How to Reset the Service Light in an Infiniti I35by Richard Ristow
An Infiniti's I35's diagnostic system can detect certain problems with the vehicle; when a malfunction occurs, this system issues a fault code. The "Service Engine" light is a result of that fault. Disconnecting a car's battery will sometimes clear a "Service Engine" light, but doing so can also mess up saved settings in other electrical components. In addition, simply shutting off the light means potentially ignoring a problem with the vehicle. The best way to reset the light is by using a diagnostic scanner; this way, you can check the codes first then reset the light.
Turn the Infiniti off if it is running. Leave the key in the ignition.
Look under the dash and steering wheel and locate the black On-Board Diagnostic (OBD) outlet.
Connect an OBD scanner to this port, then turn the scanner on.
Turn the key in ignition to will start the Infiniti's diagnostic system. It may take a few seconds before data flows from the Infiniti to the scanner.
Note the fault code, then clear the system once the fault code shows on the scanner's screen. While the orientation and configuration of scanners vary by brand, there should be a dedicated "Clear" button.
Disconnect the scanner, then turn the Infiniti off.
Turn the Infiniti back on and look at the instrument panel. The "Service Engine" light should be dark.
