That method does not work on an 02

 

Mr Wizz.

I have a 2002 service manual but do electrical diagnostic one. However, I have a 1999 - 2005 manual that has this. It actually says you can't clear them without a Harley reader. Usually, if you leave everthing hooked up and just remove proper fuse, you can but but system needs to have two fuses for ecm to do that.

Diagnostic trouble codes are displayed as a series of flashes at the check-engine light on the speedometer face. To retrieve the stored codes, a jumper wire made of 18-gauge wire and two Deutsch sockets (H-D part No. 72191-94), shown in Figure 38, are required. To retrieve the diagnostic code(s), perform the following: 1. Remove the seat as described in Chapter Fourteen. 2. Remove the right side saddlebag as described in Chapter Fourteen. 3. Remove the frame right side cover. 4. Lift the data link connector (A, Figure 39) up and off the mounting bracket. 5. Remove the protective cover (B, Figure 39) from the data link connector. 6. Install the jumper wire onto pins No. 1 (green/red) and No. 2 (black) on the data link connector. 7. Turn the ignition/light key switch to the IGNITION position. After approximately eight seconds, the different systems enter the diagnostic codes: a. The check engine light begins with a ready signal, which is a series of six rapid flashes, approximately three per second. The ready signal indicates the check engine light is ready to flash a diagnostic code. b. The ready signal is followed by a two-second pause. c. Then the system flashes the first digit of the stored diagnostic code. The check-engine light will illuminate for one second then turn off for one second.
Codes...
11 Throttle position sensor (EFI) 12 MAP sensor (carbureted) 12 Barometric pressure sensor (EFI) 14 Engine temperature sensor (EFI) 15 Intake air temperature sensor (EFI) 16 Battery positive voltage 23 Front cylinder fuel injector (EFI) 24 Front cylinder ignition coil 25 Rear cylinder ignition coil 32 Rear cylinder fuel injector (EFI) 33 Fuel pump relay (EFI) 35 Tachometer (except FLHR, FLHRCI) 41 Crankshaft position sensor 42 Camshaft position sensor 44 Bank angle sensor 52 RAM error or failure 53 ROM error or failure 54 EPROM error or failure 55 Ignition module failure 56 Camshaft position sensor and crankshaft position sensor timing or signal error

Be real careful here. I do not have enough detail here to even know if above applies to your 2002. Seems to be nothing on YOU Tube on a 2002. Like the guy said about his 2000.

You really need to make sure all details apply before one starts jumping pins on anything. Sometimes, a piece of black tape over a light is safer...

 

Damn, wonder what it would cost to get someone to read the codes, may call my local bike shop, not HD, and ask them

 

It’s not complicated. Carefully jumper the pins or backprobe them (with a jumper) and read the blinks.

 

PS. I was working on below when Ed posted above me me post 14.


Ed in this thread confirms the pins

Also, if you google search 2002 Harley Davidson code reader , appears the adapter is about $20 and the​​​​​​ readers are 100.

Be sure to read detail on if they clear. You can easly read them by following post 12.

The flashes and counts will be obvious after you watch it a few times. Watch the video in post 10. Will be similar. Just different in the way you start it

I doubt most Harley shops would even work on it when the get that old but they may.

My guess is an hour to read and clear if all the part changers don't run out the back door.

 

What does the next page say about deleting stored codes?
What EFI system does this bike have? The M&M?

 

For me, an intermittent CEL was caused by a failing voltage regulator.

 

anyone want to buy my vintage HD code reader?

Works on the 02 bikes... it worked on my 03

Now that I have a Snap On Solus with the HD cables I can use that to get into the ECM

 

Will it clear codes?

 

yes
