Hello, I am new to this forum, thought I share something nice with all of you, the INFINITI service/secret menu instructions work on the MAXIMA

Here are some screens:

(thanks for the pic carcus)
this is what we could of had to make all these icons work:

"Motorola (NYSE:MOT) announced today it has teamed up with Nissan Motor Corporation U.S.A. to introduce the Infiniti Communicator, an in-vehicle communications system (IVCS) available in 1998.5 Infiniti Q45 and I30 luxury sedans, beginning in March"

makes me think even more our screen was to be used also in some Infinitis.

this is why the self-diagnostic asks if you hace IVCS (answer no) and why we have so many unused icons.

The code 25 you saw says your sunload sensor was not working or else it could be you were doing this in the dark. You should get a code 20 if the first test is o.k. During the next test a code 30 should appear if everything is o.k. During the next series of tests codes 41-46 will appear as all the air blend doors are checked.

The IVCS stands for in vehicle communication system or cell phone. You should probably answer no to this and no to sat if you don't have satellite radio.

For those who don't know to get into Self-Diagnostics for non-navi cars:
1. Start engine
2. Turn off Radio
3. While holding down pause/mute button turn volume control in either cw or ccw direction for at least 30 notches. A beep will then be heard. You use the joystick button and Prev buttons to get around.

think i found it. this is what we could of had to make all these icons work:

I have this in my 99 i30...it has onstar-like buttons near the rearview mirror (emergency, info, etc) and steering wheel controls on the left side (opposite of cruise) for speed dial, send/end and volume. According to the dealership when i asked them about this, the cell phone service ended like a year after it started and was "one of infiniti's biggest mistakes" (dealer's words not mine)...oh well guess there's no hope for this in the 6th gen. It would be pretty sweet though

under PARTS: blank adj. it's set at 10 with a range from 5-15. The 10 refers to the number of seconds a screen stays up before going back to where it was before you entered it.

As promised here is a simplified version of the A/C self-diagnostics that is much easier to understand than what I posted earlier.

A. Enter HVAC Self-Diagnostics Mode
1. Turn ignition switch to “ON”.
2. Within 10 seconds after starting engine
press “OFF” switch for at least 5 seconds.

B. Step B Does code #20 appear on the display 25 seconds after 2 appears in the right side of screen?
IF Yes GO TO Step C.
IF No GO TO Step M.

C. Check operation of temp switch
1. Press top of driver side temperature switch
2. Does the temperature switch advance to self-diagnosis Step C?
IF Yes GO TO Step D.
IF No you have a malfunctioning temperature switch.
Replace A/C switch.

D. Check to return to self-diag Step B
1.Press bottom of driver side temperature switch.
2.Does the temperature switch return to self-diagnosis Step B?
If Yes GO TO Step E.
If No you have a malfunctioning temperature switch.
Replace A/C switch.

E: Mode Door And Intake Door Positions Checked
1. Press top of driver side temperature switch.
2. Does code #30 appear on the display 50 seconds after 3 is displayed in right side of screen?
If Yes GO TO Step F.
If No GO TO Step N.

F. Check Operation of Actuators
1. Press top of driver side temperature switch.
2. Press DEF switch. Code Numbers. 41-46 will be displayed as each actuator test is being conducted.
Checks must be made by listening to noise and feeling air flow from outlets with your hand,.

G. Check Actuators
IF OK GO TO Step H.
If not OK Air outlet does not change.
Then Go to Mode Door Motor Circuit .
Intake door does not change.
Go to Intake Door Motor Circuit
Blower motor operation is malfunctioning.
Then Go to Blower Motor Circuit
Magnet clutch does not engage.
Go to Magnet Clutch Circuit
Discharge air temperature does not change.
Then Go to Air Mix Door Motor Circuit

H. Temperature of Each Sensor Checked
1. Press top of the driver side temperature switch.
2. IF Code No. 51 appears on the display Go To Step I.

I. Check Ambient Temperature Sensor
Press “DEF” switch one time. Temperature detected by ambient temperature sensor is shown on the display
If temperature on display differs greatly from actual temperature, check sensor circuit first and then inspect sensor.
If OK GO TO Step J.
If Not OK Check ambient sensor circuit

J. Check In Vehicle Sensor
Press “DEF” switch a second time. Temperature detected by in vehicle sensor is shown on the display.
If temperature shown on display differs greatly from actual temperature, check sensor circuit first and then inspect sensor.
If OK GO TO Step K.
If not OK Check In vehicle sensor circuit

K. Check Intake Temperature Sensor
Press “DEF” switch a third time. Temperature detected by intake sensor is shown on the display
If temperature shown on display differs greatly from actual temperature, check sensor circuit first and then inspect sensor.
If OK GO TO Step L.
If not OK Go to intake sensor circuit .

L. Check CAN Communications
1. Press “REC” switch.
2. CAN communication error between unified meter and A/C amp.
and Display Unit or Display Control Unit is detected.
If OK Turn ignition switch “OFF” or “AUTO” switch to “ON”.
The diagnostic procedure is complete.

M. Malfunctioning Sensor Codes
If two or more sensors are bad the corresponding codes blink respectively twice.
Conduct Step B during daylight outside or have a bright light shine on windshield or Code 25 will be indicated even though the sunload sensor is good..

Code No. Sensor Malfunctioning
21 Ambient Temperature Sensor
22 In Vehicle Temperature Sensor
24 Intake Temperature Sensor
25 Sunload Sensor
26 Air Mix Door Motor PBR on driver side
27 Air Mix Door Motor PBR on passenger side

PLEASE DON'T TRY THIS IF YOU ARE NOT SURE HOW TO USE IT. I WILL NOT BE RESPONSIBLE FOR ANY DAMAGE CAUSED BY USING THIS OR ANY ERRORS I MADE IN DOCUMENTING THE PROCEDURE.
