Need help diagnosing SLS chime on lifted ’99 Discovery 2
Hey everyone,
I just picked up a 1999 Discovery 2 (gas, LHD) and I’m chasing an SLS chime issue that kicks in right around 15 mph. I’ve searched through a bunch of older threads, checked the usual suspects, and wanted to sanity-check what I’m seeing before I start pulling relays or doing a coil conversion.
Here’s what’s happening:
The truck is lifted (looks like a mild suspension lift from the previous owner).
The chime only starts once I’m moving ~15 mph, never at idle.
Hitting the SLS raise button did silence it once, but hasn’t worked since.
No sagging overnight. Both airbags hold pressure and sit level.
No warning lights on the dash.
HDC is off, and the truck is definitely in High Range.
Assume it’s an SLS height sensor / calibration issue based on what I’ve read.
I know the lift can throw off the sensor geometry, so my question is:
Before I pull the R5 relay to stop the chime, is there anything else inside the cabin or SLS-related that I should check or reset on a lifted D2?
(Already checked the sensor linkages but they look intact. Haven’t recalibrated yet because I need to track down a Nanocom or Hawkeye.)
Any insight appreciated. Not trying to ask a lazy question—just want to make sure I’m not overlooking something obvious before I disable the system or schedule a recalibration.
