Left turn signal will not work, cycle ignition swith light will flash

The smart flasher (GMSF) is an automotive flasher designed to accept turn, hazard, and brake inputs. The GMSF will provide corresponding outputs to the exterior lamps and instrument panel turn signal indicator lamps. This lighting system has dedicated lamps for the turn/hazard functions and dedicated lamps for the brake function. The system incorporates the use of flash rates for diagnostics. The flash rate is a calculation of the number of flashes that occur within a 60 second period. This system uses a percentage of on-time to off-time called duty cycle. For the bulb outage condition, the indicator of the vehicle side on which the outage occurs shall assume bulb outage flash rate mode. The opposite side indicator will assume the normal flash rate mode for an input from the non bulb outage side of the vehicle. Hazard warning lamp outage will maintain a normal flash rate as long as 2 or more exterior signaling lamps are functional. During all modes of operation, the IPC will receive the same flash rates and duty cycles that the exterior lamps receive. The IPC will then control the indicators in the cluster. The vehicle operator will be provided with an audible and visual indication of the flasher operation. Below is a table with flash rates and duty cycles:
Operating Condition
Flash Rate
Duty Cycle
Normal
75 to 105 flashes per minute
45% to 55%
Turn Signal Lamp Outage
2 or 3 times faster than normal flash rate
35% to 55%
The IGN E fuse in the engine wiring harness junction block supplies Ignition positive voltage to the turn signal switch assembly. With the ignition switch in the RUN or START position, ignition positive voltage is connected through the turn signal and hazard switch assembly to the GMSF which is powered by the FLASHER fuse also in the engine wiring harness junction block and is grounded at G201. When the turn signal switch is placed in either the left or right position, the circuit is complete from the GMSF to the turn signal lamps and to ground. The GMSF then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators. The front turn signals are grounded at G103 and G107. The rear turn signals are grounded at G401 and G402.
The IPC illuminates the TURN SIGNAL ON indicator in the driver information center when the IPC determines that the turn signal is active for more than 1.2 km (0.75 mile). The IPC also sends a class 2 message to the radio in order to activate the audible warning.
On vehicles equipped with the outside rear view mirror turn signal lamps, the turn signal voltage is also sent to the respective front door module. The door modules then distribute power and ground to the activated lamp.
For trailer wiring, separate turn signal circuits are connected through the GMSF to the trailer wiring harness.

Just left side front and back are not working?

It could need a new turn signal / hazard flasher module.

Could be a number of things. Hooking up a scan tool an checking for codes in the BCM would be the first thing to do. Looking at wiring diagrams an checking electrical circuits would be the next thing to do. Not looking for magical fixes on here. You do say what year it is ,what have you done, checked fuse's ?

2005 Softail ARMING/DISARMING SECURITY SYSTEM (TSSM) 3.7
GENERAL
The security system can be armed automatically by the TSSM when the bike is shut down or manually by the use of the fob and it can be turned off automatically by having the fob within range when the ignition is turned on or by entering the PIN or personal code.

The security system lamp in the speedometer head confirms the status of the system as armed or disarmed.

The range within which the fob will work is dependent on the environmental and geographic conditions so the fob should be held at about waist level and horizontal to the tssm and pointed at the front of the bike with the fob button held down until both of the turn signals flash twice which indicates that the TSSM has responded to the fob and the security system has been activated. To disarm the system the fob should also be held at about waist level and horizontal to the TSSM and pointed at the front of the bike and the fob button rapidly pressed two times within 1.5 seconds after which if the TSSM has responded and turned off the security system the signal lights will flash one time.

The fob is synchronized to the particular TSSM and the fob button should not be pressed very often when it is away from the bike because this might cause it to become de-synchronized to the particular TSSM which would require that the fob button be pressed and held within range of the TSSM for 10 to 15 seconds or until it is re-synchronized and the signal lights flash two times in response.

The personal code (PIN) consists of five numbers or digits each of which can be any number from 1 to 9 that are individually entered into the security system by using the left and right turn signal switches. This number can be used to disarm the security system without the fob. If an error is made while entering the PIN the TSSM will activate the alarm for 30 seconds after the fifth digit is entered and the security lamp will flash every second for ten minutes and there cannot be any further attempts to enter the code during this ten minute period.

The way to enter a personal code is to set the RUN/OFF switch to OFF, turn the IGNITION key to ACC, hold both turn switches in until the security lamp blinks at a fast rate to confirm that the security system is ready for personal code entry, THEN enter the first PIN digit (number) by pressing the left turn switch button a number of times equal to the value of the first digit of the PIN, i.e. for 1 press once for 2 press twice etc., then press the right turn signal switch button 1 time to enter the first number, THEN press the left turn signal switch button the number of times that is equal to the second number of the PIN, followed by pressing the right turn signal switch button 1 time to enter the second number, then press the left signal light switch button the number of times equal to the third number of the PIN followed by pressing the right signal light switch button one time to enter the third number of the PIN, THEN press the button of the left turn signal light switch a number of times equal to the number of the fourth PIN number followed by pressing the right signal light switch button once to enter the fourth PIN number, THEN press the left signal light switch button the number of ties that is equal to the fifth number of the PIN followed by pressing the right turn signal switch button one time to enter this final number of the PIN at which point the security lamp in the speedometer head will stop flashing and the signal lights will flash once to confirm that the security system has been disarmed.

If the security lamp light in the speedometer head does not flash the security system is not armed or the bike does not have a security system or the system if installed is in storage mode.If the security system light in the speedometer head flashes every second for ten minutes there has been a failed PIN entry attempt. If the security system light in the speedometer head flashes once every two seconds the security system is armed. If the security system light in the speedometer head flashes 3 times per second the system is in PIN entry mode. If the security system light stays on solidly with the ignition key OFF auto-arming is commencing and there will be a 30 second period before the system is armed. If the security system light in the speedometer head stays on solidly for more than 4 seconds with the ignition switch ON there is a current DTC(s) set.

With a TSM if the four-way flashers flash 6 times shortly after the ignition switch is turned to ON you should check for DTC's that have been set.

A TSSM diagnosis starts with observation of the security system light in the speedometer head at KEY ON which means that the run switch and the ignition switch are both ON without starting the engine. When the ignition key is turned ON, the security lamp will illuminate for approximately four seconds and then turn off. If the security lamp is not illuminated at Key ON or if it fails to turn OFF after the initial four second period, the speedometer may be defective and need to be replaced. If BUS Er is displayed on the odometer, it may take up to twenty seconds for the security lamp to illuminate. The security lamp will also light for eight seconds after the first four second bulb check period if any historic diagnostic trouble codes (DTCs) are present. After the initial 4 second bulb check period of lamp illumination the security lamp will stay on if current DTCs are set. If a historic DTC is present, the security lamp will continue to light for 50 ignition cycles or until the DTC has been manually cleared away. After the lamp turns off after being illuminated for the first four second period, one of three events may occur: 1.The lamp will remains off which indicates there are no current fault conditions or stored historic DTCs being detected by the TSSM. 2. The lamp stays off for four seconds and then comes back on for an eight-second period which indicates that a historic DTC is stored, but no current DTC exists. 3. If the lamp remains on beyond the eight-second period a current DTC exists.

FOR 2002 Security System 1 long push on the remote turns it on, 2 quick clicks turn it off.

First off, you need to know the PIN.
Setting the PIN is as follows:

Think of a five-digit PIN, and write it down. Think of this set of numbers as a password for starting your bike and disabling the alarm during those times when you don't have your fob.
Turn the ignition key on, then off, then on, then off, then on again. Then press the left turn-signal switch twice. Press the right turn-signal switch once, and the current PIN should appear in your odometer.
Be sure the first digit of the PIN is flashing. Enter the first digit of your new PIN by pressing the left turn signal to cycle through the numbers.
Press the right turn signal once to switch to the second digit, and select the correct number with the left turn signal. Repeat this process until your new PIN is entered correctly.
Press the right turn signal once, then turn the ignition key off to save the PIN you selected.

Now, how to disable:

Let's assume for simplicity that your code is set at 31313 and you wish to use the manual disarm of the security system using the directional switches as if you lost your fob and cannot disarm the system.

Your security system will disarm the bike and it cannot be started without deactivating the system first.

If you are unsure of what the manual code is refer to the top of this page or check with your dealer and set one if it has not been set by them.

Again this is based on your code being 31313 just to make it easier to understand.

1. Turn the ignition to Accessory.

2. Press both turn signals. (security light should flash rapidly)

3. Press left turn signal button 3 times (the 1st "3" of the PIN). Press right turn signal button 1 time (to "set" the code number).

4. Press left turn signal button 1 time (2nd number of PIN). Press right turn signal button 1 time.

5. Press left turn signal button 3 times. Press right turn signal button 1 time.

6. Press left turn signal button 1 time. Press right turn signal button 1 time.

7. Press left turn signal button 3 times. Press right turn signal button 1 time.

Security light stops flashing and security system is disarmed.

If you've changed the number, use your new number instead of 31313.

The signal flasher. Maybe a bulb burned out.

The security, antitheft, or passlock light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle.
This link may help you find ways to bypass this or fix it yourself.

The rear left turn signal bulb must be replaced immediatly before it melts the light socket, if it has'nt yet. Also please verify that the correct light bulb is being installed. because even though many bulbs look the same they are not identical. Installing the wrong bulb can be the begining of many, many problems in the particular circuit

try replacing the signal light flasher that should solve your problem, if it does not then the signal swith needs replacing, most of the time its the flsher,start with that hope this helps,good luck.
