTC C0305 Front Speed Sensor Malfunction
DTC C0308 Motor A/B Circuit Low
DTC C0309 Motor A/B Circuit High
DTC C0310 Motor A/B Circuit Open
DTC C0315 Motor Ground Circuit Open
DTC C0323 T-Case Lock Circuit Low
DTC C0324 T-Case Lock Circuit High
DTC C0327 Encoder Circuit Malfunction
DTC C0357 Park Switch Circuit High
DTC C0362 4LO Discrete Output Circuit High
DTC C0367 Front Axle Control Circuit High
DTC C0374 General System Malfunction
DTC C0376 Front/Rear Shaft Speed Mismatch
DTC C0387 Unable to Perform Shift
DTC C0550 ECU Malfunction
DTC C0611 VIN Information Error

If you know nothing about this , your best bet would be to take it to a qualified repair shop .

Hello jaygm77,

The brake light switch is connected to the brake pedal, see image below circled in red.netvan_211.png

I hope this helps.

Regards,

Jerry

If the circuit has power and the fuse is good the problem is most likely the switch. Look under the dash above the brake pedal arm. There is a small plunger type switch which is activated when the brake pedal is depressed. Sometimes this switch gets loose and or out of adjustment. There are two nuts on the shaft (one on each side of the mount). They should be adjusted so the brake lights activate when the brake pedal is depressed about 1/2 inch. If adjustment does not activate the lights use a multimeter and see if the switch is good by touching each of the two wires and depressing and releasing the switch. If there is no difference replace the switch.

po134 is o2 sensor bank 1 sensor 1
po161 another o2 sensor
p1345 crankshaft position sensor
possible cause for o2 are vehicle control module (PCM) or wiring

The problem is the starter is not meshing with the flywheel properly or the gear on the starter is stripped or the flywheel gear is stripped. You will have to remove the starter and then check the flywheel gear they should be sharp looking if they look sort of rounded then you have to replace the flywheel. If the flywheel is OK then check the gear on the starter and the same rule applies (Sharp or Rounded ) If this is OK then the Starter is not position to the flywheel properly so you must adjust it by shimming it. Sometimes you have to replace the starter because the starter has been lose and the holes for the bolts have widened and there is to much play.

Make sure that there are no lights or components running in your vehicle when it is shut off. If your battery is loosing power when it is off then it is a shot battery and you need a new one. if the battery is going dead when you drive then you have a bad alternator. good luck

You don't. What repair are you trying to accomplish? If it is merely a "tune up", timing is not necessary.

they are very very tight,,,beet them out!

2000 GMC Denali | Answered on Aug 08, 2010


ok,you will need to hook up a battery charger to it.turn the key on and leave it on for 10 minutes,turn it off for no longer than a minute,turn it back on for 10 minutes,then turn it off for no longer than a minute,then turn it on for ten minutes then turn it off,then it should start.somehow you lost your pragram in the key.this will take 30 minutes or so,thats why you need the battery charger,dont try to start it between cycles or you will have to start over again

The tank sending unit has a contact arm that slides over a resistance coil of wire.
When a range stops working, either the wire in the coil broke, or the arm is not making contact.
You can bend the arm, but a broken coil needs replacement. Although I have wound my own when desperate.
