2002 Harley-Davidson FLST/FXST Softail OEM Service & Repair Manual

2002 Softail: TSM & TSSM 3-1 HOME TSM/TSSM OVERVIEW 3.1 GENERAL See Figure 3-1. The turn signal module (TSM) has two major functions: ● Control turn signals. ● Serve as bank angle sensor. The optional, factory-installed, security system (turn signal security module or TSSM) provides the same functionality as the TSM, but also includes: ● Security and immobilization functions. See 3.2 TSM/TSSM FEATURES for complete details. TROUBLESHOOTING Problems fall into at least one of four categories: ● Turn signal malfunction. ● Bank angle (engine disable). ● Security lamp problem (TSSM only). ● Security system malfunction (TSSM only). To resolve TSM/TSSM problems, five basic steps are involved. In order of occurrence, they are: 1. Check for trouble codes by observing the turn signals. See 3.8 CHECKING FOR TROUBLE CODES: TSM/ TSSM. 2. Retrieve trouble codes using SCANALYZER (Part No. HD-41325) or TSM/TSSM diagnostics. See 3.11 SCAN- ALYZER: EFI MODELS ONLY or 3.8 CHECKING FOR TROUBLE CODES: TSM/TSSM. 3. Diagnose system problems. This involves using special tools and the diagnostic flow charts in this section. 4. Correct problems through the replacement and/or repair of the affected components. 5. After repairs are performed, the work must be validated. This involves clearing the trouble codes and confirming proper vehicle operation as indicated by the behavior of the turn signals. Figure 3-1. TSM/TSSM Figure 3-2. Key Fob 7844 s0457xtm

2002 Softail: TSM & TSSM 3-3 HOME TSM/TSSM FEATURES 3.2 GENERAL The TSM/TSSM provides the following capabilities. Note that some hardware options and software settings are dependent upon vehicle market specifications. TURN SIGNAL FUNCTIONS TSM/TSSM Features See 3.4 TSM/TSSM TURN SIGNAL FUNCTIONS for complete details. ● Manual turn signal control: Manual activation/deactiva- tion of left and right turn signal flashing sequences. ● Automatic turn signal cancellation: Automatic cancellation of left and right turn signal flashing sequences based on either vehicle speed, vehicle acceleration or turn completion. ● Emergency flashers: Four-way left and right turn signal flashing capability. ● Turn signal lamp diagnostics: Self-diagnostics for short circuit and open lamp conditions on both left and right turn signal systems. BANK ANGLE FUNCTIONS TSM/TSSM Features See 3.5 TSM/TSSM BANK ANGLE FUNCTION for complete details. ● Emergency engine shutdown: Monitors vehicle lean and will provide engine shutdown when lean exceeds 45° from vertical for more than one second. ● Emergency outputs disable: Monitors vehicle lean and will disable turn signal lamps and starter motor when lean exceeds 45° from vertical for more than one second. SECURITY ALARM AND IMMOBILIZATION FUNCTIONS TSSM Only Feature The following information applies only to vehicles with the security option (TSSM). See 3.6 SECURITY SYSTEM (TSSM) FUNCTIONS for more information. ● Remote arming/disarming: See Figure 3-4. Owners may enable and disable security alarm and immobilization functions with a remote, personally carried transmitter. This transmitter is referred to as a key fob within this document. ● Security status lamp: See Figure 3-5. A lamp within the speedometer face tells the rider if the system is armed or disarmed. ● Personal code disarming: If a key fob is not available, the TSSM allows the rider to disable the security alarm and immobilization functions if the rider knows the previ- ously entered personal code. ● Security command confirmation: When the system is armed or disarmed, the system provides visual feedback to the rider by flashing the turn signals and sounding the optional siren.

3-4 2002 Softail: TSM & TSSM HOME ● Auto-arming: Automatically enables the security alarm and immobilization functions when the ignition key is switched OFF. NOTE Default auto-arming behavior depends upon vehicle market. All HDI vehicles have auto-arming by default. Motorcycles sold in other markets have auto-arming disabled, but it may be activated. See 3.3 TSM/TSSM VEHICLE DELIVERY. ● Transport mode: It is possible to arm the security system without enabling the motion detector for one ignition cycle. This allows the vehicle to be moved in an immobi- lized state. ● Starter/ignition disable: Should the security alarm and immobilization functions be triggered by a vehicle security condition, the starter and ignition system will be disabled. ● Security system alarm: See Figure 3-6. The system will alternately ﬂash the left and right turn signals and sound an optional siren if a vehicle security condition is detected while the system is armed. Figure 3-6. Siren o0236xox

2002 Softail: TSM & TSSM 3-5 HOME TSM/TSSM VEHICLE DELIVERY 3.3 GENERAL 1WARNING 1WARNING ONLY FLT Harley-Davidson Motorcycles are suitable for sidecar use. Consult your Harley-Davidson Dealer. Use of vehicles other than FLT models for this purpose could result in death or serious injury. Setting up a vehicle TSM/TSSM depends on two factors: ● Does the vehicle have a sidecar attached? ● Does the vehicle have a turn signal module (TSM) or the optional security system (TSSM) installed? All motorcycles ship with the TSM/TSSM set for use without a sidecar installed. If a motorcycle is equipped with a TSM, no further configuration is required. However, if a motorcycle has a sidecar or an optional security system (TSSM) installed, perform the following steps as necessary. CAUTION If the vehicle is being operated with a sidecar, the setting MUST be switched from solo vehicle operation to sidecar operation or the TSM/TSSM will not function properly. 1. Configure the TSM/TSSM for sidecar or solo configuration. If no sidecar is installed, skip this step. 2. Configure TSSM motorcycles by assigning both key fobs to the vehicle. 3. Configure TSSM motorcycles by entering a personal code picked by the owner. The personal code allows the owner to operate the system if the key fob is lost or inop- erable. Record this code in the owner’s manual and instruct the customer to carry a copy. IMPORTANT NOTE Do not forget to enter a personal code for TSSM vehicles. If a code is not assigned and the key fob is lost or damaged while the vehicle is armed, the TSSM must be replaced. Changes to TSM/TSSM settings are made by a series of programming operations involving the ignition key, left/right turn signal switches and key fob (security systems). At certain steps in the programming sequence, the motorcycle may provide confirmation of settings by flashing the turn signals, turn signal indicators and/or security lamp. All programming operations are listed in table format. Follow the numbered steps to configure the system. If a confirmation response is listed, wait for the confirmation before continuing to the next step. Important information pertaining to certain actions will be found in the NOTES column. USING SCANALYZER ON EFI MODELS The SCANALYZER CARTRIDGE (Part No. HD-41325-95C) has TSM/TSSM configuration capability on fuel injected Sof- tails. SIDECAR CONFIGURATION 1WARNING 1WARNING ONLY FLT Harley-Davidson Motorcycles are suitable for sidecar use. Consult your Harley-Davidson Dealer. Use of vehicles other than FLT models for this purpose could result in death or serious injury. On motorcycles with a sidecar, the TSM/TSSM must be switched from the factory solo vehicle setting to the sidecar setting. See Table 3-1. If a sidecar is removed from the motorcycle, the TSM/TSSM must be reconfigured. See Table 3-2. POWER DISRUPTION AND CONFIGURING The TSM/TSSM will not enter configuration mode on the first attempt after battery voltage has been removed from Pin 1. This will occur after any of the following situations: ● Battery disconnect or power drain. ● Security fuse removal. ● Connecting Breakout Box to TSM/TSSM connector. Therefore, after all battery reconnects, the configuration sequence must be modified as follows. 1. Set run switch to OFF , cycle ignition key ON-OFF-ON- OFF-ON and press left turn signal switch twice. 2. Repeat step listed above. 3. Continue with configuration sequence listed.
