BMW Scanner 1.4.0 cant connect to LCM

Hi,

I bought a used bmw 2002 330i recently and I am using a bmw scanner 1.4.0 on windows 7 x64 with the latest drivers and it connects to the car ok, but i cannot connect with the lcm at all. Also only 2 or 3 modules are found on page 2 and 3, i dont know if this is normal. I tried with and without the 7+8 pin connected together. I get alot more info when they are shorted. I make sure the key is turned to "on" position 2. I purchased the scanner from newegg. I was not showing the DME and EWS so i soldered pins 7+8 together and now it shows those but still no LCM. I tried this on windows xp as well same result. when i first startup the scanner software it says turn key to on and press continue, i do that and receive the lcm:fa error. Then when scanning it cannot connect to LCM either.The car also shows a 1000 mile discrepancy between the dme and ike but the vin matches so who knows whats going on with that. The IKE is showing the errors below. Is it a good possbility that since i cannot connect to the LCM that the IKE cannot connect either and thats why it thinks there is a data-filing difference? The car seems to run fine and all the lighting is functioning properly

IKE -> BE/C8 - Data-filing difference to central light module (LCM)
BF/C8 - Internal fault, EEPROM checksum, coding incorrect/incomplete

Don't get caught up on the mileage difference. Not all of the modules store the least significant digits of the odometer reading. Perhaps your LCM has a fault?

I am not sure if it has a fault. Thats what i am trying to verify. Everything is functioning as it should except i cant connect to it. I am not sure if i should inspect the circuit board, or if its another problem im missing.

Do you think pulling the battery connection and doing a 2hr reset could fix it?
