3" Lift in GU9 = Traction Control and ABS Issues not experienced in GU8 wit Same Lift

[Brad_GU9]

Hi All My first question to the group please........

Apologies for the long title but after searching previous threads and not really finding any suggestions other than a faulty Brake Fuse? to possibly be the culprit I thought I would ask if anyone can shed some light please on a couple of issues I have with my new GU9.

I have just upgraded to the series 9 from my series 8 and transferred the exact same suspension including coils, shocks, extended sway bar links, adjustable panhard rods, poly air bags, adjustable steering link etc. to the series 9. It is a 3" Lift which gave me no trouble at all in the series 8 for the past 3 years or 80,000klms.

2 Issues I am having now are:

Issue 1 - when cornering even slightly faster than your grandmother would the traction control/VDC system thinks the vehicle is out of control
which it definitely is not and is disconnecting the throttle.

Issue 2 - When braking down hill around corners again the electronics for some reason think I need additional braking and in once instance on the weekend the application of the unexpected additional braking to what felt like only the front right wheel sent the vehicle to the right unexpectedly toward oncoming traffic.

I have discussed the issue with the dealer who says none of the sensors that monitor the VDC or Traction Control are programmable therefore they cannot offer any fix as they claim everything is preset from the factory and cannot be altered or have its sensitivity adjusted etc. I talked to Nissan Customer Care who can't do anything either because the problem only occurred after I modified the suspension.

My mechanic seems to think the issue might be over excited yaw sensor or what he is calling a gravity or G sensor which apparently is located under the rear seats somewhere. I have discussed the problem with a few 4WD heads and seems that locating the gravity sensor and lowering it 3" might help but if when I find it, it is located on the floor this could be difficult.

Given the same suspension proved itself in the series 8 there is something new or different in the series 9 that is causing these problems.

Has anyone else had these issues and if so I would absolutely love to know how you fixed them because whilst I am aware of the vehicles behavioural issues and can anticipate what it's going to do I am concerned that right now if anyone else decided to drive it's actually quite dangerous.

Thanks Brad
