Hi to everyone, So I got back to research. I made a shunt from a resistance of 1.65 MOhm on a hybrid board - the contactors started working, car goes into READY mode, everything works, but !!! Diagnostics shows that the charge level of the capacitor is now 361 V, with a battery charge of 355 V -...

thanks Kiev for the advice and help. I mainly use Autel Ultra Lite in Power probe 4. I have original programs for any brands, but Citroen is a rare guest, so Mut is absent. I put the work on pause, but I will be back soon and I will definitely write what the reason is. I also want to check hiter...

I checked the signal of the control unit EV-ECU to the main contactors: in connector C-111 I checked pin 105,106,107. 105 and 106 - ok - at start, the battery voltage is applied and then decreases to 0.8 V 107 - there is no signal to the contactor + it's allways 0,8 v any idea why the control...

battery voltage 355V in the live data, the capacitor voltage rises only to 40V !!!

I continued my research: checked the transistors under the bottom lid - it's ok. I checked Can - the signal is good. then I noticed a pattern: when I connect everything - there are three errors and a yellow service lamp. P1B31 - brake fluid pressure sensor fault U1113 - DTC to be ignored P1A15...

removed the converter, opened the bottom cover. no visible damage. fuses are all ok. direct wire to 12v battery is ok. MCU fuse that located under smal lid on invertor - ok any idea?

when the key is turned, there is no click of the relay, only the sound system fades out

thanks for the response. the car came to me with a completely empty 12v battery. I connected another one along with charging to do diagnostics at the first error reading, the ECM_EV block issued the following codes: P1B31 - brake fluid pressure sensor fault U1113 - DTC to be ignored P1A15 -...

Hello everyone from sunny Finland :)) I'm asking for help because I'm stuck. Citroen c-zero does not go into ready mode, the 12 V battery charging lamp and the low brake fluid level lamp are on. no 12v battery charger. the OBC unit does not communicate with the diagnostic equipment. checked the...
