Pgm-Fi Self-Diagnosis Malfunction Indicator Lamp (Mil) Failure Codes - Honda CBR954RR 2002 Service Manual

FUEL SYSTEM (Programmed
PGM-FI SELF-DIAGNOSIS MALFUNCTION INDICATOR LAMP (MIL)
FAILURE CODES
The PGM-FI malfunction indicator lamp (MIL) denotes the failure codes (the number of blinks from 0 t o 35). The MIL has
t w o types of blinks, a long blink and short blink. The long blink lasts for 1.3 seconds, the short blink lasts for 0.5 seconds.
When t w o long blinks occur, and one short blink, that problem code is 21 (two long blinks
blink). Then, go t o the flow chart and see problem code 21.
When the Engine Control Module (ECM) stores some failure codes, the MIL shows the failure codes in the order from the
lowest number t o highest number. For example, when the MIL blinks once, then blinks seven times, t w o failures have
occurred. Follow the flow chart for failure codes 1 and 7.
