Just got first Harley. 2001 fatboy. No security system. FI. Bike runs great.
When I first turn on switch, turn signals blink 5 times and when I start bike engine light comes on for several secs. and goes out. I have been reading posts all day as to what to do.
1. Used the jumper on data link to get DTC. It gives me code: 1 , 6 over and over. From what I can tell on chart 16 is battery voltage low or battery voltage high. When I got bike it had a bad battery. I put new one in. Could this be where this code came from? And if so how do I clear it.
2. I also tried to get code by turning on switch and pushing left and right turn signal switches as shown in earlier post. It gives me code: 3 , 1 over and over. I have found no chart as to what this means. Can anyone help? I then tried to clear this code as per earlier post, but it will not clear and turn signals keep blinking 5 times when I turn on Switch. Can anyone Help?

TSM/TSSM Rapid Flashing Signals
M-1115 1 of 1
SERVICE BULLETIN
Purpose
Harley-Davidson wants to assure that dealers are using the
proper setup procedure for turn signal modules (TSMs) and
turn signal security modules (TSSMs). This procedure is
required because motorcycles equipped with a self-calibrating
TSM/TSSM are designed to work with a variety of turn
signal light bulbs with different current loads (domestic and
HDI bulbs have different current requirements). The procedure
outlined below allows the TSM/TSSM to measure the
turn signal current draw when all turn signal light bulbs are
operating properly. This procedure must be re-initiated after
each time the vehicle’s battery power is removed or interrupted
so that the TSM/TSSM continues to operate properly.
When a turn signal light bulb burns out, the TSM/TSSM
detects the difference in current draw and flashes the turn
signal/indicator lamp at a rate double that of normal operation,
informing the operator that a turn signal light bulb is not
operational.
Motorcycles Involved
●
All 2001-2002 models except Sportster.
●
2000 models that have been equipped with accessory
Harley-Davidson security systems listed in Table 1.
Required Dealer Action
If battery power to the motorcycle is removed or interrupted
for any reason, the following procedure must be performed to
ensure the turn signal module continues to operate properly.
This must be done before delivery of a new or repaired vehicle.
1. Reconnect battery per service manual procedures.
2. Turn the ignition switch to the IGN position.
NOTE
During the next two steps, observe the turn signals to ensure
that all bulbs are operating. If you detect a burned out turn
signal bulb, turn off the ignition switch, replace the bulb and
disconnect the battery. Then repeat this procedure beginning
with Step 1.
3. Actuate the left turn signal. Allow the turn signal bulbs to
flash at least five times.
4. Actuate the right turn signal. Allow the turn signal bulbs
to flash at least five times.
5. Turn off the ignition switch.
