Harley Davidson Security System Removal – A Step-by-Step Guide

Are you fed up with having to constantly deal with dead FOB batteries from your Harley Davidson’s security system? You’re not alone. Thankfully, there is a way for you to remove the Turn Signal Security Module (TSSM) on your ’07 and later touring bike without needing professional assistance. In this article we will provide an easy-to-follow guide that will help make the Harley Davidson security system removal process hassle free.

Purchase the necessary part

Prior to taking out the TSSM, you ought to obtain a substitute part. Fortunately, Harley Davidson’s Turn Signal Security Module (TSSM) can be exchanged with a non-security equipped Turn Signal Module (TSM). The related HD part number is 68920-07 and should cost around $114 from official dealers; however, it might also be found on eBay for much cheaper than that.

Locate and remove the TSSM

Positioned vertically on the right (starboard) side of your bike, beneath the seat lies a cone-shaped device contained in a black plastic case. Easily unscrew the silver metal clip to remove it and lift out the TSSM with ease.

You’ll see two connectors protruding from the device. Disconnect them both, being sure to remember that one plug is larger than the other. This bigger connector connects to the input, ECM and turn signal – we will reuse this shortly. The smaller part represents output for pager and siren – save it by taping it up safely so you can use it later on down the line.

Replace the TSSM with a TSM

Carefully insert the larger connector into your newly acquired TSM, and delicately slide it back in its original position; make sure to store the small connector securely so that it can’t be rattled or damaged. To deactivate the security system, one must replace their existing TSSM with a new TSM; however, this alone is not enough for your bike to function properly.

Perform the necessary steps to reprogram the bike’s ECM

In order to get your bike running with the new TSM, you must reprogram its Electronic Control Module (ECM) by taking the following measures:

  1. Prior to beginning the procedure, ensure that the ignition has been switched off for a minimum of 15 seconds.
  2. Move the Run/Off switch to RUN.
  3. Don’t start the engine yet; simply turn the ignition key on and make sure that both the Check Engine Light and Security Lights come on, then wait for them to go out.
  4. To initiate the process, press Start. The engine should start and then abruptly shut off. Afterwards, the Check Engine Light will illuminate and remain illuminated until further notice.
  5. Allow ten seconds to pass. The Security Light will now be illuminated signaling that the ECM is properly engaged in dialogue with the TSM for a span of ten minutes. To avoid any disruptions, glance at your timepiece and use this period of waiting wisely by tending to tasks such as polishing fenders or similar activities – but make sure not to turn off your bike’s engine, discharge its battery power, switch anything on/off or unplug any electrical appliance during these critical moments.
  6. After ten minutes, the security light will automatically switch off. Within 15 seconds of it turning off, quickly twist your ignition key Off and back On again – this should be done in two seconds or less for best results. As soon as you do that, watch out for the Security Light coming on once more – then wait another ten minutes before continuing with the process.
  7. Once the Security light has gone out, repeat Step Six for reinstatement.
  8. When the Security Light goes out, begin by doing the Off-On sequence. Once it lights up again, turn off your ignition and wait at least 15 seconds to disconnect your battery charger from both the wall outlet and bike. Finally switch on your ignition once more with an additional confirmation of neutral before starting up your engine.
  9. Rejoice in the newfound liberty of your bike, now without a security system.

Congratulations. You have now completed the reprogramming process and Harley Davidson security system removal from your bike.
