So I confirmed I have the same problem.

I will try to see if the ECU cuts the ground at a certain RPM, while stationary.

I drove my car pretty hard yesterday with the AC on, and it seems to have been fine. But, I never went above 80% throttle, and I never redlined it. So, it be nice too see if WOT or redline or both causes the ECU to cut AC RLY.

The FSM does not cover this subject AFAIK. Also, ACPDCUT does NOT do anything as far as I can tell. I had a meter on this wire while driving, checked at WOT, redline, key off, etc. It never changed state. (I think it stayed at GND the entire time).

My best guess at this time: Maybe the ECU is not happy to see a constant voltage on the AC pressure sensor input. The problem with this theory is that even if I go WOT/redline with the AC off, when I go to turn the AC on the AC RLY is still disabled.

I bought a OBD-II scanner that shows live data, and unfortunately the scanner does not show everything a CONSULT-II would show. You'd think if the ECU had a reason to shut off the AC RLY output there might be a code or some value you could see.

Here's a link to a thread I started about this subject, maybe we can get this figured out: http://forums.maxima.org/all-motor/5...yone-else.html

So it seems like the compressor is cut right before 6k RPMs. I only tried stationary revving while my friend was watching the ac clutch. I wonder if using a different resistor(besides the single 100K ohm resistor I used) ie. inputting a different voltage into the white signal wire, will move the Cut point to a different RPM, ie higher RPM. But then the AC Cut won't be proactive, but more reactive (if the cut was in lets say 7k or 8k RPMs) making it a pointless precautionary measure.

On a different topic, I had a guy with a Consult computer reset my flashing Air Bag light. Now it stays off. I'm soo pleased. Only thing now is the damn ABS light. He checked the ABS system as well, and told me everything checks out fine. I know for a fact the ABS system is fully operational(tested on road with some light sand). The SILA wires (L/R) are the ones that are supposed to be connected, correct?

'98 ABS Control Unit - pin 30 (L/R) (runs to the guage cluster which can be easily accessed from the connector that goes the the guage cluster - M82 pin 11) --> '03 guage cluster - M33 pin 10 (L/R) ???

I see only ONE wire going to the guage cluster on the '98. But there are TWO wires regarding ABS that run to the guage cluster in the '03. Both guage clusters have "SILA" input in common (w/e that is). Does the '03 guage cluster M33 pin 15 need to see anything to turn the ABS light off?

I know if I ground '03 M33 pin 10 or 15(cant remember which one) the ABS light is turned off. But it is turned off permanently, it doesn't even turn on when you turn the Ignition Key to the ON position(when all the guage lights turn on).

What to do to have a functional ABS light?

I may be wrong, but as I'm putting this altogether pin 15 from the 03 cluster is the signal that comes from the ABS control unit that tells the speed of the car. And then the cluster sends that signal to the ECM through pin 32.

So if I'm putting this altogether properly wouldn't you have your VSS connected to pin 15 of the cluster? And then your ABS SILA would only be connected to pin 10.

Please correct me if I'm wrong.

What is M161/ F68 pin 10 (R) used for? I had it teed off from the VSS signal and to the guage cluster pin 15.

iTrader: (6)

Well I spent an hour and a half last night trying to find M161/F68 pin 10 and I could not find it for the life of me. I don't have a clue as to what it's for. In fact, of the 18 pin locations in those connectors there was only one I couldn't find and it was pin 10. So I am not sure how to help you. Do you know where you found info for pin 10?


Also one question I have, I can just use a double pole relay from a 4th gen correct? I just replace the old ECM relay with the new 2 pole and then use the old 1 pole for the throttle motor correct?

goldtooth

iTrader: (56)

I believe you replace the old ECM relay which is a 4 pin BLUE one with a 6 pin BROWN one. Then you use a 4 pin BLUE relay for the throttle motor relay.

How do I go about wiring up the Cruise Control?

hacim105

iTrader: (6)

I think depending on how you made you're wiring connections, I think you have two options. You can either allow the A33B ecm control the cruise control (which I think is the more difficult of the two options) or secondly (this isn't confirmed at this time) but you could splice a wire into A33B connector M32 pin 32 and run that into the speed sensor pin of the ASCD Control unit on the A32. For a '96 it's connector M30 pin 7.


Edit: My bad, I forgot a vital point for the A32 ASCD to work is the necessity of a cable driven system, which is being done away with. If only there was an output from the ASCD, wiring up the cruise control would be so much easier.

iTrader: (7)

Only the A33B ECM can perform cruise control on a full swap.

You need to add resistors to the steering wheel controls and also the cruise main, wire them all up in parallel/series per 02+ FSM, and connect the two wires from the ECM to your modified circuit.

It's a bit tricky because the 02+ have all switches on the steering wheel which have resistors and operate as a voltage divider and only two wires connecting the entire deal, but our A32's have two seperate switches that are setup for regular circuit open/close function. So you have to be creative to mod it to incorporate resistors.

Sorry, I don't have a schematic example. Maybe I'll put one up later.

Wow, if someone tells me what to do or at least try step by step, I would be forever grateful. I really have no clue as what to do unless someone explains it to me in lamens terms...

spoonfeeder

Here are some pictures of the marked up wiring diagrams and photos I made when I adapted the 4G cruise controls.

I opened up the steering wheel control and removed the two diodes and the resistor. I cut the trace on the back of the control to terminal 3. I then soldered in a couple of jumpers to tie terminal 3 to the cancel switch and also one to replace the resistor that was removed.
Three resistor groups were then soldered in (its a tight squeeze)

The rest involves intercepting the wires coming from the spiral cable to the original main cruise switch on the dash and tying them back to the ecu.

Is there a particular resistor that should be used to get this to work properly?

Edit: ok I don't really buy resistors, I got the fact that I need one 2520, 250, 820, and 410 ohm resistors but is there a particular wattage I should be looking for? Or does that not matter?

I also have a question about the O2 sensors. Do I need to use O2 sensors from an A33 or will the A32 sensors suffice?

And are the sensors before the precats sensors 1 or sensors 2?

On my data link connector M28 (A33B), I have 8 wires coming from it but I've looked far and wide through the FSM and it only shows 6 wires coming from it total. The extra wires far from pins 9, 12 & 13. I cannot find any info from these pins anywhere. Does anyone have a clue what they are used for? (and I have no clue where the originate from seeing as I've already mutilated the harness. I'm trying to get everything together but I'm in total confusion with this)

Also, do I need to use O2 sensors from an A33b or will the A32 sensors suffice?

And are the sensors before the precats sensors 1 or sensors 2?

goldtooth

iTrader: (56)

You need the sensors from A33B because the A32 have different connectors.

iTrader: (7)

12 and 13 are for the TCM CAN comms. Do you have a MT or AT trans? If MT or A32 AT, they are not connected. Only the A33B AT uses these. And without the Consult-II, no GST can access them anyways.

hacim105

iTrader: (6)

Thanks, I was finally able to find it all. As you said 12 & 13 connect to the TCM. And then I found 9 connects to the ABS/TCS Control Unit. All of which I don't have any need for. So I'll just cut them off and forget about them.

From what I can tell by looking at the FSM the 03 Maxima/ 03 Altima share the same ECU.. Can someone please verify for me before I go spend the cash that the engine harness from an 03 3.5 Altima will work with my 03 Maxima ECU?

iTrader: (26)

They have the same pinouts and harness configuration/connectors. There may be differences where it connects to the dash and engine room harnesses though. You'd have to look through EC and EL to find those out.

KRRZ350

iTrader: (29)

So what's the reason for the gauge cluster being a requirement? Is it because the a33b's ecu has a different tach output, or is it because the power for the VSS runs through the cluster first before going to the ecu and tcm?

Because you can run an a33b without the VSS power going through the cluster, and afaik both 6-mt's and ref04b trannies have an unused spot for the 4th gen VSS which could be used to retain the 4th gen speedo and odometer, whether or not either a33b trans option has the actual drive gear on the dif for the vss I can't confirm yet though.

KRRZ350

iTrader: (29)

What was I thinking, the 6mt I just picked up has a temp plastic cap put there by the tech who pulled it, however I'm still geussing that the 6-speed vss is the same as that of the 4th gen, considering it appears that nissan used a nice universal signal for all of them apparantly, I'm basing that off of the fact that the a/t 3.5's have a three-wire revolution sensor in place of a revolution sensor and vss like on the 4th gen's, as well as xxxxxx getting the 4th gen vss to work on a 3.5 swap w/ref04a/v in place of the ref04b & three wire revolution sensor. Also the FSM's don't have the pulse charts of all of them, but the signals at ?? and 19mph appear to be the same.

If this makes sense to anyone other than myself that's awesome, but in a nutshell it appears that you don't NEED a 5.5 cluster (You would WANT it if the ecu tach outputs are different) and it also appears (to me, at this point in time, not definite) that with the interchangeabilty of VSS and Revolution sensor signals that you can run any VQ trannsmission (and even VE for the turd gens out there) you want and still retain a working 4th gen speedo and odo.

The VSS output from the A33B cluster has (at least) at different frequency than that of the A32 cluster. When eng92 used an A33B cluster with A32 ECU he ran into a soft speed limiter around 80. When Jime used the opposite setup, his throttle never opened 100%. eng92's findings are that the A33B VSS output frequency is higher than the A32's by a factor of 4.
