Neon Trouble Code Info
Turn the ignition ON-OFF-ON-OFF and ON (not start) within 5 seconds.
Count the number of times the "check engine" lamp on the instrument panel flashes on and off. The number of flashes represents the code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual codes. FLASH, FLASH, FLASH, pause, FLASH, FLASH = code 32.
A code of "55" represents end of error codes. If you only get this code, then no error codes are stored in the computer.

* Check Engine Lamp (MIL) will not illuminate if this Diagnostic Trouble Code was recorded. Cycle Ignition key as described under How to Display and Read Diagnostic Trouble Codes and observe code flashed by Check Engine lamp.
** Check Engine Lamp (MIL) will illuminate during engine operation if this Diagnostic Trouble Code was recorded.
*** Generator Lamp illuminated
