How to Reset the Service Light in an Infiniti I35
by 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.
Step 1
Turn the Infiniti off if it is running. Leave the key in the ignition.
Step 2
Look under the dash and steering wheel and locate the black On-Board Diagnostic (OBD) outlet.
Step 3
Connect an OBD scanner to this port, then turn the scanner on.
Step 4
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.
Step 5
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.
Step 6
Disconnect the scanner, then turn the Infiniti off.
Step 7
Turn the Infiniti back on and look at the instrument panel. The "Service Engine" light should be dark.
