Hello All,
I went to the LR4 2 weeks ago and got the "Smart Key not Found" when trying to start and remote locks would not work.
1- Replaced the Fob Battery
2- Car Battery charged - (3 months old)
3- Codes found using GAP Tool: (so I can't do a deep scan or communicate with the KVM with the tool )
B1B01-87 (2E) Key transponder - Bus signal/message failure - missing a message
U201F-31 (2A) External receiver - Frequency modulation/pulse width modulation failure - no signal
So, looked at many posts here and elsewhere - Suggesting the KVM has gone bad - they are somewhat common
4- I got a used working KMV - and had it cloned to my existing KMV - no issues with that process.
Same Codes.
Clear them.. both KMVs give the same codes.
In between this process,..... water dripped from the A-Pillar - Passenger side (LHD) - CRAP
It was a clogged sunroof drain - no issues with the tube... actually took all the panelling off to check.
5- Checked Wiring to KMV
Good Ground - Black
12V+ to Power - Red
2.5V to Power - Brown (when running)
2.5V to Yellow/Blue - Communication wire (when running)
Next, I am going to replace the Radio Frequency receiver above the driver's seat. Based on the code details and suggested course of action Its 100 CND... so not a expensive test... just waiting for the part - 2 days.
Do you have any other suggestions before I take it to the Indy dealer?
Thanks for the help!
