L494 - Parking Aid Not Working. Fault Code B1C30-73 (2E)
Found the parking aid not beeping this evening. The rear camera comes on fine with the guide lines but the sensors aren't doing their job. It was fine about an hour or so before that when I reversed into my driveway earlier. I vaguely remember reading somewhere on the forum that pressing and holding the parking aid button next to the infotainment screen resets it. When I did that the orange vertical bar/light on the button started flashing and I got a message on the screen "parking aid unavailable, contact your dealer". Plugged in my IIDTool and the fault is:
I cleared the fault and restarted the car (albeit without waiting) and parking aid still isn't working. I will let the car go to sleep overnight and check again in the morning if it self-heals but has anyone got any ideas? Dreading booking it in at the dealer and waiting ages for a slot. I suppose it doesn't warrant calling LR Assist for this to speed things up, does it? Got a couple of trips coming up and also parking around here for a car this size is near impossible without parking sensors so would like this resolved soon.Current: Volvo XC90 T8 Inscription Pro PHEV with some optionals on top

workshop manual doesn't give much info, except that park button would flash if it detects any issues,
"The PARKING AID CONTROL MODULE (PACM) has a diagnostic connection via the high speed Chassis CAN bus to enable faults to be retrieved using the Land
Rover approved diagnostic equipment. Additionally an on-board diagnostic routine within the PACM constantly monitors the
system and alerts the driver to a system fault by emitting a 3 second continuous tone through the front audio speakers when
the ignition is switched on. The control switch LED will also flash 6 times when reverse gear is selected or the Parking aid
system switch is pressed."
