2004 Q45 Cluster LED bulbs missing for ABS/SLIP/VDC/BRAKE

[valq45man]

Does anyone know if I can replace the tiny LED bulbs in an instrument cluster for 2004 Q45 ? Someone apparently thought it was cute to remote these bulbs somehow. I recently bought this car with the understanding that it needed an ABS Control Module. But I'm guessing they got tired of seeing those lights on all time - so they just removed the tiny LED bulbs. No lights - No problems !

Or am I out of luck and need a new cluster ??? Does the dealer have to re-program the odometer ?

Thanks everyone.

If you download the FIELD SERVICE MANUAL you can see the details of the dash. http://www.nicoclub.com/FSM/Q45/2004_Q45/

Well I see the ip fsm - but i don't think it really described the dash warning lights ???
I need to know the color of the SLIP / ABS / VDC off lights - I'm sure the Brake light is RED - and I am assuming the others are orange/yellow as warning lights ???

sorry, yes they are yellow.

OK guys - I got the circuit board repaired today to re-add the ABS/SLIP/VDC/BRAKE LEDs... Now the car appears to be correct with all those lights stay on after I start it. I noticed that the rear brakes look pretty thin (rotors look bad too). Could that possibly be the cause of these lights being on constantly ?

Thanks very much...

Well no answer here so I guess it is back to Infiniti to try and figure out this ABS/VDC/SLIP lights on. The rear brakes were replaced - fluid level is full. Not sure if a wheel sensor or relay would cause the lights to be on from the time the car is started and stay on constantly.

this post may help you... copied from SteveTheTech (very helpful infiniti technician on here)

In all honesty we should spend pages sharing our experiences with slip and vdc lights.

It is well established that the one of the main reasons a low brake fluid dtc but there are several other things that may cause this type of concern.

I would like take a few moments to address some of the most common things I see that will cause re-occurring illumination of the ABS, SLIP, VDC and/or AWD light(s).
-Low Brake Fluid
-Inproper setting of the steering angle sensor
-Communication issue between the throttle position sensor and the abs control unit
-Incorrect wheel speed sensor input signal to the abs control unit (this can either be from a wheel diameter that is not consistent or altered wheel speed sensor normality)

With the exception of the first none of these things are things you can fix yourself without access to the ABS and other control units to retrieve appropriate diagnosis information.

If the abs light and it's friends come on after a run on a dyno once the control unit detects correct wheel speed the lights will go off. Cycling the key will not work. This also works with to reset some older models after wheel speed signal repairs.

Thanks very much. I will post back info once I take it to Infiniti for diagnosis.

I seem to remember when those lights were on it was my MAF. Got a new one...lights went off. But Ididn't know that until I dropped 100 bucks at an indi shop in Texas to get a diagnosis

[valq45man]

Thanks for the reply. Interesting that a MAF would cause those - seems like I would see other problems if it was the MAF. The car runs awesome without any problems at all. Although my brake pedal does feel a little "mushy" (fluid is full) and new rotors/pads. I'll try cleaning it anyway and see if that makes a difference. I don't have a Service Engine Soon light on either...

Never, ever heard of a bad MAF causing those lights to illuminate, only the "check engine" light may illuminate due to a defective MAF.

Just an FYI... I finally got my car back and working. Southwest Infiniti diagnosed the problem as being a bad wheel sensor (front right) and also had to reprogram/calibrate the ICC. About $500 for the work but now my 2004 Q45 is back to awesome.. Still can't believe Infiniti stopped making these great cars...

Thanks to everyone for their input and help !
