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.
On a phone call, you cannot hear the call, but the caller can hear you. Make sure that the 4-pin green and white connectors in the harness are
plugged in correctly as stated in step 2.
The radio stays ON. Make sure the 2-pin connectors in the harness are connected as stated in
step 2.
The radio does not turn ON at all. Make sure the 2-pin connectors in the harness are connected as stated in
step 2.
If you have a multimeter, turn the key on and check for DC voltage at the
maestro’s heavy gauge 3-pin plug (red, yellow, and black wires). The Maestro
must be plugged in to get an accurate measurement. If there is 12 volts on
the red and yellow, the Maestro is working correctly and sending power out
to turn on the radio. If no voltage on either, check the inline fuse and then
the vehicle’s fuse for the radio circuit.
The light on the Maestro is fl ashing RED ONCE. There is no fi rmware on the module; fl ash the RR module.
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 fl oating screen type 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.
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.
