Flex Korhex Unlock DAF Delphi ETC3 UDS ECU

MMS Flex Korhex DAF Delphi ETC3 UDS locked ECU unlocking review:

With the new Flex + Korhex solution, ETC3 UDS units can now be unlocked and programmed directly in our workshop, eliminating the need to ship the control unit elsewhere.

Supported DAF models with Delphi ETC3 UDS:

• DAF CF (IV)
• DAF XF 106 (II) 2017–2024
• PACCAR MX-11 10.8L / MX-13 12.9L

 

"It’s a hard job to open the ECU. Took more than 1 hour to open the ECU.

Tips to open the case: Use a hydraulic press with wooden blocks to secure the connectors and prevent them from moving. Then, use a large pry bar to remove them.

You connect your 12v starter (or the one provided by flex on the tool) but the ECU you connect directly in 24V.
The only pins you use fromFLEXare CAN L / H and PW 1/2.
You need 2 power supply one 12v for flex box only!
And one for powering ecu ( so put +24v on pin 1 and 60 and ground on pin 57 ).
Start boot glitch unlocking.

After unlocking, no need to useKorHex.

Read and write with Flex, all done.”
