Engine Controls - on Board Diagnostic (OBD) -1.8l 5v Turbo, Amb Audi A4 B7

Features

1. Data transfer between control module and vehicle diagnostic, testing and information system VAS 5051 is carried out in "self-diagnosis" mode.
2. Diagnostic Trouble Code (DTC) memory: Non-volatile and volatile memories.
3. Display of stored DTCs occurs after initiation of display mode. Go to «DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING»(/audi/a4/b7-2004-2009/remont/testing-diagnostics/#engine-controls-on-board-diagnostic-obd-18l-5v-turbo-amb) .
4. DTC memory must be erased after malfunction is repaired. Go to «DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, ERASING»(/audi/a4/b7-2004-2009/remont/testing-diagnostics/#engine-controls-on-board-diagnostic-obd-18l-5v-turbo-amb__diagnostic-trouble-code-dtc-memory-erasing) .

Malfunction Indicator Lamp (MIL) -K83- in instrument cluster

If the engine control module (ECM) detects malfunctions which result in deterioration of exhaust emissions, these malfunctions will be indicated by illumination of exhaust gas warning lamp.

After switching on the ignition the ECM switches on the Malfunction Indicator Lamp (MIL) -K83-. Shortly after starting the engine, the MIL goes out if the ECM does not detect a malfunction through a deterioration of the exhaust emissions, and if the ECM activation of the lamp is ok.

If DTCs which cause the exhaust emission to deteriorate are detected when operating the engine, the ECM switches on the MIL. (These DTCs are listed in the DTC table). At the same time, an entry is made in the ECM DTC memory.

When switched on, the MIL may flash or illuminate constantly. In any case the DTC memory must be checked. Go to DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING .

Continuous illumination

A malfunction is present which causes deterioration of the exhaust emission. Check DTC memory for ECM or automatic transmission (if available).

If there is a drive problem or a customer concern and the MIL is not illuminated the DTC memory must be checked. DTCs which do not switch on the MIL immediately, but only after recognizing the malfunction after restarting the engine, can also be stored.

Flashing

A malfunction is present which under these driving conditions will cause damage to the Three Way Catalytic Converter (TWC) (e.g. misfiring). In this case driving may only continue at reduced power.

Functional check on MIL

1. Switch ignition on. The Malfunction Indicator Lamp (MIL) -K83- for self-diagnosis must illuminate.
2. Start engine. Shortly after starting the engine the MIL goes out if no exhaust emission related DTC is stored in the DTC memory.

Note. The switch-on signal for the MIL is transferred via CAN-bus to the instrument cluster by the ECM. Check the data exchange between ECM and other CAN-bus control modules. Go to DATA EXCHANGE, MOTRONIC / ABS (CAN-BUS), CHECKING .

Diagnostic Trouble Code (DTC) Table

Note. If malfunctions occur in the monitored sensors and components, these are stored in the Diagnostic Trouble Code (DTC) memory together with an indication of type of malfunction. Malfunctions related to EPC are additionally indicated by the warning lamp for the electronic throttle control ("EPC warning lamp") which is situated in the instrument cluster. Notes on EPC system. Go to ELECTRONIC POWER CONTROL (EPC) SYSTEM, CHECKING . Malfunctions that worsen emissions are indicated by an exhaust warning lamp (MIL) that is also located in the instrument cluster. There are malfunctions that cause the exhaust warning lamp to light up immediately after recognition. Malfunctions can also occur that cause the exhaust MIL to light up, but only if malfunction is recognized again after repeated engine starts. Notes for exhaust warning lamp (MIL). Go to MALFUNCTION INDICATOR LAMP (MIL) -K83- IN INSTRUMENT CLUSTER . Malfunctions which cause the exhaust emission to deteriorate are displayed with an exhaust warning lamp in the instrument cluster. Notes on exhaust warning lamp. Go to MALFUNCTION INDICATOR LAMP (MIL) -K83- IN INSTRUMENT CLUSTER . The malfunction table is sorted according to the 5-digit DTC on the left. Sporadic malfunctions (malfunction occurring from time to time) are indicated as "sporadic" on the display. The word "sporadic" signifies individually occurring, random malfunctions. Do not immediately replace components indicated as faulty by the VAS 5051 but: first check the wiring and connectors of these components against the wiring diagram. Also check the ground (GND) connections against wiring diagram. This is particularly relevant for DTCs recorded as "sporadic." If the connector is pulled off the engine control module or if the battery is disconnected, all the stored values in the control module will be erased. However, the contents of the Diagnostic Trouble Code (DTC) memory are retained. If the engine is then started, it may run rough for a short period. In this case, the engine should be run at idle for a few minutes until the adaptation process is concluded. After erasing the Diagnostic Trouble Code (DTC) memory. Go to DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING . The readiness code must be regenerated. Go to READINESS CODE, GENERATING .

Output Diagnostic Test Mode (DTM)

Note. The Output Diagnostic Test Mode (DTM) can only be performed with the engine stopped and the ignition switched on. During actuator diagnosis, the individual actuators (with the exception of the injectors) are operated in turn for about one minute unless the next actuator is selected by pressing the > button. The control elements can be checked acoustically or by way of touch. The Output Diagnostic Test Mode (DTM) is terminated, if after 1 minute actuation time the next control element is not switched to, or the engine is started or an engine speed pulse is detected. Before restarting the Output Diagnostic Test Mode (DTM) the engine must be started and the ignition switched off and on again.

Readiness code

The readiness code appears as an 8-digit display on measured value block 086, display zone 1. Each of the 8 digits is allocated to a particular emission-related system.

The function of each of these systems is checked by the self-diagnosis and the relevant position for the system in the 8-digit display is changed from "1" to "0" in a test sequence which must be fully completed.

The readiness code produced after successful completion of the test sequence is then "0 0 0 0 0 0 0 0" (measured value block 086, display zone 1).

If an individual test has been completed, but is "not OK", a DTC is entered in the Diagnostic Trouble Code (DTC) memory. Checking Diagnostic Trouble Code (DTC) memory. Go to DIAGNOSTIC TROUBLE CODE (DTC) MEMORY, CHECKING AND ERASING .

The readiness code is reset to "0 1 1 0 1 1 0 1" if

1. Diagnostic Trouble Code (DTC) memory has been erased
2. Voltage supply to the ECM has been interrupted (e.g. the connector disconnected, battery disconnected).
3. A new Engine Control Module has been installed

Generate readiness code. Go to READINESS CODE, GENERATING .

Note. When driving with varying loads the exhaust relevant tests are initiated by the control module and the readiness code produces itself. In this case the concluding control possibility is omitted, i.e. it is not obvious whether the vehicle was handed over to the customer without any DTCs.

Note on display zone 1

Display zone 1 is the most important. This display indicates which system has been checked by the self-diagnosis since the last time the Diagnostic Trouble Code (DTC) memory was erased or since installation of a new control module. After erasing the Diagnostic Trouble Code (DTC) memory, all testable values are set to "1" and then to "0" after successful completion of the test.
