Reading codes

157832 Views 204 Replies 79 Participants Last post by  TaxmanHog
The IM (instrument module) is capable of displaying DTC's (diagnostic trouble codes).

  1. Ignition off
  2. push the odometer reset button in & hold. Make sure the run switch is on.
  3. turn ignition to run and release the button (you will see P, S &C displayed)
  4. each letter represents an area of diagnostics... the one that is flashing is the one you are going to check. To move from one letter to the next, you push the button one time. (from P to S to C and back to P, etc.)
  5. to get DTC within an area, you push and hold the button in for 5 seconds and if there are any, it will be displayed... you can release the button. As you push the button again, other codes will appear if they are there. If there are not any the word 'none' appears.
  6. Record the codes.
  7. To determine if a code is current or historic, you clear the codes while being displayed by pushing in and holding the button until 'clear' comes up. Turn off the ignition... then crank or restart the bike... turn off, and then repeat the coding process. If a code is there now, it's current... if not, it was historic.

i have tried pulling codes from the IM but i dont get anything at all just the milage when i press and hold as per the instructions on the first post. just wondering if the power commander has to be unplugged? will the ecu lose the codes if i unplug from harness?
nevermind i was doing one of the steps backwards must be the beers i had prior. i got a code p1356 seems to be the rear coil. i guess i might as well do both and put fresh plugs
Hi All Im kid of new to this, and don't even know if this is an active thread. Anyway my problem is code b1005 (current fuelsender open/high on my 02 vrsca. i cleared them and retested and they were active. check manual couldnt find fuel sender. So i unpluged maxi fuse and retested and it was clear. is this something i have to worry about? or what should i do next? Thanks

Fuel sender information including the discussion of this DTC is in the Electrical Diagnostic Manual (99499-02 for your bike) in Section 2.9 (page 2-22).

The B1005 code is usually set when you forget to plug in the fuel module connector under the seat. This DTC can also set if the IM (Instrument Module) isn't plugged in but that would set the U1096 (loss of IM serial data) DTC at the same time. Another possible fault would be a break in the yellow wire that runs from the IM pin #11 to the fuel module.
Thanks for the info. the code is now missing. But! it still wont hardly idle. looks like i will be purchasing elect. diag. manual. Thanks again
anyone know what these "rolling codes" mean? I know it's part numbers but I don't remember ever seeing them there before. anyone else get these? i posted in another thread but it was no help so i'm hoping i get an answer here. thanks.

i got a few "rolling code" after i cleared the codes under P S C. these codes would roll across the screen after i cleared the codes in P S C and here they are.

PN 1599 002-
PN 67453-07
PN 68925-07

Those aren't DTCs. They just indicate what modules are responding on the serial bus (datalink).

The first number doesn't make sense to me but 67453-xx is an IM (instrument module) and 68925-xx is a TSM/TSSM/HFSM = security system.

thanks stever. what a helpful post. i'm glad i can get positive answers to my questions...:stilpoke::stilpoke::stilpoke::stilpoke:
amazing post ..
did follow procedures and cleared "6221.. somthing" under S ..
i had an issue with shuttin engine while exceeding 4000 RPM !!
i'll ride it tomorrow and check again diagnosing the problem
just got 61005 wtf is that?

You're miss-reading B1005. This is FUEL SENDER OPEN/HIGH. I'm guessing you didn't plug the fuel sender connector in under your seat.

I never touched it. Are you saying it can come loose? This was my first ride of 2011 & at the end of the day the CEL came on & I pulled that code.

It's never come loose on my bike but for a 2003 VRSC bike, DTC B1005 means the fuel level sender wire (yellow with a white stripe = Y/W) from pin # 11 of the IM (instrument module) isn't connected to the variable resistor connected to the float in the fuel tank.

The fuel tank connector has three wires:
#1 is yellow with a green stripe (Y/GN) to the fuel pump
#2 is Y/W to the resistor
#3 is black (BK) and goes to ground​

Usually the problem is a bad connection at either the IM or the fuel tank module but it could be a pinched Y/W wire. If the tank module connector was disconnected or the BK wire was bad the fuel pump wouldn't work and the engine wouldn't run. There's a more rare possibility that the IM is bad.

The bike runs fine, so you're saying that I'll have to lift up the seat & check the wires that lead into that black square thing & make sure that they are all in place?

I'm not sure what electrical diagnostic tools you have or if you know how to check continuity but someone needs to check and make sure that the Y/W wire is connected to the fuel tank resistor. The resistance from pin #11 of the IM connector to ground should be no greater than about 300 ohms. If the resistance is higher than this, there's something wrong with the Y/W wire, the tank connector, or a connector inside the tank.

Ok Steve I'll get together with a buddy of mine who's pretty good electrically & we'll see what we come up with. Thanks for all your input. I wanna stay out of the stealership as much as I can. They replaced my fuel flange 2 years ago @ 3800 miles. I now have 9100 miles on it.

Steve, I started & ran the bike today for like 10 minutes & it was fine. No CEL

So I went ahead & performed the diagnostic sequence.

"PSC" - The code came up under "C". It followed with Pn 67392-01A

I just Googled the part # & it says I need a new instrument cluster!?!??!!? wtf

No you don't need to replace the IM. When a part number is displayed it's just indicating what particular module or module flash that's communicating on the serial bus.

Its posts like this that make this forum such a great source of info! Stever, you are the man! :notworth:
