TROUBLESHOOTING TABLE
PROBLEM SOLUTION
Gauges do not work, radio shows OBD2 Error 1 or Error 2. Ensure the 2-pin CAN extension harness is securely attached to the green
CAN junction block behind glove box.
Reset the RR.
When making 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 doesn’t turn ON at all. 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.
If front speakers have been replaced, ensure the wiring harness on the left
front speaker assembly has been reconnected. CAN passes through this
connector to get to the radio.
The radio illumination or other functionality isn’t working. Ensure the 2-pin CAN extension harness is securely attached to the green
CAN junction block behind glove box.
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.
The light on the Maestro is fl ashing
RED ONCE. There is no fi rmware on the module; fl ash the RR module.
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.
