Setting for positive or negative polarity:
For positive polarity – Standard setting: Position the jumpers located on the bottom end of the
control module on the top two pins.
For negative polarity: Position the jumpers located on the bottom end of the control module on the
bottom two pins.
Programming the key fobs:
Make sure the system is unlocked and then disconnect the actuator with internal switch wire harness
from the control module prior to programming.
Press the program button on the side of the control module (3) times; the red LED will then light up.
Press button #1 on all of the key fobs that will be associated with the vehicle, (up to 4 key fobs),
within 10 seconds of the red LED lighting up. When the LED light goes off, the key fobs are then
programmed to the control module. Then, reconnect the actuator with internal switch wire harness to
the control module. Test each key fob by locking and unlocking the system to ensure proper
operation. NOTE: All key fobs must be programmed at the same time using this procedure.
Programming one key fob at a time will erase the previous programmed key fob.
