TROUBLESHOOTING TABLE
PROBLEM
SOLUTION
Gauges do not work, radio shows OBD2 Error 1 or Error 2.
Ensure OBDII connector is securely attached to the OBDII connector of the
vehicle.
If you hardwired connections at the OBDII, check connections at the OBDII
connector. Make sure the
RED/BROWN
wire is on
PIN 6
and the
YELLOW/
BROWN
wire is connected to
PIN 14
of the OBDII connector. Do not use
T-Taps. Soldering or military splicing methods are recommended.
If anything else is connected to the OBD2 or CAN wires of vehicle
(programmer, throttle controller, insurance tracker, etc.) try unplugging it to
see if gauges work. If gauges work without it installed, call tech support for
options.
Reset the RR.
The light on the Maestro is blinking
RED TWICE
and the radio
IS
turning on.
Ensure the 4-pin data cable is connected between the radio and the RR, and
that it is plugged into the black port on the Maestro RR. The red and blue
ports on the RR should be empty.
Make sure the correct radio model and serial number were entered during
the fl ash. Verify the radio’s serial number entered during the fl ash matches
what is listed on the radio screen. This can be found in the settings of the
radio, listed as Device Id, Device Number, or Serial Number.
The light on the Maestro is blinking
RED TWICE
but the radio is
NOT
turning
on.
If installing a modular radio and it is not turning on, ensure the screen is
secured and any trim pieces on the radio have been installed fully. Not
installing these fully will prevent radio from powering up and show a 2x red
error as well.
Test red and yellow wires for DC voltage at radio using a multimeter. Contact
support if no voltage on red or yellow.
The light on the Maestro is fl ashing
RED ONCE
.
There is no fi rmware on the module; fl ash the RR module.
The Harman Kardon system has no sound. (if applicable)
Ensure the
BLUE/WHITE
amp turn-on wire is connected. Ensure the 6-pin
connector (the plug with blue, green, green/black, purple, and purple/black
wires) on the T-harness is not connected to the car.
MAESTRO RR2 RESET PROCEDURE:
Turn the key to the OFF position, then disconnect all connectors from the module.
Press and hold the module’s programming button and connect all the connectors back to the module. Wait, the module’s LED will fl ash RED rapidly (this may
take up to 10 seconds).
Release the programming button. Wait, the LED will turn solid GREEN for 2 seconds to show the reset was successful.
