TROUBLESHOOTING TABLE
PROBLEM SOLUTION
Gauges do not work, radio shows OBD2 Error 1 or Error 2. Ensure the 2 pin BLACK connector with the BROWN/YELLOW and BROWN/
RED wires is connected to the mating BLACK 2 pin connecto coming off the
OBDII harness and check for any terminals that may have been pushed out
when connecting the two.
Make sure the colors line up at the BLACK 2 pin connectors; BROWN/
YELLOW should line up with YELLOW and BROWN/RED should line up with
RED.
Make sure the OBDII connector is seated properly on the OBDII connector of
the vehicle.
If you hardwired the connections at the OBDII, check the connections at the
OBDII connector. Make sure the RED wire is on PIN 6 and the YELLOW wire
is connected to PIN 14 of the OBDII connector.
Do not use T-Taps.
Soldering or military splicing methods are recommended.
If the vehicle has anything plugged into the OBDII connector the Maestro RR2

Reset the RR2.
The light on the Maestro is blinking RED TWICE. Ensure the 4-pin data cable is connected between the radio and the RR2 in
the correct location (on the RR2 the Data cable plugs into the BLACK 4 pin
port),
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 info screen. This can be found in the settings of
the radio, listed as Device Id, Device Number, or Serial Number.
Make sure the radio is powering up.
The light on the Maestro is flashing RED ONCE. There is no firmware on the module; flash the RR2 module.
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 flash RED rapidly (this may
