Citroen C4 picasso 2011 Abs fault c1381

Unread post by shadow »

The car has all the braking related indication lights , i used diagbox to read the faults and it has the c1381 recirculation pump power supply fault , i replaced the esp ecu and all the cables also the voltage regulator in the alternator , i checked all the fuses and relays , and check all the voltages . The fault disappears after i restart the car but comes back on when the car reaches 30 km/h ,
Before reaching 30 km/h both the esp and abs is working fine, i also ran the tests that diag box have and everything seems normal and i cleaned all the speed sensors .
If someone knows how to fix that please help cause citroen authorized service didnt !
