Connecting adapterV.A.G 1598/20 (test box) to automatic gearbox control unit J217 — AUDI

🧭 Before you start

Fits: Audi A8 D2 (4D)

• Special tools named: V.A.G 1594

📋 Procedure

1. Unscrew bolts (1) a few turns.
2. Unclip plenum chamber cover (2) (right-side) (arrows) and detach cover.
3. Remove cross-head bolts (arrows) (for access to bolt at rear left lever out cover (1) in cowl panel trim).
4. Detach cover for electronics box in plenum chamber.
5. Unclip control unit from electronics box (arrows)

6. Unplug multi-pin connector from gearbox control unit (3).
7. To unplug multi-pin connector release connector by pressing catch in (direction of arrow). In order to do this, switch off the ignition first and wait for at least 30 seconds.
8. Connect adapter V.A.G 1598/20 (test box) to automatic gearbox control unit J217.
9. ⚠ To avoid damaging the electronic components, always select the appropriate measuring range on the tester before connecting the test leads and observe the test requirements. — Carry out all the test steps listed in the column headed "“Fault rectification if readout does not match specification”".
10. Only perform the test steps recommended in the fault table (selective fault-finding).
11. After performing electrical check, fit 88-pin connector onto pins of automatic gearbox control unit J217 and then lock in place. [Note: Use hand-held multimeter V.A.G 1526 B with test leads from V.A.G 1594 C or vehicle diagnostic, testing and information system VAS 5051 with test leads VAS 5051/7 for checking. The socket designations of the adapter V.A.G 1598/20 (test box) are identical to the contact designations of the automatic gearbox control unit J217 in the current flow diagram. Adhere to correct test procedure to avoid damage to the system. Apart from the connectors listed in the test table, no other bridges may be connected. The given specifications are valid for an ambient temperature from 10 … 40 °C.If the measured values differ from the specifications, determine fault using current flow diagram. If the measured values differ only slightly from the specifications, clean sockets and connectors of the testers and test leads (use contact sprayG 000 700 04) and repeat test. Before renewing components it is necessary to check the wiring and connectors first. Particularly if specifications are below 10 Ω, repeat resistance measurement at component.]
