The vgrs has a self reset feature. The fact that it hasn't reset (recentered the steering wheel) itself would support a genuine issue. I'm thinking the blown resistor is in the car and not the Arnott cap. If the new caps don't allow you to remove the error code/light, I'd explore this theory.

 

Thanks for all of the information and suggestions. I need to put this project "ON HOLD" until September 16 due to work projects.

Talk to all of you later!

Well, after a 2,000 mile trip with NO problems I am still dealing with error codes. Alignment was completed at GM dealer (works on all cars) using the HUNTER system - new model last year. The dealer DOES have Toyota compatible scan tools but can NOT eliminate the codes. It indicates a C1289 error. Apparently I will have to work with Lexus dealer to resolve issue. OR I CAN IGNORE CODES AND KEEP DRIVING. Oh well..........

 

Glad they are working well. So, the alignment solved the steering centering? Ignoring the codes is a good option. This info will be useful to the forum.

 

Steering and steering centering are now perfect. I will see the Lexus dealer for oil change service Spring 2024 (100 miles away) and will see if they can reset the code for a reasonable $$. Thanks to all for comments.

 

Glad to hear the Arnotts held up well on your trip! What OEM drive mode would you say the Arnotts are comparable to?

 

Do the Arnotts actually adjust up and down or soft and firm? Without the sensor on top, I'm curious if they do.

 

1. It's not a sensor. 2. They do not.

 

I thought so. I was puzzled why he was happy with their performance as they don't adjust. If saving money was the main point, switching to standard struts would be less problematic.

 

Comfort Mode - 460 is used mostly for trips 100 miles plus. Disabled adult in rear seats.

 

good point! If they don’t self adjust up/down, I don’t see the point of using Arnotts, unless having air suspension is an absolute must.

 

They somewhat adjust up/down but no dampening force adjust. swfla, my thoughts exactly. At least springs look clean and tidy. arnots (lowercase a) look like something out of a steampunk fantasy.

 

The VGRS and stability systems should be linked to the shock damping, not the air ride part. For instance, if the car detects yaw or excessive slip angle, it would stiffen the shocks to help keep the car under control.

The air springs can't be adjusted fast enough to be useful in a dynamic driving situation.

Unfortunately, the variable dampers and the air springs are married together/inseparable in the OEM design, which is why they are so expensive. And I don't think the variable dampers are KYB like the base struts are. We have 2 LS460s, and the one with KYBs just passed 119,000 miles and the shocks are still perfect. The air spring one only has 89k but has failed 2 under warranty and a 3rd is sagging when it sits for more than a few weeks - and that car has never seen salt (stored in a heated garage in winter).

 

Interesting theory.

 

Well, a long time coming... Drove the past year with NO problems except the CODES mentioned earlier. Just had a local shop (Service manager is LEXUS trained from a few years ago). He performed a 4 wheel alignment and for some unknow why, the error codes were able to be cleared. 300 miles this week and all is well. MAGIC?? My mileage is at 79K...
