Peugeot Planet PP2000 question.

Hello everybody,

My Peugeot 206 CC 2.0 won’t start anymore in the morning after a stormy night. I never had any start problems before faults or problems before. I called road service for it, and they came to check. After 1 hour checking my car by this road service and now stucked in economy mode he told me.. its almost sure it’s the Motor ECU and he left. Today I started to try to diagnose the car myself and hooked up the PP2000. After reading out the car it shows for sure no communication with the Engine ECU (see picture 1). But I want to start at the beginning to excluding things out, so I start at the (BSI) and noticed that there is also NO key synchronized as shown in the second picture (see picture 2).

Also my car doesn’t make beeping sounds anymore while the key is in the contact when opening the door.

My questions on this:

1 is it normal that PP2000 shows the list of 5 keys with No synchronized?

2 Is it normal that my car doesn’t make pings anymore when the key is in its contact and I open the door because its in ecomode?

I want to know this because before I continue to the Engine ECU what shows also as locked.

I would focus on why the ECU is not communicating. Could be that it is not powering up??? I would certainly suspect a wiring loom issue over the ECU failing

Sounds like it might be your issue. Worth checking continuity on the loom feeding that pin. Maybe you have a break? Or maybe the BSI is not powering it?
Measure voltage from positive to negative on the battery and then to various ground points. Do the measurements differ by 26 Mv? If not then it’s your meter not being very accurate at low end of the range

DC 0.1mV~600V(0.8%5) what it says on the box. Not sure in real, but going to check.
I have a couple of multimeters and I don’t find they are brilliantly accurate :( so it was just a thought
