Instruction about Reading and Writing on Volvo GPT vehicles with KTAG ECU Programmer.

 

This is a Ktag help file used for Volvo Bosch EDC17 on GPT vehicles.

 

To use this protocol of communication you have to remove and open the ECU. It is a risky operation, to be done with great care and caution to avoid damaging the ECU beyond repair.

 

After opening the ECU and before proceeding with reading and/or programming, you are strongly advised to reconnect the unit to the vehicle and start the engine, to make sure it still works.

 

To use this protocol you also need to connect to the ECU connector through a cable, and solder one or more wires to the programming pads.
