TROUBLESHOOTING TABLE
PROBLEM SOLUTION
Gauges do not work, radio shows OBD2 Error 1 or Error 2. 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.
The light on the Maestro is blinking RED TWICE. 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 fl ashing RED once. There is no fi rmware on the module; fl ash the RR module.
There is no sound from OEM sources like OEM satellite radio. Ensure the all black, 3-pin to 3.5mm audio cable is connected between the
RR and the radio. Make sure it is in the correct radio input.
The steering wheel controls are not working, the Maestro RR does not blink
when they are pressed.
Ensure the 20 or 28-pin connector is plugged to the vehicle and to the TO1
T-harness, as shown in step 3 (this is where the RR gets the steering wheel
signal from the vehicle).
(Prius only) After the car is turned off, the radio stays on. The car stays in
accessory mode and will not turn off.
Locate the white 12-pin connector of the TO1 harness, it is connected to the
vehicle harness.
Then, cut and isolate the red wire located at pin 11. The radio will shut off
when the vehicle is turned off.
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. 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.
