Last Updated on January 2, 2024 by Jaxon Mike

Traxxas TSM (TQi Traxxas Stability Management) is an impressive technological innovation that has truly elevated the radio-controlled hobby. This electronic stability control system helps provide straight-line stability and smooth cornering for Traxxas RC models equipped with TSM.

However, there may be times when TSM doesn’t seem to be working properly on your Traxxas vehicle.

The steering may feel loose, the car might fishtail around corners, or TSM corrections seem delayed. Don’t panic! In most cases, some basic troubleshooting and maintenance can get your TSM system back up and running optimally.

What is TSM?

Before we dig into why TSM may stop working and how to fix it, let’s quickly cover what this technology is and how it works.

How TSM work?

TSM utilizes an electronic stability control system with integrated sensors and microprocessors that act to correct skidding and prevent side-to-side fishtailing. Here is a quick rundown:

• Gyro sensor in the TSM module detects steering/chassis motion and angle changes.
• Data is sent to the microprocessor 25 times per second.
• TSM determines if correction is needed to regain stability.
• TSM sends signals to a steering servo with integrated motor to countersteer as needed.
• This electronic system provides subtle steering corrections to keep your Traxxas vehicle stable.

The result is a more optimized, controlled driving experience, even at high speeds.

Benefits of TSM

When operating correctly, TSM offers the following advantages:

• Smoother, straighter steering, especially at high speeds
• Reduced fishtailing through corners
• Helps correct oversteer or understeer tendencies
• Makes models easier to control for new drivers
• Builds driver confidence allowing them to push the limits

In short, TSM takes much of the work out of ensuring a stable platform and lets you focus on driving. But to leverage these benefits, TSM must be functioning properly. Let’s look at some of the typical causes when that’s not the case.

Common Reasons TSM May Not Work Properly

If you notice your Traxxas RC car with TSM technology seems loose or squirrelly, there are several possible culprits to inspect. Here are some of the most common reasons TSM may stop working correctly:

Loose Steering Components

Like most things on an RC model, the steering must be properly tuned and free of slop for peak performance. Any play or binding in the steering can send false signals back to the TSM system and impede its ability to make effective corrections. Pay close attention to the 

Following:

• Steering hub and wheel nuts tight
• No vertical play in steering posts/rod ends
• Minimal play in the steering rack
• Driveshafts not binding
• No grittiness in the steering assembly

Bad Receiver Connection

For the TSM module to do its job, it must receive continuous, uninterrupted signal from the receiver. A faulty connection here can lead to TSM dropouts or delayed reactions as data flow is disrupted.

Inspect the leads and ensure the receiver, TSM module, and servo connections are all securely plugged in. Also, check for any damaged wires or frayed solder joints.

Faulty TSM Module

Like any electronic component, the TSM module itself can occasionally malfunction. Issues like worn out sensors, corrupt microprocessor programming, or physical damage from crashes can all impair TSM functionality.

If you’ve ruled out other issues, try resetting or reprogramming the TSM module through your transmitter. Or test with a known good module.

Incorrect Transmitter Settings

Part of dialing in optimally performing TSM is fine-tuning the sensitivity adjustment in your transmitter. If this is set too low, TSM may not be active enough. And too high sensitivity can make it overly reactive.

Double-check your transmitter settings and follow the recommendations for your specific model. Reset to factory settings if needed.

Bad Servo

The steering servo is the final piece of the TSM puzzle. It receives signals from the module and executes the subtle steering corrections needed to keep your model stable.

A servo that is damaged, underpowered, or not responsive enough can’t deliver proper TSM steering inputs. Test to make sure your installed servo is working properly.

Low Battery Voltage

Like most electronics, the TSM system needs adequate battery voltage to operate fully and quickly. As your battery starts running low, the TSM module and servo response time may begin to suffer.

Make sure your battery is fully charged when troubleshooting TSM. Old batteries with reduced capacity could also be the culprit.

Now that we’ve covered some of the typical causes of TSM problems, let’s move on to concrete troubleshooting tips.

Troubleshooting Tips to Get TSM Working Again

If your Traxxas TSM system is not functioning properly, here are some helpful troubleshooting steps:

Inspect the Steering Components

Give your steering system a thorough inspection looking for any binding, looseness, gritty feel, or excessive play:

• Ensure wheel nuts and steering hub are tight
• Check vertical and horizontal play in steering posts
• Inspect steering rack and pinion/spur gear mesh
• Make sure drive shafts are free of grit and binding
• Confirm proper toe angle

Make any adjustments or repairs needed to restore smooth, slop-free steering action.

Check Receiver and Module Connections

Closely examine the receiver, TSM module, and servo lead connections:

• Remove and reseat all connectors, ensuring they are properly aligned and latched
• Check for damaged wires, frayed insulation, or broken internal pins
• Verify receiver and TSM module are securely mounted with no vibration
• Examine solder joints for cracks or cold joints
• Swap in new wires or solderless connectors if any issue is found

Solid connections are critical for proper communication.

Reset the TSM Module

Try resetting and recalibrating the TSM module:

• With transmitter off, disconnect TSM module from the receiver
• Hold SET button on module for 10+ seconds to reset to defaults
• Reconnect module and power on transmitter/receiver
• Recalibrate TSM following your model’s instructions

This can clear up any corruption or programming issues.

Double Check Transmitter Settings

Verify your transmitter TSM settings are dialed in correctly:

• Turn transmitter dial to match TSM mode of your vehicle (Race, Sport, Crawl)
• Check that TSM sensitivity is at recommended baseline setting for model
• Reset transmitter to factory defaults if unsure of settings
• Perform any transmitter calibration routines

Proper programming is essential for TSM operation.

Test or Replace the Servo

An inadequate or malfunctioning servo can undermine TSM performance:

• Verify installed servo is recommended for your model
• Check for binding, stripped gears, or loose parts
• Test servo operation/centering via transmitter
• Replace servo with a known good unit if any issues

Having a servo with precision and rapid response is key.

Check Battery Voltage

While troubleshooting, ensure your battery is fully charged:

• Check and charge battery before testing
• Test voltage under load for true reading
• Replace battery if capacity seems reduced
• Switch to a higher C rating battery for maximum voltage under load

Low voltage can definitely contribute to TSM problems.

Calibrate TSM

After any repairs or replacements, recalibrate TSM per manufacturer instructions:

• With model off and motionless, turn transmitter on
• Pay close attention to steering while throttle is increased
• Make small adjustments to TSM dial until you achieve a balanced feel

Proper calibration is important for TSM to work optimally.

By methodically working through these troubleshooting steps, you should be able to determine what is causing your Traxxas TSM issues and take action to restore smooth, responsive steering control. Let’s now quickly review some tips to avoid TSM problems altogether.
