Troubleshooting
FOB Testing
NOTE: The module LED should flash in a heartbeat pattern during normal operation.
After (1) hour, the LED turns off and enter sleep mode.
1.
Press and release FOB button to unlock passenger door. The module LED should FLICKER flash
every (1) second and will be brighter.
2.
If the module LED FLICKER flashes (2) seconds, the FOB signal is received but the FOB is
NOT paired. See
Adding a New FOB
to pair a FOB to module
.
3.
If the LED FLICKER flashes (8) seconds or more, the FOB signal is received and FOB is paired.
4.
If LED does NOT FLICKER flash (maintains heart beat pattern only), then no transmission is
being received (FOB or module malfunction).
5.
Use a FOB paired to another vehicle to repeat steps 1-3. If module LED FLICKER flashes with
FOB pair to another vehicle, the original FOB is NOT transmitting.
6.
Replace battery on FOB and repeat test. If no change in heartbeat LED after new battery, FOB is
malfunctioning.
Note: It is NOT necessary to pair a FOB after the battery is replaced. The pairing data
is stored in non-volatile memory on the FOB.
7.
If the LED does not FLICKER flash with known good FOB, module is defective.
