Pgm-Fi Self-Diagnosis Malfunction Indicator Lamp (Mil) Failure Codes - Honda INTERCEPTOR 2002 Service Manual

FUEL SYSTEM {Programm ed Fuel Injection)
PGM-FI SELF-DIAGNOSIS MALFUNCTION INDICATOR LAMP (MIL)
FAILURE CODES
• The PGM-FI MIL denotes the failure codes (the number of blinks from 0 to 33). When the indicator lights for 1.3 seconds
it is equivalent to ten blinks. For example, a 1.3 second illumination and two blinks (0.5 second X 2) of the indicator
equals 12 blinks. Follow code 12 troubleshooting (page 5-24).
• When more than one fai lure occurs, the MIL shows the blinks in the order of lowest number to highest number. For
example; if the indicator blinks once, then two t imes, two failures have occurred. Follow codes 1 (page 5-14) and 2 (page
5-16) troubleshooting.
