Clearing Codes on the G35 and 350ZThere are several ways to clear ECU error codes.

- Scan ToolIf using a scan tool, follow tool manufacturer’s instructions to clear Codes.

- Manual MethodHere is a quick way to reset your ECU. It is also known to clear codes thrown, and turn off the "Service Engine Soon" Light.

Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds. Repeat the following two procedures quickly five times within 5 seconds: Fully depress the accelerator pedal (HARD). Fully release the accelerator pedal. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking. Fully release the accelerator pedal (while the CEL is still blinking) Wait about 10 seconds. Fully depress the accelerator pedal and keep it for more than 10 seconds. Fully release the accelerator pedal (The CEL light will continue to blink). Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.

- With Consult

Turn ignition Off. Connect Consult’the data link connector (DLC), located behind fuse box cover. Turn ignition On. Touch Start. Touch Engine. Perform each diagnostic test mode according to each service procedure.

- Without ConsultTurn ignition On. Turn diagnostic mode selector on ECU fully clockwise and wait until inspection lamps flash. #Number of flashes displayed indicates corresponding mode. Note number of flashes, then immediately turn diagnostic mode selector fully counterclockwise. If ignition is turned Off during diagnosis, in each mode, and then turned back on again after power to the ECU has dropped off completely, diagnosis will automatically return to Mode I. For description of modes, proceed as follows:

(Mode I): with engine stopped, system in bulb check state. with engine running, system in malfunction warning state.

(Mode II): with engine stopped, system in self diagnostic results state. with engine running, system in front O2S monitor state.
