PROBLEM Gauges do not work, radio shows OBD2 Error 1 or Error 2.
The light on the Maestro is blinking RED TWICE.

Reset the RR.
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 flash. Verify the radio's serial number entered during the flash 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.
There is no firmware on the module; flash the RR module.
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.

SuBaRu OutBack WIthOut aMPlIfIeR 2018-2022

PROBLEM Gauges do not work, radio shows OBD2 Error 1 or Error 2.
The light on the Maestro is blinking RED TWICE.
The light on the Maestro is flashing RED ONCE. The Harman Kardon system has no sound. (if applicable)

SOLUTION
Ensure OBDII connector is securely attached to the OBD2 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.
Reset the RR.
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 flash. Verify the radio's serial number entered during the flash 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.
There is no firmware on the module; flash the RR module.
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 RR 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.
