The TTM offers a battery charge output. This
output is used for loading a trailer battery with a
maximum parameter current of 10A. If the current
exceeds 10A the output is switched off until the
current drain goes below 10A. The voltage used
to charge this battery is designed to maintain
current charge up to 10A but not fully charge the
battery or let it discharge. This voltage is
approximately 13.5V. Full charge strategy should
be performed separately.
The maximum total current is 30A of all circuits.
If this is exceeded the battery charge output is
switched off.
Summary:
•
Max permanent current: 10A
•
Switch on condition:
– Power Mode > = Accessory_1
– Total power consumption (all
battery charge) < 30A
– Permanent battery charge output current <
= 10A
– 9V < TTM power supply voltage < 16V
•
Short circuit detection: 30A
If trailer tow system is to be added, the correct
wiring and module needs to be ordered. The
vehicle needs to have Central Car Configuration
(CCC) programmed to the correct parameters:
CCC Parameter 20
•
0x1 without trailer tow
•
0x5 with trailer tow
NOTE: It is mandatory that a trailer is detected.
Therefore at least one of the following lights have
to be connected in the
on mode or in the stand
by mode (anti-theft mode): Stop right, Stop left,
Position lights or Direction indicator left.
If a trailer is detected the trailer detection
hardware output (JP3-pin 5) is set low (open
drain).
If a short circuit is detected or an overheating of
the drivers occurs, the related output remains off
until an ignition cycle is performed and the engine
is restarted.
The trailer detection uses a strategy of having a
1K ohm resistor if the lights are not actually
switched on to detect that the trailer has been
connected. If a trailer light is already switched on
the related current will be checked.
