Question 1

Manoeuvring system not working

Accepted Answer

Possible cause: Power supply failure or defective fuse in the battery cable. Check the power supply - the control unit's green LED should be lit. Replace any faulty fuse in the battery cable with a genuine spare part. Cut the power for at least 20 seconds, then restore it. Contact an authorised service agent if the problem persists.

Question 2

The manoeuvring system isn't working, and the control unit's red LED is flashing

Accepted Answer

Possible cause: Control unit is overheated. Turn off the battery cut-off switch and take the key out. Let the control unit cool for at least 20 minutes before restarting the manoeuvring system.

Question 3

The manoeuvring system isn't working, and both the red and green LEDs are flashing on the control unit

Accepted Answer

Possible cause: Overloading of the power electronics due to an overloaded caravan or excessive slope. Cut the power for at least 20 seconds, then restore it. Make sure the weight and slope limits haven't been exceeded.

Question 4

The manoeuvring system isn't responding to the remote control, or only responds intermittently

Accepted Answer

Possible cause: Remote control battery charge is too low or manoeuvring system battery is low. Check the remote control display symbols. Check the battery of the manoeuvring system, and charge or replace it if necessary.

Question 5

Drive roller sliding off tyre

Accepted Answer

Possible cause: Incorrect tyre pressure, worn tyre tread, or incorrect distance between tyres and drive rollers. Check the tyre pressure and adjust if needed, and check the tread and swap the tyres if needed. With the manoeuvring system disengaged, confirm the gap between the tyres and the drive roller measures 20mm.

Question 6

Manoeuvring system not disengaging

Accepted Answer

Possible cause: Electrical disengaging failure or discharged body battery. Disengage the manoeuvring system manually using the special spanner. If the issue remains unresolved, have repairs carried out by a specialist workshop.

Question 7

Error Red continuous-error symbol lights up steadily, with a beep: Persistent fault, such as a faulty drive motor.

Accepted Answer

Apply the parking brake. Then check the remote control's batteries, that it's paired with the control unit, that the 13-pin plug or adapter is properly in the safety socket, and that the caravan battery is charged and its fuse is intact. If none of that fixes it, contact Truma Service.

Question 8

Error Green radio symbol flashes rapidly with beeps, then the remote switches off: No radio connection within 10 seconds of switching on the remote control.

Accepted Answer

Make sure the control unit is switched on and the 13-pin plug or adapter is pushed into the safety socket, then turn the remote control on again.
