Maxima 86-94 3.0 (SOHC) Y Procedure:
• All except 87, 88 Maxima: Access
ECU (located under passenger seat)
(N5).
• 87, 88 Maxima only: Access ECU
(located behind center console) (N3).
• Turn ignition on. Using Nissan tool,
turn diagnostic mode selector fully
clockwise, wait at least two seconds,
then turn selector fully counterclock-
wise. Observe both red and green
LEDs on ECU for codes.
Codes: Codes are displayed by blinking
of both Red and Green LEDs (N10). The
Red LED blinks first, followed by the
green LED. The Red LED indicates the
first digit (tens); the Green LED indi-
cates the second digit (ones). Example:
one Red flash and two Green flashes =
code 12 (N11).
NX 91-93 1.6, 2.0 Y Procedure: Access ECU (located be-
240SX 91-95 2.4 hind center console) (N3) (except 300ZX,
300ZX 90-95 3.0 (incl. which is located in passenger side foot-
Turbo) well under carpet (N5)). Turn ignition
on. Using Nissan tool, turn diagnostic
mode selector fully clockwise; wait two
seconds, then turn selector fully coun-
terclockwise. Observe red LED on ECU
for codes.
Codes: Codes are displayed using a
combination of long and short blinks.
Codes are determined by the number
and duration of LED blinks. A long
blink indicates the first digit (tens); a
short pause indicates the second digit
(ones) (N8). Example: long blink-pause-
short blink short blink = code 12 (N9).
If more than one code is stored, the
ECU will blink the lowest number code
lowest number code first, pause for two
seconds, then display the next highest
number code. This continues until all
stored codes have been displayed; the
cycle then repeats.
