If an EFI or related chassis component fails or an out-of-tolerance signal is detected by the ECU, a malfunction code will be generated in the ECU and displayed on the LCD. For the first thirty seconds, the LCD will go blank and the malfunction code will be displayed alternately with a wrench icon or malfunction indicator light (MIL). After thirty seconds, the digital display will return to normal; however, the MIL and malfunction code will continue to flash. On models equipped with the analog gauge, the needle will swing full-scale for thirty seconds; then return to normal with the MIL and code continuing to flash.

Code List
NOTE: Each of the following numerical codes will have a one-letter prefix of C or P. A “C” prefix denotes a chassis malfunction and a “P” prefix denotes a power train malfunction.
NOTE: Normal malfunction codes are cleared from the LCD when the component is replaced or the malfunction is corrected; however, intermittent codes must be cleared as noted in the code chart.

If an ECU, ISC or TPS sensor is replace, the following process must be completed.
  1. Hold the throttle wide open
  2. Key ON (DON'T START) and wait 10 seconds
  3. Release the throttle and wait 10 seconds
  4. Key off and wait for the gauge to power down
  5. Key on, ISA and TPS reset
  6. .

There is a more extensive list here:http://www.arcticchat.com/forum/procross-proclimb-chassis-general-discussion/362472-list-ecu-trouble-codes.html
It covers all product lines, and is big

The code list is for the newer machines with CAN comunication to the gauge. easiest way to tell is that they have a metal ecu housing. There is no set cutoff, as they adopted the new efi at different times for different engines

If you have a newer machine with a metal ECU housing do not jumper it. You can pull the codes up on the dash.
