| CHECK RADIO RECEIVER ASSEMBLY |
Disconnect the R2 receiver connector.
Measure the resistance and voltage of the wire harness side connector.
If the results are not as specified, there may be a malfunction on the wire harness side.Symbols (Terminal No.) Wiring Color Terminal Description Condition Specified Condition GND (R2-7) - Body ground BR - Body ground Ground Always Below 1 Ω ACC (R2-3) - Body ground GR - Body ground ACC power supply Ignition switch ACC 10 to 14 V B (R2-4) - Body ground L-Y - Body ground Battery power supply Always 10 to 14 V ILL+ (R2-10) - Body ground G - Body ground Illumination signal Light control switch TAIL 10 to 14 V Reconnect the R2 receiver connector.
Measure the voltage of the connector.
