Closing the doors with the remote control and the cruise control not working.

Post by Thetrill »

Hello,
I recently owned a Citroen C4 Picasso 1.6BlueHDI from 2016. facelift version.

I have a problem with the door closing with the remote control not working.

I replaced the battery in the remote control.
The remote control has been checked with a tester - it sends the signal correctly.

I disconnected the battery for several minutes to restart the computer in the car.

The diagnostic computer shows two keys added to the vehicle. Unfortunately, I don't have the equipment to reprogram the key.

I checked all the fuses.

Does anyone of you know any procedure for adapting/synchronizing the key with the car?

I will add that the car starts normally after inserting the key into the slot, and the central locking system closes and opens all doors correctly using the key blade.

I will also add that today I noticed that the cruise control in this car does not work. I don't know if it's somehow related.

Diagnostic trouble codes:
B1328 Rear screen and/or mirrors control fault
B132A Air conditioning circuit low pressure
B1505 Microphone input fault
B1000 Calibration downloading foult

Thank you for all your help.

Pop the VIN up so we can relate these codes to the vehicle specially.

B1328: The last 2 digits of the fault code are missing, so could be either B132811 or 15.
Fault Code: B1328 11
Description of Fault: Rear screen and/or mirrors de-icing control fault: Short circuit to earth. Detection of a short circuit to earth. (Activation impossible or random deactivation of the rear screen and/or door mirrors de-icing control).
Conditions of activation of the diagnostics
The following conditions have to be met:
- Engine running
- BSI output in non-operating mode (Rear screen and/or mirrors de-icing control)
Conditions for Fault to clear:
  • Absence of short circuit to earth
Downgrade Modes whilst Fault is active:
  • Deactivation of the BSI output (Rear screen and/or mirrors de-icing control)
Symptoms:
  • Malfunction of the de-icing of the rear screen and/or mirrors
  • Consumption of power is excessive
Suspect Areas:
  • Built-in systems interface
  • Passenger compartment fuse box (BFH3)
  • Relay "R1" of the passenger compartment fuse box (BFH3)
  • Electrical harness
  • Connectors

Fault Code: B1328 15
Description of Fault: Rear screen and/or mirrors de-icing control fault: Open circuit or short circuit to positive. Detection of a short circuit to positive or of an open circuit (Impossible to activate the rear screen and/or door mirrors de-icing control).
Conditions of activation of the diagnostics
The following conditions have to be met:
- Engine running
- Controlled mode of the BSI output (Rear screen and/or mirrors de-icing control)
Conditions for Fault to clear:
  • Absence of a short circuit to positive or of an open circuit
Downgrade Modes whilst Fault is active:
  • Deactivation of the BSI output (Rear screen and/or mirrors de-icing control)
Symptoms:
  • Malfunction of the de-icing of the rear screen and/or mirrors
Suspect Areas:
  • Built-in systems interface
  • Passenger compartment fuse box (BFH3)
  • Relay "R1" of the passenger compartment fuse box (BFH3)
  • Electrical harness
  • Connectors

Fault Code: B132A 84
Description of Fault: Air conditioning circuit low pressure safety fault: Signal below the tolerance range. Low pressure safety active (For more than 1s).
Conditions for Fault to clear:
  • Low pressure safety inactive
Downgrade Modes whilst Fault is active:
Symptoms:
  • Malfunction of the production of cold air
  • Malfunction of the regulation of the requested temperature
  • Malfunction of the windscreen demisting/de-icing
Suspect Areas:
  • Air conditioning pressure sensor
  • Electrical harness

So I would also check the refrigerant - it that gets too low the compressor will cut off and the A/C won't work as a safety measure.

B1505 Again there are missing parts to the end of the code so could be lots of issues, but they indicate generally a short circuit to positive or earth. If you've had the unit out, check all the connectors at the rear as a pin could be loose.

B1000 Can't help with this as again missing the last 2 parts of the code and without this there is no way of telling what system this refers to - could be any ECU!
