Q45 parts wanted

[tattoopops]

Hi, I was wondering if anyone has any tips on where I can find used parts for my Q. I am looking for a lot of miscellaneous stuff such as power antenna, original stereo equipment, interior stuff, ect. Does anyone part these cars out? Please let me know. Thank you, John

There's many of us, me included, that have 94-96 parts for your car and a lot of it can probably come from a 90-93Q (i.e. antenna). If you can't find what you need in the Infiniti Parts For Sale forum start up your own thread there with specifics on what you need and owners will come out of the woodwork with what they've got.

What color interior/exterior is your Q?

I have a couple of 1994-1996 Q45 parts, check out the list in my signature.

I think he means Traction Control System (TCS) Control Unit, Not a ABS computer which is mounted inside the dash on the passenger side.

It is?Hahaha well this one says ABS on it.IDK well I got two computers that's all I can remember.

You pulled it from the trunk though right?

Where does the service manual say the TCS Control Unit is located...Trunk right?

The Transmission Control Unit is the 64U75 (1993 Q45 First gear start), Should have sold by now to a 1990-1992 Q45 owner.

My TCS light is on...Could that have anything to do with my transmission issues?

is your slip light also on?

[Infinitiguy19]

Well if its the Main Throttle Position Sensor thats not set correctly then yes. But other than that I doubt it but I don't have many years of experience under my belt.

I would check the two relays near the metal battery tray as they are more prone to failing than anything else. Be careful with the metal brackets holding them in place as they are old and fragile.

Yes, my slip light is on.....I LOVE THIS FORUM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hi everyone, in my 95 Q the "slip", "tcs", and äbs"lights r staying on and have been that way since I purchased the car a couple of months ago. I was wondering if anyone has any info or advice on how I should approach dealing with it? Also, could any of these lights affect the performance of transmission shifting? Finally, could a tps affect the timing of transmission shifting? Thank you very much!!! John

Check out the service manual: http://www.nicoclub.com/FSM/Q45/1995_Q4 ... Q45/br.pdf

A mis-set Throttle Position Sensor could indeed affect when the transmission shifts.

You need to either take your car somewhere that has a real Nissan Consult 1 or 2 (Nissan/Infiniti dealer, Nissan 300ZX specialty shop...). Or put the car on a dyno or a lift and bring it up to 30 MPH for one minute. Then by doing the latter the TCS OFF and SLIP light should flash along with the LED on the Traction Control Unit in the trunk.

Check the Throttle Position Sensor first and make sure its set at .44 volts when the engine temperature is 176*F and above. Best done when ambient temperature is warm/hot because the coolant temperature sensor might not be as accurate as it was when new. And that means that the Fast Idle Cam will hold the throttle open just a little but enough to mess up the TPS reading. So don't try and set the TPS when its cold out and make sure you move the TPS very slowly to set it correctly.

Also make sure that the TPS is functioning correctly by using a analog Volt Ohm Meter and seeing if there are any "Dead spots" when Turing the TPS all the way from lowest voltage to the highest. Basically make sure the analog VOM needle moves smoothly.

If the above doesn't work out for you I think I may have a spare.
