SYSTEM FAULTS AND REACTIONS

Malfunction Fault response
CAN steering angle signal correction Deviation > 10° Fixed current, fault in memory, gong at end of trip
Acceleration sensors (front, left, right, rear) Fixed current output for front axle, rear axle Fault in memory, gong at end of trip
Wheel speed front left/right
  1. Control operation with replacement sensor
  2. Fixed current output for front and rear axles
External voltage supply fault fluctuation (nominal should be 5 V +/- 10%) Fixed current output for front axle, rear axle Fault in memory, gong at end of trip
Voltage supply to EDC control module between 2 V and 8 V Valves de-energized, fault in memory, gong During trip
   
Valve failure Valves de-energized, fault in memory, gong during trip
Voltage wake up,<2V standing & wake up>7V Valves de-energized, fault in memory, gong during trip
No vehicle speed via CAN Bus Fixed current, fault in memory, gong at end of trip
Control module EEPROM faulty Fixed current, fault in memory
Control module - no alive message from EDC-K Valves de-energized, fault in memory, gong during trip
