INFINITIEXPERT
RECOMMENDATIONS
One of the most common reasons the
engine light comes on, is due to a loose gas cap. Make sure the gas cap is
secure then after a few days the light should turn off.
If you would like to
reset the ?Engine Light? (Service Engine Soon? Light) disconnect the car
battery for more than 24 for hours. Why? The back up battery in the Engine
Control Modulo last up to 24 hours only
If after
disconnecting the battery the light is still on you should have a technician
scan for trouble codes present in computer memory. Your vehicle is equipped with
on board diagnostic capabilities. Check Engine light indicates when illuminated,
malfunction has occurred in operating system. Technician with scan tool can
retrieve stored malfunction code (s), this identifies system area requiring
repair.
Remember any technician with a
scan tool can check for codes, you do not have to use a Nissan or Infiniti
Dealer.
