Thanks to someone on another site sending some wiring schematics of the transfer case wiring, I was able to do some testing with a multi-meter and locate my problem, which turned out to be a bad wire that provides power to the encoder lock circuit. If it does not have 12 volts, check the transfer case switch and the power feed to the transfer case. Each has its own diagnostic procedures, and the best source for understanding how these systems work will always be your information system. Can anyone tell me when I am turning the transfer case shaft with a wrench, how many positions or detents should it have? Or you are a pupil, or perhaps even you who simply would like to know about 2000 Chevy Silverado Transfer Case Wiring Diagram. Unhook the electrical connector to this part and see if heater still blows fuses.
The transfer case module sends 8 volts to the switches, then monitors the return circuit to determine whether any of the switches is depressed. The transfer case lock is unable to hold during a hold test and the transfer case actuator will need to be replaced, and the motor learn procedure performed. I will call them to find out if lamp needs ground or hot. I took it back to the dealer, and the technician told me you have pin holes in the side of your case. The contact did not cite any performance issues with the vehicle. Do I wire it to a keyed power source? Searching for info concerning 2000 Chevy Silverado Transfer Case Wiring Diagram? You might be a technician who wishes to look for references or address existing problems.
I have checked continuity of transfer case control module in dash and it shows that is not the problem. Disconnect the transfer case control module connector X2 and check the circuit for an open, high resistance, short to ground, or short to voltage. This topic is a great deal of individuals searching on the net, for that reason we accumulate photos from various trusted sources and also recognize in their area. We intend to make a website valuable for many people. You'll have plenty of other places to do that on this project. Tried it with my new encoder, again motor hummed but encoder didn't run.
Scan tool support is available for this system. Chilton book doesn't show this wiring in the wiring diagrams, so I don't know where these other wires go. They told me they would clean it off and apply a layer of jb weld epoxy to it to seal it up. Do I wire it to a keyed power source? I had found the problem, but still could not explain why the system had stored code B2527. Checked my wiring harness which is a four prong ann it had one hot prong like it is suppose to.
. A harness repair was in order. It seemed like it was in 4wd at times. Just solder it inline with the wire and cover it with adhesive lined heatshrink. No help for the problem. The dash-mounted transfer case mode control is a set of normally open switches that vary the voltage supplied by the transfer case module when closed.
Switch terminal C will go to pin 85 to include an inline diode, 30 and 86 will go to keyed ignition source, and 87 will go to lamp. Jan 28, 2011 Fuse is located at the end of eh dash on drivers side and the Actuator is located at the front differential and on the passenger side. When each of the switches is depressed they will complete a circuit through their own specific resistor. We discovered from asking others that this may be a common problem in these trucks. Before I bought the module I tried to do a continuity check on the wires from the Tcase control module down to the encoder, but had limited success.
Thanks i will let you know. I have been driving around without 4wd ever since. I will call them to find out if lamp needs ground or hot. The truck was taken back to the garage when the service 4wd light was on and the mechanic turned it off and told us it was unrelated to the problem we were having. When we did this, it caused all kinds of random lights and data readings. The contact stated that there was recall o5v379000 for the service brakes, hydraulic: antilock. I could hear the encoder motor at the transfer case working, which confirmed my scan data and helped me find a diagnostic direction.
I'm sure you would not have to reflash a computer for installing a new transfer case. Ground Locations Ref 2003 , size: 800 x 600 px, source: www. Next find a big nut or bolt to put inside of it. Shortly thereafter the vehicle began to periodically self-engage into 4wd low when stopped traffic signal or stop and go traffic. I had none of these problems until i switched transfer case.
The heavy gauge black and red power wires had continuity. I don't want to replace the encoder motor if there is nothing wrong with it. The encoder lock circuit gets power from the fuse block in the engine compartment. Take a crescent wrench and remove it. I guess I am really lost on this one. I have the back tires off the ground, front drive shaft is out, tranny in neutral, I can spin the rear drive shaft and make sure there isn't any pressure on anything. I located the problem within minutes.
