Preparation

The following tests and activations are possible via the Hand-Held Tester.

Preparation for Test
1. Fuses ok,
2. Battery voltage > 11,
3. Connect the Hand-Held Tester (HHT) to X11/4
4. Voltage Supply to the control modules and CAN data lines. Component Tests and General Diagnostics
5. All CAN data lines properly connected.

NOTE: The actual values and activations of any system may be stored in numerous other control modules, therefore readout all actual values and activations from the control modules which are relevant to this system. When reading out the actual values, all stored in that control module will be shown.

CAUTION: Erasing the Convenience Feature (CF) DTC memory, will also erase the DTC memory for the Combination Control Module (N10-1) and Minor, steering column adjustment, heated mirrors (MSC).
