There's a calibration procedure in VIDA for setting the level. As REM is the interface to the level sensor and you installed a new REM, I wonder if a calibration might be in order.

 

No new parts or calibration has been done in this regard.

Wait a moment…. Are you saying the headlamp leveling calibration goes through the Rear Electronic Module that was just replaced? For sure?

I am ignorant of these procedures and dealing with the body shop that wants no part of it unless OKed by insurance company first.

Thanks I appreciate your insights and detail.

That arm positioning doesn’t seem right to me, you know?

Thank you very much, that confirms….

I still want to know if that sensor actuating arm appears to be positioned correctly, given the suspension is hanging in a fully down position, or does the arm travel in much less of an arc than I am imagining?

Cheers,

Vehicle flat on ground in these photos (long arms). Bottom mounting point is welded, the link is of fixed length. Check the sensor mounting from the front, see if it looks like mine. If it's crooked, then you have an issue.

 

Many thanks.. These details are are really helpful.

In addition to the above advice & assistance, I came up with a related thought this morning having to do with the recent Rear Electronic Module replacement and programming.

To address the dashboard DSTC fault messages: "Park Assist Service Required" & "Anti-Skid Service Required ", a new Rear Electronic Control Module 30728512 was installed & programmed to the car.
All seemed well until we drove the car after dark and found the Active Bi-Xenon lights 'pointing to the ground'.

Recently, I have learned on these pages that the 'self leveling' [HID] function can be turned On/Off using Volvo software. Apologies as I do not know the proper terminology...

That said, I wonder if a brand new Rear Electronic Control Module has the HID leveling functionality turned ON or Activated by default?
Or is it OFF and need to be tailored/programmed to each car's functionality?

I have read that if OFF.. these active lights will point to their lowest possible setting by design...

If the latter............................ here we are.


* If possible, I am really keen on seeing a screenshot of this 'functionality activation' if you know what I mean..
I am a visual learner.. and may need to show / prove the reason for the headlamps malfunctioning as they are currently.

Thanks once again,

M

 

I took a look in VIDA and a couple representative user guides and I'm not aware of the ability to deactivate the ABL leveling.

You can check for yourself- Volvo Car USA Support | Contact us | Help (custhelp.com) , if deactivation is available as a user function it would be in there.

This is very helpful!

Did not find the answer.....

Cause of the condition Identified!

A new Rear Electronic Module requires a Volvo software download: REM Reload 9428285 $99.10
The leveling sensor signal is then processed.... The Active Bi-Xenon lights will then function properly I am told.

If the Rear Electronic Control Module 30728512 was installed & programmed to the car by a dealer as noted above, then why would you be buying a reload of the exact same software?? Makes no sense to me, light leveling is a standard function and is not a value added feature. Was calibration ever attempted?

The original REM unit was diagnosed, deemed faulty and a new replacement was installed and the replacement keyed to my car by an outside 3rd party [for the body shop doing the repairs].
This was not a Volvo specialist, nor a dealership doing the work.

I called a dealership earlier today and was told a new REM must have a download REM Reload for the Active Bi-Xenons to work properly.

As far as calibrating the position sensor for the Bi-Xenons, I do not know what was done. Obviously, if not done here we are...

As I was at the body shop today, the company who did the programming said the REM reload HAD already been done.
There was NO Volvo software download listed as a line item on my repair invoices and/or supplements.. At a retail cost of $99. I would expect to see that listed, ergo all my questions....

I know a lot more about B18 & B20 motors, S.U. carburettors, and early EFI.... As you easily see, I don't know VIDA or any of that so I try to gather what makes sense to me & go forwards, you know?

What you say just now makes perfect sense given if the fellow loaded the REM Reload.. then it is likely the Bi-Xenons leveling calibration is unlikely to have been done...
Or there is another fault as well...

I appreciate your posts on this subject. They have helped.

Appreciate the context, makes sense now.

Thanks

 

I think there's an independent in your area with a lot of Volvo experience who may be able to help...


(Did you know Wally?)

 

Thanks John,

Having discussed this issue with both the insurance Co. & the body shop... I have made an appointment at the body shop for their guy to sort it out once & for all.
He knows what he has done for the REM already, so wouldn't have to start from scratch [as it were].
They & the insurance people appear very keen on getting resolution to this.

I'll know more on Monday afternoon.

UPDATE

I picked up the car yesterday afternoon after the Scan folks were done with it.. I was told the fellow re-calibrated the position sensor [again]...
Was told: "If there were still a problem I should go to the dealership & send the insurance Co. the bill.."

Last night, after dark, we went out on a road test....
Headlights are A-OK now, just as they were before the body repairs..

This image from post 4 I included in my emails to insurance company and printed up to give to the body shop.... absolutely saved the day.

By that, I mean the customer, the insurance company, the body shop, and the outside automotive computer service were all on the same page.
This brought clear results so many thanks to all who advised/assisted.

My C70 has similar issues, the low beam is way too low. I was looking into the calibration procedure and found that both the front and rear suspension height sensors are both to be between 2 and 4 volts. The car needs to be level too. However my front suspension reads around 1.6 volts. The calibration went ahead with no change to the light angle, so was thinking of altering the voltages by adjustment to trick the lights into thinking they need to come up a bit higher.
