Parameters, Status
When taking a readout of signals activated by the trailer module (TRM), there should not be any trailer connectors plugged into the socket of the vehicle's tow hitch. The trailer connector may only be plugged into the socket if the cable harness and its connectors are checked and fault-free.
The socket for the tow hitch connector is available in several variants with different numbers of poles. The output signals for back-up (reversing) lamps, fog lamps and charging (+12 V) is market dependent.
TRAILER CONTACT CONNECTED
Indicates if the trailer module (TRM) registers that the tow hitch connector is connected to the socket.
Yes = tow hitch connector is connected.
No = tow hitch connector is not connected.
BACK UP LIGHT
Indicates if the trailer module (TRM) has activated the signal for the back-up (reversing) lamp.
On = back-up (reversing) lamp activated.
Off = back-up (reversing) lamp not activated.
FOG LIGHTS
Indicates if the trailer module (TRM) has activated the signal for the fog lamp.
On = fog lamp activated.
Off = fog lamp not activated.
LEFT PARKING LAMPS
Indicates if the trailer module (TRM) has activated the signal for the left parking lamps.
On = left parking lamps activated.
Off = right parking lamps not activated.
RIGHT PARKING LAMPS
Indicates if the trailer module (TRM) has activated the signal for the right parking lamps.
On = right parking lamps activated.
Off= right parking lamps not activated
STOP (BRAKE) LAMPS
Indicates if the trailer module (TRM) has activated the signal for the brake lamp.
On = brake lamp activated.
Off = brake lamp not activated.
BRAKE LAMP CAN SIGNAL
Indicates if the trailer module (TRM) receives CAN signals for the brake lamp.
On = CAN signals for brake lamp received.
Off = CAN signals for brake lamp not received.
BRAKE LAMP HW SIGNAL
Indicates if the trailer module (TRM) receives HW signals for the brake lamp.
On = HW signals for brake lamp received.
Off = HW signals for brake lamp not received.
LEFT TURN SIGNAL LAMP
Indicates if the trailer module (TRM) has activated the signal for the left-hand turn signal lamp.
On = left-hand turn signal lamp activated.
Off = left-hand turn signal lamp not activated.
RIGHT TURN SIGNAL LAMP
Indicates if the trailer module (TRM) has activated the signal for the right-hand turn signal lamp.
On = right-hand turn signal lamp activated.
Off = right-hand turn signal lamp not activated.
CHARGING
Indicates if the trailer module (TRM) has activated the signal for charging (+12 V).
On = charging (+12 V) activated.
Off = charging (+12 V) not activated.
