Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 4
- CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - DCM (TELEMATICS TRANSCEIVER))
- Check the installation condition.
- Check the USB communication lines between the radio receiver assembly and DCM (telematics transceiver) for any installation or connection problems.
- Disconnect the G119 radio receiver assembly connector.
- Disconnect the G130 DCM (telematics transceiver) connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G119-1 (USB+) - G130-2 (USB+) Always Below 1 Ω G119-2 (USB-) - G130-1 (USB-) Always Below 1 Ω G119-3 (USBS) - G130-3 (USBS) Always Below 1 Ω G119-1 (USB+) or G130-2 (USB+) - Body ground Always 10 kΩ or higher G119-2 (USB-) or G130-1 (USB-) - Body ground Always 10 kΩ or higher G119-3 (USBS) or G130-3 (USBS) - Body ground Always 10 kΩ or higher *a Front view of wire harness connector

Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 5
- Check the installation condition.
- REPLACE DCM (TELEMATICS TRANSCEIVER)
- Replace the DCM (telematics transceiver) with a new one.
Refer to REMOVAL [10/2019 - 08/2020] , or refer to REMOVAL [08/2020 - 09/2022]
- Clear the DTCs.
Body Electrical > Navigation System > Clear DTCs
- Turn the engine switch off.
- Turn the engine switch on (IG) and wait for 90 seconds.
- Recheck for DTCs and check that no DTCs are output.
Body Electrical > Navigation System > Trouble Codes
OK
No DTCs are output.
Result
Proceed to OK NG
Result:
OK
END
Result:
NG
REPLACE RADIO RECEIVER ASSEMBLY. Refer to REMOVAL [06/2018 - 08/2020] , or refer to REMOVAL [08/2020 - 09/2022]
- Replace the DCM (telematics transceiver) with a new one.
