If you have a Chevrolet Silverado with an automatic transmission and the 4-wheel drive won’t engage, there’s a good chance the problem is with the transfer case control module. Fortunately, this is a relatively easy fix that you can do yourself. The first thing you’ll need to do is locate the module, which is usually located on or near the transfer case.
Once you’ve found it, disconnect the battery and remove the module from its mount.
- Park your Silverado on level ground and engage the parking brake
- Locate the transfer case control module under the hood, near the firewall on the driver’s side of the vehicle
- Disconnect the negative battery cable from the terminal using a wrench
- Remove the two screws holding the module in place with a Phillips head screwdriver
- Pull out the old module and unplug it from its connector
- Insert the new module into its connector and reinstall it in its original position with two screws
- 7 Reconnect negative battery cable to terminal
Gm Tccm Relearn Procedure
If you own a GM vehicle with the Automatic Four-Wheel Drive (4WD) system, then you may be wondering what the GM TCCM Relearn Procedure is all about. Basically, this procedure helps to ensure that your 4WD system is working properly by calibrating the Transfer Case Control Module (TCCM).
Here’s a step-by-step guide on how to perform the GM TCCM Relearn Procedure:
1. First, make sure that your vehicle is parked on level ground and that the engine is turned off. 2. Next, locate the fuse box and remove the fuse for the TCCM. 3. Once the fuse has been removed, press and hold down the brake pedal while you turn on the ignition key.
Keep pressing down on the brake pedal until you hear a “click” sound coming from under the dash near where the TCCM is located. This “click” sound indicates that the relearn procedure has begun. 4. Now simply release the brake pedal and wait for approximately 30 seconds before turning off the ignition key.
This completes the relearn procedure!
How Do I Reset My Transfer Case Control Module?
If you’re having trouble with your transfer case control module, there are a few things you can do to try and reset it. First, check all the fuses and relays associated with the transfer case control module. If they’re all good, then you can try disconnecting the battery for a few minutes to see if that resets the module.
If neither of those work, then you’ll likely need to replace the module entirely.
How Do I Test a Transfer Case Control Module?
When testing a transfer case control module, the first thing you’ll need to do is connect a test light to the battery. Once you have done that, you’ll need to locate the transfer case control module. The module is usually located near the transfer case itself.
Once you have found it, you’ll need to remove the two electrical connectors from the module. With the test light still connected to the battery, touch one of the leads to each of the terminals on the connectors. If the test light illuminates, then your module is good.
If not, then it will need to be replaced.
How Do I Test My Silverado Tccm?
Assuming you are referring to the transfer case control module (TCCM) on a Chevy Silverado:
There is no easy way to test the TCCM, as it is controlled by the vehicle’s computer. However, there are a few things you can do to check if it is functioning properly.
First, make sure all the fuses related to the TCCM are intact and working. Next, check the wiring harness for any loose or damaged wires. Finally, have a professional scan the vehicle’s computer for any codes that may be related to the TCCM.
Can You Drive Without a Transfer Case Control Module?
A transfer case is a part of a four-wheel drive or all-wheel drive system found in many SUVs, trucks and some passenger cars. It is responsible for sending power from the engine to the front and rear axles. The transfer case control module is the brain of the transfer case, telling it when to engage and disengage the front and rear axles.
So, can you drive without a transfer case control module? Technically, yes – but we wouldn’t recommend it. Without the transfer case control module, your vehicle would be stuck in two-wheel drive mode (meaning only power would be sent to either the front or rear wheels – not both).
This would make driving in any sort of off-road conditions very difficult, if not impossible. So unless you never plan on taking your vehicle off-road or driving in anything other than perfect weather conditions, we suggest getting your transfer case control module replaced as soon as possible!
If you’re having trouble with your Silverado’s transfer case control module, don’t worry – you can easily reset it at home. All you need is a simple OBD-II scanner. First, find the fuse box under the hood and remove the fuse for the TCM.
Next, connect your scanner to the OBD-II port and clear any codes that may be present. Finally, replace the fuse and start the truck – your transfer case should now be working properly!
