Flex Failed to Read Mitsubishi Fuso EDC17CP52 ECU Solution

Problem:

Tried to read a Mitsubishi Fuso Canter 3.0DDI 173 ps EDC17CP52 ECU with MMS Flex on bench mode but cannot read. What’s the problem?

Solution:

Same problem can also happen to other tools. You cannot even read this with Dimsport New Trasdata. You must open ECU and do it boot only.

2 solutions:

1). Open ECU and read in boot mode.

2). If you need to do it on bench mode, add a capacitor (10uf-50uf) on each GPT.

Must add capacitor to gpt pin this pinout also works for Edc17cp15.
