The above errors indicate problems in mechatronics soldering.


1.errors 1x6, 1x7, 1x8:

The resistance meter should show infinity when we measure the resistance between the case and any pin of the 8hp plug or

should be higher than 1M Ω (R > 1MΩ)


resistance below 1M Ω (R > 1MΩ) may cause errors  1x6, 1x7, 1x8

where x is the selenoid number.


the reason is most often impurities inside the CASE



2. errors 00x :


Problems with a damaged harness, 8hp gearbox pins or TCU plug pins where the problem is with the connection most often cause errors 00x

where x is the selenoid number


You need to check the connections between the 8hp plug and the TCU. Check that the pins connect and that they are plugged into the correct pins of the TCU.


If that didn't solve the problem then you probably have bad PCB/wires soldering in mechatronic.

Selenoid 1: 5,5Ω

Selenoid 2: 5,5Ω
