Infiniti Check Engine Codes (credit to Nicoclub.com/Nick Zluticky)
NOTE : There were 2 ways of doing this (both by C4nitrousboi and Lonewolf317)
Got this off nicoclub.com, it has codes 11 and up.
I’mma gonna put code 10 as from the tranny solenoid problem.
How to Check Codes
Without OBD II
On G20 models, the ECU is located behind the center console. On J30, M30 and Q45 models, the ECU is located behind the RH kick panel.
If a malfunction occurs within the ECU/fuel injection system, a diagnostic trouble code may be stored in the ECU and the 荘Check Engine鋳 lamp will blink. There is also a lamp built into the ECU which will concurrently blink. To read Code output, proceed as follows:
Turn ignition On, but do not start engine.
Using a small screwdriver, turn diagnostic mode selector switch, located on side of ECU, fully clockwise.
Wait two seconds, then rotate switch to full counterclockwise position.
A malfunction code can be read as the long (0.6 second) blink, indicating the first digit of a two digit number and the short (0.3 second) blink, indicating the second digit.
Ensure that the diagnostic switch is to the full counterclockwise position whenever the vehicle is in use.
w/OBD II
On G20 and I30 models, connect a suitable Scan Tool to the DLC, located under instrument panel fuse box cover.
Clearing Codes
If using a scan tool, follow tool manufacturer痴 instructions to clear Codes.
A second, though more time consuming method of clearing codes involves using a small screwdriver to turn the diagnostic mode selector switch, located on the side of the ECM/ECU, fully clockwise. After waiting two seconds, rotate the switch to the full counterclockwise position. The diagnosis will end and memory will then be cleared.
