Checking wiring connection between automatic gearbox control unit -J217 and gearbox — AUDI

Requirements for test:

Gearbox control unit disconnected
Ignition off
Test box V.A.G 1598 A connected to the already unplugged multiple connector on gearbox wiring harness via adapter lead V.A.G 1598/5

Set down the test box outside of vehicle.

Checking wiring connection of multi-function switch -F125

Release spring catch on connector -1- for multi-function switch -F125.

Test wiring connections for open circuits and shorts to positive or earth.

Testing wiring harness in gearbox

Note:

Perform this test if the solenoid valves do not click during final control diagnosis or the electrical test of the solenoid valves via test box V.A.G 1598 A detects a fault, but the wiring connections between the gearbox control unit and the 8-pin connector are okay.

Connect multimeter (resistance measurement range) as follows:

Component · Connector contacts · Specification ω
Solenoid valve 1 -N88 · M + H · 30 ... 40
Solenoid valve 2 -N89 · M + K · 30 ... 40
Solenoid valve 3 -N90 · M + L · 30 ... 40
Solenoid valve 4 -N91 · M + B · 5 ... 8
Gear oil temperature sender -G93 / at approx. 20 °C · E + F · 500 ... 3000 / / 940

If a specification is not met:

Detach wiring harness from relevant solenoid valve and test according to current flow diagram. If necessary, replace wiring harness.
Measure resistance at solenoid valve again and replace valve or valve body if necessary.
