Is the TSM-2 compatible with LED turn signal upgrades?

Yes, the TSM-2 is fully compatible with both LED and incandescent bulbs. It supports LED loads from 0.24A to 6A per side and works with BCM-compliant LED upgrades without requiring an additional load equalizer.

Which OEM modules does the TSM-2 replace?

The TSM-2 replaces OEM TSM (Turn Signal Module) 68921-01 and TSSM (Turn Signal Security Module) models 68923-00 (US models) and 68925-00 (HDI/EU models). Note: It functions as a TSM only and does not support TSSM factory alarm features.

Do I need a load equalizer when installing the TSM-2?

No load equalizer is required. The TSM-2 is compatible with BCM-compliant LED upgrades and handles the full load range of 0.24A to 6A per side without additional components.

How does the auto-canceling turn signal feature work?

The TSM-2 features intelligent auto-canceling based on three factors: speed detection, time elapsed, and direction change. The module automatically deactivates your turn signals when riding conditions suggest they should be off, reducing manual intervention.

What is the tilt protection feature and how does it work?

The built-in tilt protection automatically shuts off the module if your motorcycle leans beyond 45 degrees for more than one second. This prevents signal malfunction during cornering and adds an extra safety layer.

Is professional installation required or can I install it myself?

The TSM-2 is a plug-and-play replacement with included installation instructions. For most 01-06 Softail and 04-06 Dyna models, manual module pairing is possible. However, some models require a TechnoResearch diagnostic tool for TSSM module replacement procedures.

Does the TSM-2 support OEM manual password learning?

Yes, the TSM-2 supports OEM TSM manual password learning compatibility. It also supports TechnoResearch diagnostic tool programming for advanced module replacement procedures on compatible models.

What protection does the TSM-2 offer against electrical damage?

The TSM-2 includes built-in short circuit and overcurrent protection to safeguard your motorcycle's electrical system. This prevents damage from wiring mistakes or component failures during installation and normal operation.
