BC Test Functions (IKE E38, E39, E53): Notes

The BC test functions are used to check inputs, outputs and functions of the IKE. There are 21 possible test steps. With the exception of Test # 1,, # 2, and # 19, all other tests are locked but can be released through test # 19.

The test functions are displayed in the instrument cluster. Test number 01 is called up by pressing the CC button for 10 sec. The same activation can be initiated by pressing and holding the CC button while switching on the ignition.

Using the trip meter reset button enter by pressing the sum of the last 5 digits of the chassis number, example: VIN GB11111, - 1 + 1 + 1 + 1 + 1 = 5, press the reset button 5 times.
