Autotuner No Connect with VW DCM6.2V via OBD Solution

Problem:

Trying to read a VW Transporter 2.0 Delphi DCM6.2V ECU with Autotuner via OBD.  Autotuner reads the ECU ID but cannot connect to ECU.

Gave an initialization error 02.

What's the solution?

Autotuner No Connect with VW DCM6.2V via OBD

Solution:

1). When initializing ecu, try ignition off and after 3 sec ignition on. This can also happen on VW Crafter.

2). Check if there is an aftermarket alarm installed. Block it and try again.

 

 

 

User feedback:

The issue is resolved.

An aftermarket alarm was installed, blocking the engine via CAN.

ODIs online and firmware update again.
