Faults found on the Bosch ABS system mounted on class B

1. ABS fault, ABS warning light on and does not come into operation (power supply errors)
2. ABS does not communicate the diagnoses and the lack of communication error is recorded on the other control units in the network
3. Ferenata unbalance defects (very rare)

Initial medical history:

1. The message "eps fault go to workshop" appears on the instrument cluster display. Red abs and yellow esp lights on, sometimes lacks power.
2. ABS and ESP warning lights on
3. Unbalanced braking (braking defect on one or more wheels that lock without braking)
4. The speedometer does not work
5. failure to communicate or faults on the CAN network
6. Pump motor malfunction or power supply errors

Power failures are mainly due to water infiltration into the fuse box which is located under the passenger's feet. By removing the fuses you can see the oxide.
