Question: How To Bench Test Transfer Case Motor

How do I know if my transfer case motor is bad?

Here are some of the most common signs you may encounter when you have a bad transfer case: Gear Shifting Issues. Difficulty Staying in 4WD. 4WD Will Not Engage/Disengage. Puddle Formation Directly Under the Transfer Case’s Location. Weird Grinding, Growling or Humming Noises. 4WD Warning Light Illuminates. 4WD Transfer Case.

How do you test a transfer case control module?

You have to perform a TCCM self-test to determine whether you need to change this component or not. Turn the ignition switch while observing the transfer case shift control switch indicators. A functioning TCCM will flash all the indicators before returning to the current gear.

Can you fix a transfer case motor?

But the good news is, a transfer case shift motor isn’t terribly expensive and is fairly easy to replace. Total cost is only a few hundred dollars as opposed to the thousands of dollars it costs to crack open a 4WD system to do heavy duty internal repairs.

How do I know if my transfer case control module is bad?

Symptoms Of A Bad Transfer Case Control Module Gear Shifting Issues. A major sign of a bad transfer case control module is having problems shifting between the two gear rangers. Difficulty Staying In 4WD. 4WD Will Not Engage/Disengage. Puddle Formation Under The Transfer Case’s Location.

Can you drive without a transfer case motor?

Without a transfer case, you will not be able to drive the vehicle since the power is split 50/50 to the front and rear drive shafts and in 4WD or 4H mode. Hence, without a transfer case, a traditional 4WD vehicle cannot drive.

How does a transfer case encoder motor work?

The encoder motor is what provides the power for your vehicle to switch back and forth between two-wheel and four-wheel drive modes. Most transfer cases with shifters require the vehicle to be in neutral while switching between the two drive modes. This is necessary to prevent gear binding.

What does a transfer case control module do?

Transfer Case Control Module (TCCM) is the brain behind the electronically shifted 4WD systems. The TCCM processes the shift request from the dash mounted mode selector buttons, executes the shift, and verifies the shift was completed. Replace your current failing or faulty item with this direct replacement.

Can you test a transfer case motor?

Test the transfer case motor with a test light (Ohm preferably): locate the yellow and orange wire on the actuator because that controls the motor. These two wires go into the motor itself. Set the Ohm to 200 ohms. Then, place the probes on the orange and yellow wires.

How do I reset my 4×4 control module?

Cheap way – To clear the codes and reset the computer, pull the 5 amp TCCM fuse, located at the bottom of the fuse box. Wait at least a half hour, and then replace the fuse. Turn the ignition key to run, wait for the 4×4 lights to blink, and then turn off. Repeat 5 times, and then start the truck.

How do I know if my 4×4 actuator is bad?

You will know your 4WD actuator is bad when the 4WD (either 4H or 4L) becomes difficult to engage, gets stuck, or fails to activate. Any of these symptoms means that your actuator is faulty and it should be checked immediately.

What happens when a transfer case fails?

When your transfer case goes bad, your car might jump in and out of 4-wheel drive on its own. This indicates an inability to stay in a drive mode which can damage the transfer case, other systems on the vehicle, or cause an unsafe driving situation.

What happens if transfer case is low on fluid?

Difficulty changing gears – Low or dirty transfer case fluid can affect your transmission’s ability to shift gears. It can also result in your car unexpectedly falling out of four-wheel drive. This will create loud grinding noises which may become louder when four-wheel drive is engaged.

Does a transfer case do anything in 2wd?

In 2WD mode, the transfer case does not send power to the front driveshaft.

Can you drive with a blown transfer case?

Should you drive your car with a bad transfer case? Driving your car with a bad transfer case is a bad idea. If you continue to drive with a transfer case that has a serious mechanical problem, you could destroy it beyond the point of repair, and possibly damage your transmission, driveshafts and axles in the process.

Can I disconnect my transfer case?

You can unplug the fuses, unplug the t-case, or unplug the control module. All would have the same effect. Unplugging your fuses is the easiest solution. If you unplug your t-case, you will have a wire left hanging, and if it ever snags on anything and rips out, it will be a pain to get that fixed.

Where is transfer case Control Module?

The transfer case control module (TCCM) is the part that controls the general operation of the 4-wheel drive system. Its activities include request processing, execution, and verification of system performance. Usually, the TCCM is located in the control panel on the steering column at the driver’s position.

How do you put an encoder motor in neutral?

Turn the key to the on position, shift the truck into neutral and push the button for the original gear you were in (in my case 2 Hi). This will shift the motor into the correct position for your TC shaft and you can install it.

Where is the transfer case actuator located?

TRANSFER CASE ACTUATOR They are located on the outside of the four-wheel drive transfer case housing.
