290 Error by Safety Controller (AD-setpoti 1 uC1 - uC2 difference )
291 Error by Safety Controller (AD-actpoti 1 uC1 - uC2 difference )
292 Error from Safety Controller (powerstages uC1 - uC2 differs)
293 Error from Safety Controller (dig. input uC1 - uC2 differs)
294 Error from Safety Controller (dig. output uC1 - uC2 differs)
295 Error from Safety Controller (srwsangle uC1 - uC2 differs)
296 Error from Safety Controller (Voltage Entraction uC1 - uC2 differs)
299 Common error by Safety Controller
6.6.4 Safety steering error codes:
Information codes
1 Power-Up -Tests not finished (ext. Safetyrelay open but should be closed)
2 Power-Up -Tests not finished (Safetyrelay open but should be closed)
3 Controller set to Passivemode by CAN-Flasher
7 Unteached Potentiometer or corrupped EEProm
8 incorrect EEProm truckidentifer value
Warning codes
No codes implemented
Error codes
220 no Productiontest (--OK--sign missing in EEPROM)
240 Fatal plant behaviour error: Steering angle varies in the opposite direction to the commanded one (PWM). One
of those components does not work properly: PWM unit, inverter, motor, gear or angle sensor or the steering
axle is externally actively moved (should not occur normally)
242 ext. Safetyrelay open but should be closed
243 Safetyrelay open but should be closed
244 Error from internal communication between controllers (SSC Watchdog)
245 EnableTraction voltage wrong
