On Board Diagnostic (OBD) - 5 Spd. Automatic Transmission 01v Audi A6 C5

On Board Diagnostic (OBD), function

The automatic transmission is controlled electro-hydraulically.

The automatic transmission control module -J217- receives information from components that effect selection of gears and passes the information on to solenoid valves that control the solenoid valves in the valve body. The solenoid valves convey the fluid pressure generated by the ATF pump to the appropriate clutches/brakes to be engaged.

Transmission control module -J217- fault recognition

The term "On Board Diagnostic (OBD)" is specifically for the electronic/electric control.

The control module is equipped with a DTC memory so that in the event of an electronic/electrical component failure or on open circuit the fault can be determined quickly. Fault are recognized by electrical signals and stored in the DTC memory together with an indication of the type of fault and fault location.

The control module recognizes faults during vehicle operation and stores them in a DTC memory. This information will remain available even if the system voltage fails.

The control module distinguishes between faults present (permanent) and temporary faults (sporadic).

If a fault is no longer present after a certain period or a lengthy drive, it will be converted to a sporadic (SP) DTC.

A fault will also be converted to sporadic when the DTC memory is not erased after repairs.

Faults which are stored in the memory as sporadically occurring faults, will be displayed as "sporadic DTCs" when checked by the scan tool VAG 1551. In such cases "SP" appears on the right of the display. If the printer is switched on, the print-out will show "sporadic DTC" after the identification of the fault.

If the sporadic DTC does not occur again after 40 cold engine starts (and subsequent transmission warm-up), the fault in DTC memory will be automatically erased.

The possibilities offered by On Board Diagnosis can only be fully utilized with the vehicle diagnostic, testing and information system VAS5051 or the VAG1551 scan tool (mode 1, rapid data transfer).

For available functions of vehicle diagnostic, testing and information system VAS5051 or the VAG1551 scan tool, see LIST OF SELECTABLE FUNCTIONS .

Security functions of the Transmission Control Module (TCM)

When one or more components or sensors fail, the Transmission Control Module (TCM) -J217- activates the appropriate replacement functions or emergency programs. This ensures destruction-free operation of the automatic transmission with some effect on the function and quality of shifting.

When critical malfunctions occur with an active transmission control module -J217-, the currently selected gear will be held. "Mechanical emergency running mode with the control module active" is activated by the transmission control module -J217- as soon as the driving situation regarding transmission security and engine security permits it.

Scheme 588

1. The transmission shifts out of all forward gears into hydraulic 4th gear. The torque converter clutch is unlocked (not applied). All solenoid valves are de-energized.
2. Maximum shift pressure is applied to the power-transmitting elements.
3. Reverse gear can be engaged. The shift locksolenoid is active (in "P" and "N").
4. All of the segments of the transmission range selector lever display are lit up completely.
5. The MIL lights up after 2 Dcy); check DTC memory ( «CHECK DTC MEMORY»(/audi/a6/c5-1997-2001/remont/automatic-trans/#on-board-diagnostic-obd-5-spd-automatic-transmission-01v) ) and compare with «DIAGNOSTIC TROUBLE CODE (DTC) TABLE»(/audi/a6/c5-1997-2001/remont/automatic-trans/#on-board-diagnostic-obd-5-spd-automatic-transmission-01v) .

If the TCM -J217- malfunctions (e.g. if the power supply is faulty or the connector becomes disconnected), the transmission will immediately switch to "mechanical back-up mode with inactive control module" and continue to operate.

Mechanical backup with non-active control module

1. The transmission shifts out of all forward gears into hydraulic 4th gear. The torque converter clutch is unlocked (not applied). All solenoid valves are de-energized.
2. Maximum shift pressure is applied to the power-transmitting elements.
3. Reverse gear can be engaged. The shift lock solenoid is active (in "P" and "N").
4. All of the segments of the transmission range selector lever display are dark.
5. The MIL lights up when the Engine control module (ECM) has recognized a CAN-bus malfunction (missing data exchange between engine and transmission control modules) (after 2 Dcy); if necessary, check DTC memory of the control module.
6. Transmission control module -J217- does not function at all, i.e. it cannot be checked via On Board Diagnostic (OBD).

Scheme 589

Malfunction Indicator Lamp (MIL) function, checking

If emissions-influencing malfunctions are recognized by the TCM, the Malfunction Indicator Lamp (MIL) will be switched on.

Location of the MIL: integrated in speedometer in instrument cluster.

Scheme 590

Note. When the MIL is switched on, it will either blink or light continuously. In either case, the DTC memory for the TCM must be checked. See CHECK DTC MEMORY . MIL flashing: there is a malfunction that could damage the Three Way Catalytic Converter (TWC). In this case, drive only with reduced power. MIL continuously on: there is a malfunction that degrades emissions. Check DTC memory of the Engine Control Module (ECM) or the TCM. If there are driveability problems (e.g. a customer complaint) and the MIL is not on, the MIL functional test must be carried out, since malfunctions that do not immediately switch on the MIL can be stored.

MIL functional check

1. Switch ignition on. the MIL must come on. If the MIL does not come on when the ignition is switched on (with the engine not running): Check DTC memory. See «CHECK DTC MEMORY»(/audi/a6/c5-1997-2001/remont/automatic-trans/#on-board-diagnostic-obd-5-spd-automatic-transmission-01v) . If necessary, check wiring per wiring diagram or replace light bulb.
2. Start engine and let idle: the MIL must be switched off after several seconds.

If the MIL is not switched off after the engine is started: Check DTC memory. See CHECK DTC MEMORY .

Conditions for recognition of a driving cycle (Dcy)

A driving cycle (Dcy) is considered complete when the ignition is switched on one time, the engine is started, the engine start is recognized by the control module, and the ignition is switched off again.

Important notes

Note. In the following, all possible malfunctions are listed in ascending order of DTC. These malfunctions can be recognized by the transmission control module -J217-. They are then displayed on the VAS5051 tester or VAG1551 scan tool when checking DTC memory content. Starting on the next page is a list of all the DTCs with all MIL conditions. The DTC is only printed out in the "Rapid data transfer" operating mode when the printer of the VAG1551 ST is switched on. Example: DTC 16987 P0603 If malfunctions only occur sometimes or if DTC memory was not erased after malfunction repair, these malfunctions are displayed as "sporadic malfunctions" for a pre-determined time period. For malfunction recognition of transmission control module, see ON BOARD DIAGNOSTIC (OBD), FUNCTION . If components are indicated as being faulty during the check of DTC memory, also test the wiring to the components for short circuit and open circuit according to wiring diagram.

List of all DTCs with the MIL condition

Note. Dcy = Driving cycle. For conditions for recognition of a Dcy, see CONDITIONS FOR RECOGNITION OF A DRIVING CYCLE (DCY) . For meaning of the Malfunction indicator Lamp (MIL), see MALFUNCTION INDICATOR LAMP (MIL) FUNCTION, CHECKING . The "MIL" column in the DTC table indicates the condition of for which the Malfunction Indicator Lamp (MIL) would be switched on. If, for example, "2 Dcy" is indicated in the table, the MIL would light up after two driving cycles. If "Off" is indicated, the malfunction has no influence on the MIL.. If "On" is indicated, the MIL will light up immediately after the malfunction occurs. For "Hydraulic control" column: Which transmission is equipped with which hydraulic control can be found in: See CODE LETTERS, ENGINE/TRANSMISSION APPLICATIONS, RATIOS, EQUIPMENT .

Output Diagnostic Test Mode (DTM) (scan tool function 03)

Note. A differentiation is made between two types of transmissions: Transmission with hydraulic regulation -E17-, on which the transmission input speed sensor (inductive sensor) is secured to the underside of the valve body. Transmission with hydraulic regulation -E18/2-, on which the transmission input speed sensor (camshaft position sensor) is secured behind valve body at transmission housing.

For information on which transmission is installed, refer to

See CODE LETTERS, ENGINE/TRANSMISSION APPLICATIONS, RATIOS, EQUIPMENT .

Output Diagnostic Test Mode (DTM) for transmission with hydraulic regulation E17: See OUTPUT DIAGNOSTIC TEST MODE (DTM) (SCAN TOOL FUNCTION 03), TRANSMISSIONS WITH HYDRAULIC REGULATION -E17 .

Output Diagnostic Test Mode (DTM) (scan tool function 03), transmissions with hydraulic regulation -E17

Note. The Output Diagnostic Test Mode will be terminated if the engine is started. The Output Diagnostic Test Mode can only be performed when the selector lever is in position "P", the engine is not running and the vehicle is stationary. The function of the solenoid valves1 -N88-, 2- N89-, 3-N90- and the solenoids for the selector lever lock are checked acoustically during the Output Diagnostic Test Mode. Avoid noise in the surrounding area during the acoustic check, because the switching noise (clicking) of the actuators is very quiet. The solenoid valves 4 -N91-, 5 -N92-, 6 -N93- and 7-N94- are activated during the Output Diagnostic Test Mode. A direct functional check of these valves is not possible. But possible electrical faults which occur during the activation, will be recognized by the On Board Diagnostic (OBD) and stored in the DTC memory.

Note. When performing the Output Diagnostic Test Mode the individual actuators will be activated until the --> button is pressed. Only one complete Output Diagnostic Test Mode is possible after switching the ignition on. To repeat the Output Diagnostic Test Mode the ignition must be switched off and on again.

Bus

The term bus refers to a system that transports and distributes data.

CAN

The Controller Area Network is a bus system that uses two wires. These are called bus wires. Data is transferred to the connected control modules serially (one after the other) across the bus wires.

These control modules communicate with each other via the CAN-bus.

Overview of power train data-BUS

Note. The following list refers to items in (Scheme 855).

1. Transmission Control Module -J217
2. Driver for BUS
3. Motronic Engine Control Module (ECM) -J220

5. Refer to the DTC table in the relevant repair manual for help in fixing the malfunction. You have fixed all malfunctions
6. Check bus wires if communication to the control modules is still faulty.

While checking the bus wires, make a distinction between the following two situations

1. Two control modules communicate via a "two-line bus system"
2. Three or more control modules communicate via a "two-line bus system"

Two control modules communicate via a "two-line bus system"

1. Switch ignition off.
2. Disconnect both control modules.
3. Check the bus wires for an open circuit.

Scheme 852

1. Check whether there is a short circuit between the bus wires.

Scheme 853

1. Check the bus wires for a short circuit to B+ or Ground (GND).

If no malfunctions could be found in the bus wires

1. As a test, replace one of the control modules. Select a control module that will take the least amount of time, and cost the least amount of money to replace.
2. If communication between the control modules across the bus is still interrupted, replace the second control module.

Scheme 854

Three or more control modules are communicating across a "two-line bus system"

1. Analyze the DTCs stored in the memories of the control modules.
