Audi Workshop Service and Repair Manuals

Carry out the following test if:

• ◆ the final control diagnosis or
• ◆ the electrical test indicates faults in the gearbox, gearbox control unit -J217 or in the wiring in between.

Test requirements

• ◆ Ignition switched off
• ◆ Connect test box V.A.G 1598/18 only to 68-pin connector on gearbox wiring harness.
• ◆ Take measurements with test box V.A.G 1598/18 outside the vehicle.

List of connectors which have to be disconnected for testing

• 10-pin connector to valve body
  =>Testing, Page 01-160
• 3-pin connector to road speed sender -G68=>Testing, Page 01-165
• 8-pin connector on multi-function switch -F125=>Testing, Page 01-162
• 2-pin connector on gearbox speed sender -G38=>Testing, Page 01-167

Testing wiring to 10-pin connector on valve body

• ‒ → Press catches -arrows A- on both sides and pull off connector upwards=>Location see Item 01-159.

• ‒ → Use hand-held multimeter V.A.G 1526A or V.A.G 1715 to test continuity of wiring between contacts on 10-pin connector and sockets on test box V.A.G 1598/18.

See the following table for resistance specifications.

Notes:

• ◆ If the readings obtained in these wiring tests match the specifications, check the wiring harness in the gearbox. To do this, remove conductor strip.

=> Automatic gearbox 01M; Repair group 38; Removing and installing valve body; Removing and installing conductor strip with 10-pin connector

• ◆ Only renew the valve body if no faults are found in the wiring harness in the gearbox.

Testing wiring to multi-function switch (8-pin connector)

• ‒ → Disconnect 8-pin connector from multi-function switch
  =>Location see Item 01-159.

• ‒ → Use hand-held multimeter V.A.G 1526A or V.A.G 1715 to test continuity or voltage of wiring between contacts on 8-pin connector and sockets on test box V.A.G 1598/18.

See the following two tables for resistance and voltage specifications.

Notes:

• ◆ If the results of test step 4 in test table on Page 01-19.
• ◆ If the readings displayed when reading out the relevant measured value block do not match the specifications, but no faults are found in the electrical test, renew multi-function switch -F125=>Fig.01-19.

Testing wiring to road speed sender -G68 (3-pin connector)

• ‒ → Press the catches -arrows B- on both sides and pull off connector upwards=>Location see Item 01-159.

• ‒ → Use hand-held multimeter V.A.G 1526A or V.A.G 1715 to test continuity of wiring between contacts on 3-pin connector and sockets on test box V.A.G 1598/18.

See the following table for resistance specifications.

Notes:

• ◆ If the readings obtained in this wiring test match the specifications, renew road speed sender -G68
  =>Fig. 01-21

Testing wiring to gearbox speed sender -G38 (2-pin connector)

• ‒ → Press the catches -arrows- on both sides and pull off connector on sender upwards=>Location see Item 01-159.

• ‒ → Use hand-held multimeter V.A.G 1526A or V.A.G 1715 to test continuity of wiring between contacts on 2-pin connector and sockets on test box V.A.G 1598/18.

See the following table for resistance specifications.

Notes:

• ◆ If the readings obtained in this wiring test match the specifications, renew gearbox speed sender -G68
