ACUB1
| Code | Heading | Variants |
|---|---|---|
| 0200 | Fault detected in internal memory of the ECU. The following memory types are checked for faults: • program flash • calibration flash • internal RAM • EEprom emulated in flash • Stack memory | 2× |
| 0201 | The ECU software continuously performs checks for unexpected or illegal events. The DTC is set if such an event is detected. | 2× |
| 0202 | Overload in CPU or stack memory is detected. | 2× |
| 0203 | Memory used to store configuration data is inconsistent. | 2× |
| 0204 | ECU identification data has been lost. Examples of lost data are ECU complete number and vehicle identification number. | 2× |
| 0205 | Operation data stored in the persistent memory has been lost. | 2× |
| 0206 | End-of-line (EOL) parameter values have been lost. | 2× |
| 0208 | Communication error on HCU CAN bus. CAN-bus buffer overflow. | 2× |
| 0209 | Communication error. The CAN-controller of the HCU CAN bus has entered state bus-off. There might be a short circuit on the HCU CAN bus | 2× |
| 020A | Communication error on Sensor CAN bus. CAN-bus buffer overflow. | 2× |
| 020B | Communication error. The CAN-controller of the Sensor CAN bus has entered state bus-off. There might be a short circuit on the HCU CAN bus | 2× |
| 021E | Communication error on Automation B CAN bus. CAN-bus buffer overflow. | 2× |
| 021F | Communication error. The CAN-controller of the Automation B CAN bus has entered state bus-off. There might be a short circuit on the HCU CAN bus | 2× |
| 0220 | Communication error on InterSAGA CAN bus. CAN-bus buffer overflow. | 2× |
| 0221 | Communication error. The CAN-controller of the InterSAGA CAN bus has entered state bus-off. There might be a short circuit on the HCU CAN bus | 2× |
| 0222 | Arb rear hold valve PWM output is short circuit to ground | 2× |
| 0223 | Arb rear hold valve PWM output is short circuit to battery or open load | 2× |
| 0224 | Arb rear hold valve PWM output is short circuit to battery or open load, or short circuit to ground | 2× |
| 0225 | Arb front activation valve PWM output is short circuit to ground | 2× |
| 0226 | Arb front activation valve PWM output is short circuit to battery or open load | 2× |
| 0227 | Arb front activation valve PWM output is short circuit to battery or open load, or short circuit to ground | 2× |
| 0228 | XPD Self-test failed | 2× |
| 0229 | Electrical error detected on the emergency automation cut-off button or ACOS hardware. This can be caused by either electrical or mechanical faults. | 2× |
| 022A | Input parameters of ARB is out of range such as arb mode, arb hold rear limit, vehicle weight axles, parking brake pressure array, parking brake force array, expected pressure array and expected force array | 2× |
