Facing car non-starting issues with a 2018 Citroen Berlingo equipped with ECU EDC17C60? You’re not alone. Here, we delve into a common challenge encountered when using ECUHELP KT200 on bench mode, offering solutions to get your vehicle back on the road in no time.

The Challenge:
A frequent dilemma faced by many is the car failing to start after a couple of successful attempts following the initial reading and modification with the KT200. Error codes p151A and P3028 usually accompany this problem, indicating potential errors in the tprot and checksum adjustments performed during the modification process.

Insight into the Issue:
The root of the problem seems to be in the manual manipulation of Tprot and checksum using winols, often resulting in badly modified files and subsequent non-starting issues. It seems that the adjustments made during the ‘adblue off’ procedure, and subsequent file rewriting without KT200’s automatic checksum correction, are contributing to the persistent problem.

The Solution:
To bypass this hiccup, entrust the KT200 with the tprot and checksum adjustments, avoiding manual interventions that might lead to errors. It’s essential to let the tool auto-patch and auto-correct the checksum unless the write fails, which occurs in a minor percentage of cases (between 70-90%).

If faced with write fails, modify the original file meticulously, manually turning off tprot and adjusting the checksum accordingly. Once modified, use KT200 to correct the checksum automatically before proceeding to write the eeprom original. Using Lsuite for manual tprot and checksum adjustments is also proven to work seamlessly.

By following these revised steps, you can evade the persistent non-starting issues, paving the way for a smoother, more reliable vehicle operation.
