| 03F2 | Control unit Incorrect or unreliable data. The system is inoperative. | — |
| 03FC | Control unit There are no values in the EOL parameter memory. The system is inoperative. The fault occurs if a replacement control unit is fitted without programming the EOL parameters. AWD malfunction is on. | — |
| 07D0 | Control unit Incorrect or unreliable data. The system is inoperative. | — |
| 07DA | Control unit Incorrect or unreliable data. The system is inoperative. | — |
| 0BB8 | Control unit Incorrect or unreliable data. The system is inoperative. | — |
| 1388 | Control unit The supply voltage has been above 35 V. No solenoid valves will be actuated as long as the voltage is too high. The ones that had already been activated will remain so. When this fault is active, it prevents the generation of fault codes for the solenoid valves. | — |
| 1392 | Control unit The supply voltage has been below 20 V. As long as the voltage is below 20 V, solenoid valves will not be activated. The ones that had already been activated will remain so. The fault code is only generated when the engine speed is above 400 rpm. Therefore not during the starting procedure. | — |
| 2710 | Differential lock, front axle. The speed of the right and left wheels on front axle 1 are different despite the solenoid valve for the differential lock being active and the position sensor confirming that the differential lock is engaged. The driver is given an indication that the differential lock is engaged despite it not working. This fault code is generated if any of the wheels are slipping. | — |
| 2711 | Differential lock, transfer gearbox/front wheel drive The front axle speed and the vehicle speed are not the same despite the solenoid valve for the differential lock being active and the position sensor confirming that the differential lock in the transfer gearbox is engaged. The driver is given an indication that the differential lock is engaged despite it not working. This fault code is generated if any of the wheels are slipping. | — |
| 2B34 | CAN communication from the brake system One of the CAN messages expected from the BMS control unit disappears or is missing. The transfer gearbox differential lock cannot be disengaged by the ABS/EBS system. The driver must release the accelerator pedal to activate the differential lock. The fault code is only generated in vehicles with BMS. If fault codes 11060, 11070, (possibly 11080 or 11090 depending on vehicle specification), 11100 and 11110 have been generated, there is probably a break in the CAN cable to the AWD control unit. | — |
| 2B3E | CAN communication from tachograph One of the CAN messages expected from the tachograph disappears or is missing. If there is also a time-out from the brake system, it is possible to change gear in the transfer gearbox even though the vehicle is not stationary/almost stationary. The driver must release the accelerator pedal to activate the differential lock in the transfer gearbox. | — |
| 2B48 | CAN communication from automatic gearbox One of the CAN messages expected from the automatic gearbox control unit disappears or is missing. The engine must be switched off and the ignition turned off to change gear in the transfer gearbox. The fault code is only generated in vehicles with an automatic gearbox. If fault codes 11060, 11070, 11080, 11100 and 11110 have been generated, there is probably an open circuit on the CAN cable to the AWD control unit. | — |
| 2B52 | CAN communication from manual gearbox or OPC One of the CAN messages expected from the GMS control unit disappears or is missing. In vehicles with OPC or manual gearbox with acknowledgement for engaged neutral in the main gearbox, the clutch pedal must be depressed before changing gear in the transfer gearbox. The fault code is generated only on vehicles with acknowledgement for engaged neutral in the main gearbox. If fault codes 11060, 11070, 11090, 11100 and 11110 have been generated, there is probably an open circuit on the CAN cable to the AWD control unit. In vehicles with manual gearbox, the coordinator functions as a transmission control unit and transmits these messages. | — |
| 2B5C | CAN communication from the coordinator One of the CAN messages expected from the coordinator disappears or is missing. In vehicles with manual gearbox with acknowledgement for engaged neutral position or OPC, neutral must be engaged in the main gearbox before changing gear in the transfer gearbox. If there is no acknowledgement for neutral in the main gearbox, the ignition must be turned off before changing gear in the transfer gearbox. If fault codes 11060, 11070, (possibly 11080 or 11090 depending on vehicle specification), 11100 and 11110 have been generated, there is probably a break in the CAN cable to the AWD control unit. | — |
| 2B66 | CAN communication from engine control unit One of the CAN messages expected from EMS disappears or is missing. Deterioration in the safety features during drive wheel disengagement. Drive wheel disengagement can be activated even though the conditions relating to engine speed have not been met. If fault codes 11060, 11070, (possibly 11080 or 11090 depending on vehicle specification), 11100 and 11110 have been generated, there is probably a break in the CAN cable to the AWD control unit. | — |
| 36B1 | Low gear The position sensor changes the status from active to passive even though the solenoid valve is still activated. The driver is given an indication that low gear has been disengaged. The system attempts to maintain the current gear position. This fault code is generated only if the engine is running and has been running for at least five minutes. | — |
| 36B2 | Low gear The position sensor is activated without the solenoid valves being activated. The system retains the current activated gear position. | — |
| 36B3 | Unexpected difference in speed across transfer gear The difference in rotational speed between the transfer gearbox input shaft and the transfer gearbox output shaft is different from the rotational speed indicated by the gear ratio expected by the transfer gear. | — |
| 36BB | Differential lock for transfer box/front wheel drive. The position sensor changes the status from active to passive even though the solenoid valve is still activated. The driver is given an indication that the differential lock has been disengaged. The system attempts to engage the differential lock. This fault code is generated only if the engine is running and has been running for at least five minutes. | — |
| 36BC | Differential lock for transfer box/front wheel drive Acknowledgement from "central differential lock" position sensor without the function being activated. The driver receives an indication that the differential lock has been activated. | — |
| 36C4 | Differential lock for front axle 1 The position sensor changes the status from active to passive even though the solenoid valve is still activated.
