PCMTuner Module 71 Bench Mode Not Working Solution
Here are the tips if failed to read ecu edc17cp45, edc17c06 etc on bench mode with pcmtuner module 71.
PCMTuner comes with spare transistors for GPT circuits, lots of people damage these by connecting wrongly to ECU so these are replacements if it happens.
If you use OBD for power supply, please do not plug in a separate 12V, otherwise, it will cause the device transistor or step-down chip to burn.
MUST USE PCMtuner power supply!
If you use your own lab power and voltage regulator. You don’t know how device power works. Just adjust the voltage to 13.5 or whatever you think will cause the whole triode to burn out.
The solution here helps many users with similar problems. edc17c60, edc17cp45, edc17cp06 all tested working on bench mode.
Resoldered two transistors K1P, and work bench mode. One soldered K1P other analog p1P, I had only one K1P.
replace first this transistor, K1P, analog 1P,p1P
k1p mmbt2222a – 0.6A 40/75V and p1p pmbt2222a – 0.8A 40/75V
