Vehicle Information Storage
The BC1 stores the total mileage and service interval data (SIA) in memory as back up for the IKE.
The Vehicle Identification Number (VIN) is entered during coding of the BC1 and can only be over-written if the total mileage is less than 100 km. The VIN stored in the IKE and BC1 are checked each time the ignition is switched on.
The mileage and SIA data is also updated in the BC1 every 100 km (62 miles) of continuous driving.
The BC1 will not accept mileage from the IKE if the value stored is over 1000 km less than that stored in the IKE. If this occurs the BC1 must be replaced.
If both the BC1 and the IKE have to be replaced, replace one module, and only after coding it, replace the other module.
NOTE:
Never replace both the IKE and the BC1 at the same time. If this were to occur, the mileage stored and displayed will reset to 0 miles. If the mileage of the vehicle is not known, a vehicle disclosure statement sticker has to be placed on the B-Pillar with the mileage set to TMU (Total Mileage Unknown).
