Turn signal problem.

Turn Signal Lamps
The STOP/TURN/HAZARD fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the body control module (BCM) for the turn signal lamps. When the turn switch is placed in the LEFT TURN or RIGHT TURN position, ground is applied from G202 through the turn switch, to the turn signal switch signal circuit and to the BCM. The BCM then applies battery positive voltage to front and rear turn signal lamps supply voltage circuits. The left front turn signal lamp is grounded at G100, right front at G101, left rear at G301 and the right rear is at G302.

Turn Signal Reminder
The driver information center (DIC) activates the turn signal warning as requested by either turn signal switch. The turn signal warning sounds when the following occurs:
• The ignition is in RUN.
• The turn signal switch is in either turn position, sensing, within 1 second, an open to battery positive voltage transition in the turn signal control circuit, left or right turn.
• The vehicle has traveled a distance of 1.2 km (0.75 mi) by counting pulses in the rolling odometer class 2 message.
The DIC turns OFF the turn signal reminder when either the ignition switch is turned to the OFF position, or the turn signal switch returns to the OFF position, sensing within 1 second, no transitions from open to battery positive voltage in either of the turn signal control circuits, left turn or right turn.

My first step would be to hook up a factory scan tool an check for DTC'S - diagnostic trouble codes

DTC B3948 Left Front Turn Signal Circuit
Circuit Description
Ground is applied to the turn signal switch. When the turn signal switch is placed in the turn left position, ground is applied to the body control module (BCM) through the left turn signal switch circuit. The BCM then applies a pulsating voltage to the LF and LR turn signal lamps through the LF and LR turn signal voltage supply circuits.

What's the left rear lamp doing ? Flashing fast ?

DTC B3950 Left Rear Turn Signal Circuit

Look for a bad ground on the circuits. If you dont have a good ground the circuit will back feed looking for a ground. Try it.

ck your turn signal switch wiring connector because it is more than likely has been hot and melted some connections.

If you've got that Engine light coming On for 4 seconds, Off 4 seconds then On 8 seconds then out, its historic. (there WAS a problem that has now cleared)
If its On 4, Off 4 then remains On its a 'current' code.

I never heard of a #2 code.....they are read as a two digit code.

Here's one method some use to clear all codes:

Disarm alarm if so equipped.
Run/Off switch to OFF
Ignition Key: ON,OFF,ON,OFF,ON (and leave ON)
Press LEFT turn signal switch TWICE. Wait for 1 or 2 flashes..
Press RIGHT turn signal switch ONCE => turn signal will flash 1 time
Press RIGHT turn signal switch ONCE => turn signal flashes 2 times
Press RIGHT turn Signal switch ONCE => turn signals flash 3 times
Press LEFT turn signal switch ONCE. TROUBLE CODES WILL NOW BE DISPLAYED
TO CLEAR ANY CODES,,,=> PRESS & HOLD LEFT signal switch for 5 seconds. => turn
signal will now flash twice to confirm memory is clear.
Turn ignition OFF.

Makes no diff left or right turn, there's one flasher under the dash next to steering columb. Possibly in the fuse panel, but I don't think so. Turn the switch on and flip the signal, listen for the relay/flasher to be clicking. That's the easy way to find it. Even if all you can do is feel the unit flashing. Pull it down and change it. Just plugs into the accessory block.

Key fob MUST be present near bike!
1. Select 5 digit code ( each digit being a 1 thru 9) and record it on the wallet card in the owners manual.
2. With an assigned FOB present, turn IGN key ON - OFF - ON - OFF - ON
3. Press Left turn signal switch 3 times.
4. Press Right turn signal switch one time and release.
*Turn signals will flash 3 times. Current PIN will appear in the odometer. The first digit will be flashing.
TO ENTER NEW PIN:
5. Enter first digit (a) of the new PIN by pressing left turn signal (a) times.
6. Press right turn signal 1 time and release.
*The new digit (a) will replace the current in the odometer window.
7. Enter second digit (b) of the new PIN by pressing left turn signal switch (b) times.
8. Press right turn signal 1 time and release.
*The new digit will replace the current in odometer window.
9. Enter the third digit (c) of the new PIN by pressing left turn signal (c) times.
10. Press the right turn switch 1 time and release.
*The new digit (c) will replace the current in the odometer window.
11. Enter forth digit (d) of the new PIN by pressing left turn signal switch (d) times.
12. Press the right turn switch 1 time and release.
13. Enter the fifth digit (e) of the new PIN by pressing left turn signal (e) times.
*The new digit (e) will replace the current in the odometer window.
14. Press the right turn switch 1 time and release.
15. Before the module rearms, turn ignition key to OFF.
* The odometer will return to mileage display.
**Turning the ignition to OFF stores the new pin in the module.



Using the Security Alarm PIN Override to Start Your Harley Davidson

1. Turn the IGN key to IGNITION and immediately hold both turn signal switches until 5 dashes appear in the odometer window.
2. Enter the first digit of your PIN (a) by pressing the left turn signal switch (a) times.
3. Press the right turn signal switch 1 time to move to the next digit.
4. Enter the second digit of your PIN (b) by pressing the left turn signal switch (b) times.
5. Press the right turn signal switch 1 time to move to the next digit.
6. Enter the third digit of your PIN (c) by pressing the left turn signal switch (c) times.
7. Press the right turn signal switch 1 time to move to the next digit.
8. Enter the forth digit of your PIN (d) by pressing the left turn signal switch (d) times.
9. Press the right turn signal switch 1 time to move to the next digit.
10. Enter the fifth digit of your PIN (e) by pressing the left turn signal switch (e) times.
11. Press the right turn signal switch 1 time to move to the next digit.
12. Press the right turn signal switch one time and the security system alarm is turned off.

that sounds like your switch is bad on that side.

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.

SOUNDS LIKE YOU HAVE A FAULTY MULTIFUNCTION SWITCH

If the fuses are good and the front and rear bulbs are good, change the flasher for the turn signals, even tho the right is working. If that doesn't fix the problem, it might be in the turn sgnal switch on the steering column.
If both bulbs are good for the backup lights and fuses are good, then the backup light switch, which is screwed into the side of the transmission has to bad.
