ECU continuously monitors engine operation against
preset performance limits. If operation is outside limits,
ECU activates MIL, if equipped, and stores a diagnostic
code in its fault memory. If component or system
returns to proper function, ECU will turn off MIL. If MIL
stays illuminated, it warns customer a fault is currently
happening, and dealer service is required. Upon receipt,
dealer technician can access fault code(s) to help
determine what portion of system is malfunctioning.
Codes are accessed through key switch and displayed
as blinks or fl ashes of MIL. Access codes as follows:
1. Check that battery voltage is above 11 volts.
2. Start with key switch OFF.
3. Turn key switch to ON and OFF, then ON and OFF,
then ON, leaving it on in third sequence. Do not start
engine. Time between sequences must be less than
2.5 seconds.
4. MIL will blink a series of times. Number of times MIL
blinks represents a number in blink code.

End of Code Transmission
5. A sequence of four MIL blinks make up a fault code.
There is a one (1) second pause between blinks of a
fault code. There is a three (3) second pause
between separate fault codes. After fault code(s) are
blinked a two digit 61 is blinked to indicate program
has completed.
a. It's a good idea to write down codes as they
appear, as they may not be in numerical
sequence.
b. Code 61 will always be last code displayed,
indicating end of code transmission. If code 61
appears immediately, no other fault codes are
present.
After problem has been corrected, fault codes may be
cleared by following ECU Reset Procedure.
Fault Code Summary lists fault codes, and what they
correspond to. Diagnostic Code Summary is a list of
individual codes with an explanation of what triggers
them, what symptoms might be expected, and probable
causes.
