Reading codes

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.

*sigh* In my usual incompetent fashion, I can't get past step 2. When I push the odo reset button (with ignition off and run switch on), the mileage comes up but nothing else happens - no blinking. What am I doing wrong, please?
That did it, thanks. Current P 1354 Rear ignition coil open/low.
