Diagnosable Tiptronic control unit
A self-diagnosis feature with fault memory is built into the Tiptronic control unit to allow certain faults within the electronic control system of the Tiptronic to be detected and to be stored. To prevent detected and stored faults from being erased when the ingition is switched off, a permanent positive voltage is present at the control unit. Detected faults remain stored in the fault memory for at least 50 starts of the engine. Caution If the connector is pulled off the Tiptronic control...
Test point 0 K and L wire
The diagnostic connection between the ECU control unit and the tester is made across the K and L wires. If it is not possible to run a diagnosis on all systems, the following checks should be made 1 Continuity check refer to wiring diagram - L wire Pin 7 diagnosis socket to Pin 13 ECU connector - K wire Pin 8 diagnosis socket to Pin 51 ECU connector 2 Short to ground check refer to wiring diagram - L wire The voltage at pin 7 diagnosis socket should be gt 8 V when the ignition is switched on. -...
Faults that cannot be detected by selfdiagnosis
The ECU cannot detect and store all potential faults. If a fault is found and if no fault has been stored, the tester may be used to run a system check to indicate any faults that may be present. Some of these faults are stated below. No diagnosis possible, Test point 0 No diagnosis is possible if the diagnostic leads are faulty. If terminal 15 is inoperative, the system enters the mechanical-hydraulic emergency mode. The fault lamp does not come on. If terminal 30 is inoperative, all faults...
