Cause
The anti-theft device is probably activated.
The RTI unit has detected an incorrect chassis number via the CAN bus.
The RTI unit has been moved to a different vehicle without the new vehicle’s chassis serial number being registered via SDP3.
After the battery power to the vehicle has been cut, the RTI unit has been started before the vehicle’s starter key has been turned to the drive position. This means that the RTI unit has not received CAN data.
Notes
If the theft protection is activated, a red LED is lit on the front of the RTI unit.
Action
Turn the starter key. When the power is turned on, the CAN bus should receive vehicle identity data.
If the RTI unit is moved to a new vehicle, the unit must be unlocked by SDP3.
