Touch Sensors
A pinch or Touch Sensor is installed on the left and right inner edge of the rear gate. If either sensor
is compressed during closing, the PRG automatically reverses and moves to the open position.
Touch Sensor
The touch sensor is constructed in a soft rubber tube, consisting of 4 spiral wound wires. The
wires are coated with a semi-conductive coating that allows the wires to act as a switch. When
the tube or sensor is compressed, the wires will touch each other and lower the resistance in the
pinch circuit. The more the wires are compressed, the lower the resistance becomes.
Touch Sensor Tube Touch Sensor Resistor
A resistor (approximately 975 ohms) is connected in parallel with the touch sensor so that the touch
sensors can be monitored by the PRG control unit. If either sensor is not connected, or has the
incorrect resistance, a DTC will set and the PRG will not function (manual mode will be available).
Warning: Keep away from the closing area of the rear gate (PRG). The outer edge of the rear
gate (PRG) beyond the touch sensor cannot detect solid objects and will not trigger a safety
maneuver until the amperage of the rear gate (PRG) exceeds pre-established specifications.
