VOLVO Bosch EDC16+ C31 Kline

In some recent cars, K-line is not wired inside the OBD II socket of the car; in this case using OBD cable you will get communication errors (0x3000 wake-up error). It is therefore necessary to make the connection directly on the ECU connector by using the Kabel uniwersalnys 144300K201.

Follow these steps to make the connection:

1. Detach the little connector of the ECU and pull off the plastic cover as pokazanego na zdjęciu.
   
   



2. Locate PIN 43 of the connector, which allows communication with the ECU. To create the connection, link the K-line (yellow wire) to the Kabel uniwersalny to PIN 43 as pokazanego na zdjęciu below. Then connect the red wire to the positive pole of the battery (+12V) and the black one to ground (GND) using clamps.
