Question 1

Error x_x_x_x: ETS Plus blinking green (fast)

Accepted Answer

Possible cause: Brake intervention or auto-test. Possible to continue driving.

Question 2

Error x___x___: ETS Plus blinking green (short pulses)

Accepted Answer

Possible cause: In power-saving mode. You can continue driving - the system switches itself into ready mode after about 3 seconds.

Question 3

Error xxx__xxx__: ETS Plus blinking green (slow)

Accepted Answer

Possible cause: System or brakes too hot. Keep driving carefully - the cooling system will switch itself back into ready mode roughly 120 seconds later.

Question 4

Error _x_______: ETS Plus blinking red light

Accepted Answer

Possible cause: An electrical supply fault - a loose contact or too low a voltage, for example.. Check the plug-in cabling. Disconnect the system and leave it unplugged for a full 20 minutes before reconnecting it. If the fault's still there after that, contact a dealer or an authorised specialist.

Question 5

Error _x_x_____: ETS Plus blinking red light

Accepted Answer

Possible cause: A mechanical fault - no brake cable connected, badly worn brakes, or an incorrectly installed system, for example.. Visually inspect the brakes and the ETS Plus assembly, and confirm the braking system is properly adjusted. Disconnect the system and leave it unplugged for a full 20 minutes before reconnecting it. If the fault's still there after that, contact a dealer or an authorised specialist.

Question 6

Error _x_x_x___: ETS Plus blinking red light

Accepted Answer

Possible cause: An error in the central unit - the handbrake being on, or the brake rigging preloaded during assembly, for example.. Release the handbrake if needed (the overrun equipment should be fully extended), and check the brake rigging is properly adjusted if necessary. Disconnect the system and leave it unplugged for a full 20 minutes before reconnecting it. If the fault's still there after that, contact a dealer or an authorised specialist.

Question 7

ETS Plus LED does not light up

Accepted Answer

Possible cause: ETS Plus is inactive. Disconnect the 13-pin trailer cable from the tow vehicle and visually inspect the plug and its contacts. Confirm there's a steady positive supply at the socket, then reconnect the 13-pin cable. If that doesn't help, contact a dealer or authorised specialist.

Question 8

Noises occurring while towing the caravan

Accepted Answer

Possible cause: Could be:

1) a painted, dacromet-coated tow ball

2) a galvanised or varnished tow ball

3) a tow ball that's damaged, rusty, or dirty

4) friction pads in the hitch that are worn or dirty

5) dryness affecting the brake rod or towbar within the overrun equipment's linings.. For a tow ball that's painted, galvanised, varnished, damaged, rusty, or dirty, or for worn/dirty friction pads, check the sections covering the towing vehicle's tow ball and the hitch. If the towbar or brake rod has run dry, grease the bushings via the lubricating nipple, remove the gangway bellows to grease the exposed tow bar, and re-grease the tow ball where it sits on the locking mechanism, taking it off first.
