Question Occupancy Sensor Programming???

Recently bought a 2006 LR3 for my daughter. Have gotten everything else on it in top shape (many thanks to everyone on these forums) but have one issue I am not sure of.

The airbag light is on so I took it to a dealer to diagnose it. It gace them codes B1A00 and B00A0 indicating Occupancy Sensor Control Module failure. Is it normal with this problem to replace the entire seat cushion rather than just the module that is bad? Also, they state "Install and Programming - 4 hours" on the quote. Does this module have to be programmed once it is replaced? And if so, will an iCarSoft LR V2.0 do the programming?

Thanks in advance,
Ken Carr

Default sensor

They’re $50 on eBay. I can walk you through the install. There may be a calibration as it uses air pressure on the switch. Module may work with out programming.
I have one I can send you. If it doesn’t work (meaning needs programming), send it back. Do you have a Gap tool to reset the light?
What part of the country are you in?

Default Wiring?

Wonder if you have a bad wire/connection. Could be worth checking continuity from the footwell to the sensor.

I bought one on ebay already (was only 25 bucks so thought it was worth a shot) and have it heading this way. I should have it in a couple days. I also have an icarsoft LR v2.0 on the way from Atlantic British that should reset the light if it works the way the icarsoft site said it will (spent the money cause it will work with my Jag XE also). Just didn't know if the LR V2.0 would actually program it if it needed it. I have the old one out already, so just waiting for the new one to arrive. I am in WV by the way, so a little far from LA .

Thanks
KC

Here are 2 extracts from the workshop manual regarding the 'Occupant Classification Sensor' and 'Restraints Control Module'.

though I assume it's the seat sensor that is to be replaced, part Nē LR017308. It appears that the part may be available separately, but needs T4 or equal to program, but I'm only guessing as it doesn't come up often. I've certainly not seen it before, hopefully someone else can help more.

Good idea, although I despise electrical troubleshooting....

Hmmm, good stuff. T4 or equal... would the iCarSoft LR V2.0 be a "T4 equal"?

The staple around here is the Gap Diagnostics IID tool. I have never heard of the one your using. From what I gathered by looking at the ICarSoft page it seems like most of the tools simply scan for codes. The IID tool is great because it also lets you do all the programing and configuration you need. Honestly, every new owner of an LR3 should buy an IID. It will save you money. Ive had mine for less than a year and has saved my butt and wallet numerous times.
