Engage Park Brake
There is an optional connection to a park brake switch that will turn this light on if the park brake
is released. If this is connected the light will be on. If the keypad is powered up and the park
brake is released, the light should go out if the park brake is applied. Not all manufactures of all
vehicles connect this to operate. If the park brake is applied and the light is on locate the black
wire with the yellow trace. On most units it will exit the harness near to the keypad connection.
On Four Winds (Thor) vehicles it will be in the area where the pump assembly is located. On
most units this wire can be found in a 2 pin connector with a pink wire. To test- locate the black
wire with the yellow trace. This wire is looking for ground to turn the light off. If this wire is
disconnected from ground the light will be on. If the wire is grounded the light should go off.
If the black/yellow wire is connected to ground and the light is on -check the wire back to the
connector at the controller. If the wire is good and the light will not go out then the controller is
defective. Also note that if this light is on, jacks will not extend from the manual down arrows
and Auto-Level will not function. If the wire is not being connected to ground when the park
brake is applied then there is an issue with the chassis side of the circuit.
Ignition ON
This light will be on if the ignition key is turned to the ON (engine run) position and the keypad
is powered up. The light should go off when the ignition key is in the off position. To test: locate
the pink wire- generally it will break out of the harness near the keypad. On Four Winds (Thor)
vehicles this wire will be near the pump assembly. It should have 12 VDC + applied to it when
the ignition key is on (engine run) position. There should be no voltage to it when the ignition
key is in the off position. If this is not correct the issue is with the connection to the chassis
harness or switch.
Excessive slope
This light will come on after an unsuccessful attempt of Auto-Level. Basically it means that the
system was unable to level the coach to within the specification of .5 degrees front to rear and
left to right. Or one or more of the jacks have run out of travel (maximum extension) prior to the
coach being level within the specified time allowance.
