Do you have a wheel fitment template so I can check the clearance on my BBS RG-Rs? I've had trouble in the past with another kit that was "guaranteed" to fit.

The door triggers themselves are also wired to the BCM, so you need to be careful you don't short something out and ruin the BCM.

Airbag connectors are yellow, to distinguish them from everything else. The white connector could be for the seatbelt latch. How many pins does it have?

If you're really a man's man, you wouldn't even ask the question. Just keep driving and see if something breaks.

Low brake fluid turns on the EML? What code does it throw?

Attached are the instructions from the US Service Manual. Inside Mirror.pdf

Generally the traction control system likes to see the rear tires about 2% larger in diameter than the fronts. However, I know several people who have driven their cars with no stagger. Are you seeing the traction control intervene as you drive?

kkong6, The diagram you posted is for the earlier VQ33s without variable exhaust valve timing. I recommend you visit this web site: http://www.nicoclub.com/archives/nissan-350z-factory-service-manuals.html and download a complete service manual. While the manuals are for US spec cars, the differences in you case will be negligible.

The following is based on the US Nissan 350Z Service Manual: There are two cam sensors at the rear of each bank of cylinders. The inboard sensors, behind the inlet camshafts, are called the camshaft position sensors (phase) by Nissan. The outboard sensors, behind the exhaust camshafts are the exhaust valve timing control position sensors. The sensors themselves are all identical. Your problem could be with either the position sensor or the timing control sensor in bank 1.

The stock fans are either both off, both on at low speed, or both on at high speed. Fan speed is determined by coolant temperature, air con ON or OFF, and air con refrigerant pressure. As I read the writeup referenced above, with the Mishimoto setup both will be off, one will be on (corresponding to stock fans on low), or both will be on (corresponding to stock fans on high).

You can check if you have TPMS a couple of ways. First, look at the valve stems on the tires. If they are rubber, you don't have TPMS. If they are metal, you probably do. Second, look for the low pressure warning light to come on briefly when you first turn the ignition key on. If it doesn't come on you either don't have the system or the LED is bad. On US spec cars the warning light should come on when any tire drops below 28 psi (1.94 bar).

TPMS has been available on US spec Zs since the car was introduced in 2003. Initially the system had its own control unit with its own fuse, but in 2005 the TPMS was integrated into the Remote Keyless Entry system, so pulling the fuse disables the remote lock and unlock functions. The answer to the OP's original question is yes, when you put the original wheels with the original sensors back in their original positions, the light will go out. When the system cannot detect one or more sensors it declares a fault and illuminates the warning light. On US cars prior to model year 2007, individual tire pressures could be read on the trip computer. For whatever reason, Nissan deletes this function in model year 2007, an absolutely stupid move.

In US models up through model year 2006, tire pressures could be read on the trip meter. Beginning with model year 2007 Nissan removed the pressure readout and went strictly with the idiot light.

The TPMS sensors are attached to the inflation valve stem. Chromatic, The last time I checked, the sensors themselves cost around $60 US each. You need to demount the tire to change one, then activate it so the system recognizes it. The cost your dealer quoted is a bit high unless his labor rate is through the roof. The blinking pattern of the TPMS light will tell you which sensor is faulty. It's probably just a low sensor battery, but the sensors are sealed so replacing just the battery requires some surgery, It's been done, but I don't have a link to the procedure.

The procedure described in the video only works if the discrepancy that caused the flashing AIR BAG light has been repaired or is intermittent and not currently active. Active faults cannot be reset. Some OBD scan tools can read SRS faults. If the light will not reset and you don't have access to such a scan tool, you will probably have to go to your Nissan dealer to have the system chjecked and repaired.

With each new model year, Nissan added additional codes. I suspect the list from a 2009 model would be the most complete.

On US cars there's a threaded hole in the rear floor on each side where you can attach a child's car seat top tether strap.

The Sparco bars don't have the vertical posts that bolt to the bottom seatbelt bolt holes. I purchased one in 2006 and it only included the cross bar. All the pictures you see online are generic. And there were fitment problems with 2005 and later Zs where the seatbelt shoulder mount had been redesigned from earlier models.

Glad you solved your problem. I wasn't aware that IMPD E/R relays were individually replaceable. Here in the USA Nissan doesn't sell individual relays. They only sell the complete IPDM E/R unit.

Unfortunately, UK customers don't have access to their Service Manuals. However, you can download a USA-spec manual at http://www.nicoclub.com/archives/use-nicoclub-coms-factory-service-manual-database.html. Except for country-specific items, I believe the basic electronics are the same. Look in the ec.pdf section for descriptions of trouble codes and diagnostic procedures. I don't think the relays on the IPDM E/R are removable, so your troubleshooting will have to be done at the connectors.

P1126 indicates that there is an open circuit in the throttle control motor relay circuit. That fault will also cause P1122, Electric Throttle Control Function. The problem could be with the relay itself or in the wiring harness or connectors. If it is the relay, the relay in question is part of the IPDM E/R, located near the battery. Unfortunately, the relays on this unit are non-replaceable; Nissan wants you to replace the entire assembly, and they aren't cheap.

It appears that something mechanical broke in the steering linkage, causing the steering wheel to turn to the left. The ESP and SLIP lights are caused by a disagreement between the steering angle sensor (attached to the steering wheel) and the yaw rate sensor. The steering angle sensor indicates a left turn, but the yaw rate sensor says straight ahead. When the mechanical problem with the steering is fixed, the ESP problems should disappear. Your mechanical problems could include loose or broken U-joints on the steering shaft, a damaged steering rack, a loose or broken tie rod end, or a problem with either steering knuckle. You or your mechanic need to give the entire steering assembly a thorough inspection.

peteman35, Which harness bar is pictured?

Correct. All US models have TPMS. From 2003 through 2006 the tire pressures could be read on the trip computer display in the center gauge cluster. Beginning with the 2007 model year, the actual tire pressure display was removed and only the idiot light was available to advise the driver of any problem.

Matt, Here are the pages from my 2005 Service Manual that describe the airbag modes and blinking patterns. Airbag Diagnosis (2005 350Z).pdf
