The actual values and activations of the infrared remote central locking system with DAS 3, are located in various control modules. With the HHT it is possible to gain access to the actual and activation is as follows: Functions - Locking systems - Central locking or Drive authorization - Actual values or activations. Abreviations: DBE Roof control panel control module (N70) EZS Electronic ignition switch (N73) SAM Signal pick-up and activation module (N10/1) The above noted abreviations are in the second column of the following actual values table in bold type to advise of hints (regarding in which of the control modules the actual values or activations are stored).

Preparation for Test: 1. Fuses ok, 2. Battery voltage 11 - 14 V, 3. Voltage to control modules and CAN data lines ok, 4. Connect the Hand-Held Tester (HHT) to X11/4, according to diagram, see section 0. The following actual values can be read out using the HHT: - Status of electronic ignition key: Initionalized/Anti-towing safety released/personnalizer /activation - Status of electrical steering lock: Initionalized/Anti-towing safety released/personnalizer /activation - Status of transmitter key: Authorized/not authorized Used/ not used - Electronic ignition key test cycle counter - Electrical steering locking test cycle counter
