Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
Manoeuvring system not working (Green LED on control unit off) | Lack of power supply or blown fuse. | — | Check the power supply and the battery cable's fuse - if the fuse has blown, replace it only with a genuine Truma spare. Otherwise, cut the power for at least 20 seconds and then restore it. | DIY Safe |
Manoeuvring system not working, red LED on control unit flashing | Control unit is overheated. | — | Cut the power with the battery isolator switch, take the key out, and give the control unit at least 20 minutes to cool before you start again. | DIY Safe |
The manoeuvring system isn't working, and the control unit's red LED is flashing | Control unit is overheated. | — | Turn off the power at the battery isolator, take out the key, and leave the control unit at least 20 minutes to cool before restarting. | DIY Safe |
Mover not working - control unit's red LED flashing | Control unit is overheated. | — | Switch the power off at the battery isolator and remove the key, then wait at least 20 minutes for the control unit to cool before using it again. | DIY Safe |
Mover not working - control unit's red and green LEDs flashing | Overload of the power electronics due to an overloaded caravan or too steep a slope. | — | Cut the power for at least 20 seconds, then switch it back on. | DIY Safe |
Manoeuvring system not responding or working only with interruptions (Red LEDs on remote flashing) | The remote control's battery is low. | — | Check the remote's battery and its contacts - fit a new battery and/or clean the contacts. | DIY Safe |
System does not respond or responds intermittently, red LEDs on remote control flashing | The remote control's battery is low. | — | Check the remote control battery and contacts. Replace the battery or clean the contacts if necessary. | DIY Safe |

Then disengage the system and measure the gap between each tyre and its drive roller - it must be 20 mm. | DIY Safe |
Maneuvering system does not work (Green LED on control unit is off) | Lack of power supply or blown fuse in the battery cable. | — | Check the power supply and that the control unit's green LED is lit. If the battery-cable fuse has blown, replace it only with a genuine Truma part. Cut the power for at least 20 seconds and then restore it. | DIY Safe |
Mover not working, red LED on the control unit flashing | The control unit is overheated. | — | Turn the power off at the battery switch and pull the key out, then let the control unit cool for at least 20 minutes before starting again. | DIY Safe |
Control unit red LED is blinking | The control unit is overheated. | — | Cut the power at the battery isolator and take the key out, then leave the control unit at least 20 minutes to cool before restarting. | DIY Safe |
Maneuvering system does not work, red and green LEDs on control unit are flashing | Overload of the power electronics (e.g., overloaded caravan, excessive gradient). | — | Cut the power for at least 20 seconds, then turn it back on. | DIY Safe |
Green LED on control unit is flashing | Weak battery in the maneuvering system. | — | Check the maneuvering system battery; charge or replace it if necessary. | DIY Safe |
Drive roller slips over the tire | Incorrect tire pressure, worn tire tread, or incorrect roller-to-tire distance. | — | Check the tyre pressures and adjust them, check the tread, disengage the rollers and measure the tyre-to-roller gap (it must be 20 mm). | DIY Safe |
Manoeuvring system not working | Power supply issue, green LED on control unit is off, or defective fuse in the battery cable. | — | Check the power supply and the battery cable's fuse (only ever replace it with a genuine Truma spare), then cut the power for at least 20 seconds and restore it. | DIY Safe |
Mover not working - control unit's red and green LEDs flashing | Overloading of the power electronics (e.g., overloaded caravan, excessive slope). | — | Cut the power for at least 20 seconds, then reconnect it. | DIY Safe |
Mover doesn't respond to the remote, or only intermittently | The remote's battery is low (red LEDs flashing), or the Mover's battery is low (the control unit's green LED flashes). | — | Check and replace remote control battery, clean battery contacts, or charge/replace the shunting system battery. | DIY Safe |
Maneuvering system does not work, control unit green LED is off | Power supply issue or blown fuse in the battery cable. | — | Check the power supply and that the control unit's green LED is lit. Only replace a blown fuse with a genuine Truma part. Then cut the power for at least 20 seconds and restore it. | DIY Safe |
Red and green LEDs on control unit are blinking alternately | Overload of the power electronics due to an overloaded caravan or steep inclination. | — | Disconnect the power for at least 20 seconds, then reconnect it. | DIY Safe |
Mover not running | Check power supply (green LED on controller should be lit). Fuse in Mover battery connection cable may be damaged. | — | Replace blown fuse only with Truma original spare part (part no. 60040-00169) or interrupt power for at least 20 seconds and restore. | DIY Safe |
Mover not running & red LED flashing on controller | Controller is overheated. | — | Disconnect power using the battery isolation switch and remove key. Allow controller to cool for at least 20 minutes before operating again. | DIY Safe |
Mover does not respond to remote or intermittent response | Low battery on remote control (red LED on remote flashes) or low Mover battery (green LED on controller flashes). | — | Check remote batteries/contacts and replace if necessary, or charge/replace the Mover battery. | DIY Safe |
Drive roller slips from tire | Incorrect tire pressure, worn tire tread, or incorrect distance between tire and drive roller. | — | Check and adjust tire pressure, replace worn tires, or re-measure distance to ensure it is exactly 20 mm. | DIY Safe |
Mover does not engage on one side (Mover smart A only) | Power supply or remote interrupted during engagement sequence, or mechanical load relief process incomplete. | — | Ensure power is not interrupted and wait for indicator lights to stop flashing.

Frequently Asked Questions
Q: What is the maximum weight and gradient the Mover smart M RS1 can handle?
It's built for single-axle caravans up to 2000 kg gross weight, and will climb slopes of up to 13% at 2000 kg (or 25% at 1200 kg).
Q: How do I engage the drive rollers against the tyres?
Push the supplied engagement lever completely onto the toggle crank and turn it towards the vehicle wheel until the engagement mechanism securely clicks in and the status display points to the correct symbol.
Q: What should I do if the remote control loses connection or needs to be paired?
Establish power via the battery cut-off switch, press the reset knob on the control unit with a thin object until the green and red LEDs flash alternately, and then switch on the remote control using the green ON button to pair automatically.
Q: How do I turn on the remote control?
Hold down the green ON button until its LED comes on.
Q: What should I do if the remote control and control unit lose synchronization?
Ensure the battery is properly connected with 12V applied and rollers disengaged. Switch on power via the battery switch, press the reset button on the control unit using a thin object until alternating green and red LEDs flash, then press the green ON button on the remote control to automatically synchronize.
