Misfire and Fuel System Malfunctions:
For misfire or fuel system malfunctions, the MIL may be eliminated
if the same fault does not reoccur during monitoring in three subsequent
sequential driving cycles in which conditions are similar to those under
which the malfunction was first detected.
|
• |
All Other Malfunctions:
For all other faults, the MIL may be extinguished after three
subsequent sequential driving cycles during which the monitoring system
responsible for illuminating the MIL functions without detecting the
malfunction and if no other malfunction has been identified that would
independently illuminate the MIL according to the requirements outlined
above.
