Symptom : Qube is not powering up (All LEDs Off)
(Keep in mind, during initial installation, improper ignition wire connection may prevent the Qube from waking up/coming online)
1. Cycle ignition key Off/ON to attempt to wake up the Qube.
2. Are the GPS and Cell LED’s on? Check OnlineAVL2, if vehicle is reporting correctly, then the green Power LED is out of order (this does not affect
overall performance of the Qube).
3. Disconnect any accessories (M-Nav, MDT, etc) and the ConEx harness from the Qube to eliminate possibility of other devices causing short circuit.
4. Use multimeter to test wiring harness: verify that you are rec12V power, ignition and ground signals all the way at the Qube’s
connector/plug – at the pins. If this test fails, replace blown fuses, fix wire to wire connections or replace the harness. Perform device test at
vehicle’s battery.
5. Make sure all unused wires from the Qube’s harness are individually isolated/taped (cut off tinned ends off all unused wires).
6. Perform Cold Reset (see previous pages for this procedure).
7. If a spare/working Qube is available, plug it in to verify that its green Power LED comes on and it starts reporting in OnlineAVL2,
If the spare Qube works, remove the original Qube from vehicle for replacement. If the spare Qube does not power up, there could be an “open” or
“short circuit” in the existing wiring: replace all Qube’s power wiring, including the main harness, fuses and fuse holders.
If the spare Qube is not available, remove the original Qube from vehicle for replacement.
