04 Navi No Start-No Crank No PWR to OBD

[stamp11127]

The black diamond triangles usually contain letters. What letters are in the triangles on 71-5?

Check fuse for main light switch - can't make out the fuse number. If it is good and powered check for voltage out on pin 12? with light in park position and again with headlights on. If power is present check for voltage at illumination dimmer pin 2.

I almost gave you that letter, since it was the only letter. The letter inside the arrow is " H " with respect to the diagram 71-1.

The main light switch fuse is: #6

In 71-5, the letters in the up-arrows from left to right are "F", "K", "H", down-arrow end right "L"

In 71-5, the items that currently function are: Clock, traction control switch turns off/on, adjustable pedals.

4WD switch N/A as its a 2WD.

RESULTS:

Fuse #6 has power

Pin 12 has power, in park and in headlight positions

Pin 2 has no power

Diagram 71-4 see splice between main light switch and dimmer switch at bottom of page, looks like s124. There will be a diagram locating each splice by number. Check the splice for power with key in run position.

Here is a closer look at that area. I think s124 is S224, that I circled in red, yes? I am not sure what signifies a splice in this diagram. My lack of knowledge is showing, can direct me to where the diagram directs me to the "splices"? Thx!

I looked at the 2003 Navi diagrams and 17-4 is the same as the 2004. The program lists all the diagrams that have s224 on them but not the location. So that means you have to follow the wire until you find it. Or you could use a jumper wire to put power on pin 2 - connector c2065b with the main light switch off. You may want to have a fuse or circuit breaker inline with the jumper if you are coming from the battery. Then see if your dash lights are on. If not check for power at c2065a pin 4 with the jumper in place. You may need to adjust the dimmer switch to get a reading.

This is how your pdf's should look when printed:

 

[03NavigatorGuy]

Okay, I will take a look as see how hard it will be to trace, no doubt a PITA!

Sorry for the quality of my PDF's etc. They look okay on ALLDATA, but when I convert to PDF's they loose significant quality, not sure if this is something ALLDATA does or what, but I have tried multiple things to try and improve their quality, but to no avail.

If you are printing as a pdf they are using a setting that bitmaps the image to keep you from providing others with a good copy.

I jumped to pin #2 and got interior illumination with all that is to be illuminated EXCEPT for the cluster!

 

[stamp11127]

Anything on pin 4 of c2065a with the jumper in place?

 

[03NavigatorGuy]

Anything on pin 4 of c2065a with the jumper in place?

Yes that is power with the jumper to pin #4 and you can increase/decrease the power with the dimmer switch.

 

[stamp11127]

Jumper should stay on pin 2 then see if there is power coming out of the dimmer on pin 4.

 

[03NavigatorGuy]

Sorry, I meant jumper to pin #2, with power coming out of pin #4

Time to pull the cluster so that you have access to the plugs in the back.
Jumper in place, check for power at:
c220a pin 12
c220a pin 15 ign switch in "run" - see diagram 60-5

c220a pin 15 ign switch in "run" - see diagram 60-5

Pin 12 has power and pin 15 has power with key on AND with key OFF for some reason.

Have you checked the grounds? They are usually located behind the driver and passenger kick panels. Since your air bag light is on that means at least one of the grounds is good.

Another thing to check are the bulbs in the cluster - are they there, good etc?

 

[03NavigatorGuy]

Have you checked the grounds? They are usually located behind the driver and passenger kick panels.

Oh yes, that's the first thing I did. They all 'looked" good, but I still disconnected them, wire brushed them, and tightened them back on.

 

[stamp11127]

Can't go by looks - can't see breaks inside the insulation.

With the park/headlights on are the radio lights on also and will the dimmer switch work on them?

The illumination circuit runs through the instrument cluster. If everything after the cluster works as it should then the problem is with the cluster.

 

[03NavigatorGuy]

I hear you. How do I check them properly?

 

[stamp11127]

Grounds - disconnect the plug from the cluster, meter to continuity setting, one lead to ground wire in the plug the other to the ground point at the other end of the wire.

Lighting would need to use the jumper as before to power the circuit. You probably have a bad splice.

What setting do I set the meter to in order to get the continuity reading?
