What to do if gauges do not work and radio shows OBD2 Error 1 or Error 2 with iDataLink Maestro RR2?
- MMark KimAug 17, 2025
If your gauges aren't working and the radio displays OBD2 Error 1 or Error 2, ensure the OBDII connector is securely attached to the vehicle's OBD2 connector. If you've hardwired connections at the OBDII, double-check these connections. Make sure the RED/BROWN wire is on PIN 6 and the YELLOW/ BROWN wire is connected to PIN 14 of the OBDII connector. Soldering or military splicing methods are recommended. If other devices are connected to the OBD2 or CAN wires (like programmers or insurance trackers), try unplugging them to see if the gauges then work. If they do, contact tech support for options and reset the RR.
