Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
LED 2 (yellow) illuminates | Short-term fault occurs, accompanied by an acoustic signal due to overcurrent or high temperature. Possible Cause: System is overheating or experiencing temporary overcurrent. | Allow the system to cool down. Power is automatically reduced. | DIY Safe |
LED 2 (yellow) flashes | Mover is engaged and the control unit or remote control was switched off, or previous engagement/disengagement process was incomplete. Possible Cause: Control unit or remote powered off while rollers were engaged, or engagement process interrupted. | Restart the engagement or disengagement process and complete it fully before executing drive commands. | DIY Safe |
LED 3 (red) illuminates | Persistent system error or faulty drive motor, accompanied by an acoustic signal. Possible Cause: A permanent fault such as a drive motor failure or severe system error has occurred. | Apply the parking brake. Switch off the remote control for 2 seconds and switch it back on. If the fault persists, perform a reset for approx. 10 seconds (disconnect the leisure battery briefly or disconnect and reconnect the safety plug). If this does not resolve the issue, contact an authorised service agent. | DIY Check / Tech Fallback |
Operational Fault | Radio connection not established after switching on the remote control. Possible Cause: Remote control has not linked to the control unit. | Ensure the 13-pin plug/adapter is plugged into the safety socket on the caravan and check battery power. If connection fails within 10 seconds, the remote will switch off. | DIY Safe |
N/A | No LEDs illuminate and no acoustic signal sounds. Possible Cause: System is switched off, remote batteries are dead, or caravan battery is completely discharged / disconnected. | Check the remote control batteries and replace them if necessary. Check the caravan battery state of charge and inspect the fuse in the battery connection cable. | DIY Safe |
N/A | Manoeuvring system not working Possible Cause: Power supply issue or defective fuse in the battery cable | Check the power supply ensuring the green LED of the control unit lights up. Replace a defective fuse in the battery cable of the manoeuvring system only with an original spare part. Interrupt the power supply for at least 20 seconds, then restore it. If the issue remains unresolved, contact an authorised service agent. | DIY Check / Tech Fallback |
N/A | Manoeuvring system not working and red LED on control unit flashing Possible Cause: Control unit is overheated | Interrupt the power supply with the battery cut-off switch and remove the key. Allow the control unit to cool down for at least 20 minutes, then restart the manoeuvring system. | DIY Safe |
N/A | Manoeuvring system not working, red and green LED flashing on the control unit Possible Cause: Overloading of the power electronics due to an overloaded caravan or excessive slope | Interrupt the power supply for at least 20 seconds, then restore the power supply. If the issue persists, reduce the load or slope angle. If the problem continues, have repairs carried out by a specialist. | DIY Check / Tech Fallback |
N/A | Manoeuvring system not responding to commands from remote control or only with interruptions Possible Cause: Remote control battery charge is too low, manoeuvring system battery low, or radio interference | Check the battery of the remote control and replace if necessary. Check the battery of the shunting system; charge or replace the battery if necessary. Reduce the distance between the remote control and caravan. | DIY Safe |
N/A | Drive roller sliding off tyre Possible Cause: Incorrect tyre pressure, worn tyre tread, or incorrect distance between tyres and drive roller | Check the tyre pressure and adapt if necessary. Check the tyre tread and change the tyres if necessary. Disengage the manoeuvring system and measure the distance between the tyres and drive roller, which must be 20 mm. If incorrect, have the distance adjusted by a specialist workshop. | DIY Check / Tech Fallback |
N/A | Manoeuvring system not disengaging Possible Cause: Electrical disengagement failure or power supply interruption | Disengage the manoeuvring system manually using the special spanner. If the fault persists, contact an authorised service agent. | Professional Intervention Required |
