Result
Result Proceed to w/ Navigation System A w/o Navigation System B
Result:
B
See step 4
Result:
A
See step 2
- Choose the model to be inspected.
- CHECK FOR DTC (NAVIGATION SYSTEM)
- Check if navigation system DTCs are output.
Body Electrical > Navigation System > Trouble Codes
Result
Result Proceed to DTCs are not output A DTCs are output B
Result:
B
GO TO NAVIGATION SYSTEM. Refer to DIAGNOSTIC TROUBLE CODE CHART [08/2021 - 09/2022]
Result:
A
See step 3
- Check if navigation system DTCs are output.
- CHECK FOR DTC (COMBINATION METER ASSEMBLY)
- Disconnect the G3 radio receiver assembly connector.
- Check if combination meter system DTCs are output.
Body Electrical > Combination Meter > Trouble Codes
HINT:
If DTC 132187 is output by the meter and gauge system, it can be judged that the radio receiver assembly could perform local bus communication line diagnosis, therefore the meter and gauge system may not be malfunctioning.
Result
Result Proceed to DTC B132187 is not output A DTC B132187 is output B
Result:
A
REPLACE COMBINATION METER ASSEMBLY. Refer to REMOVAL [08/2021 - ]
Result:
B
See step 6
- CHECK FOR DTC (AUDIO AND VISUAL SYSTEM)
- Check if audio and visual system DTCs are output.
Body Electrical > Navigation System > Trouble Codes
Result
Result Proceed to DTCs are not output A DTCs are output B
Result:
B
GO TO AUDIO AND VISUAL SYSTEM. Refer to DIAGNOSTIC TROUBLE CODE CHART [08/2021 - 09/2022]
Result:
A
See step 5
- Check if audio and visual system DTCs are output.
- CHECK FOR DTC (COMBINATION METER ASSEMBLY)
- Disconnect the G4 radio receiver assembly connector.
- Check if combination meter system DTCs are output.
Body Electrical > Combination Meter > Trouble Codes
HINT:
If DTC 132187 is output by the meter and gauge system, it can be judged that the radio receiver assembly could perform local bus communication line diagnosis, therefore the meter and gauge system may not be malfunctioning.
Result
Result Proceed to DTC B132187 is not output A DTC B132187 is output B
Result:
A
REPLACE COMBINATION METER ASSEMBLY. Refer to REMOVAL [08/2021 - ]
Result:
B
See step 6
- CHECK HARNESS AND CONNECTOR (CLOCK ASSEMBLY - COMBINATION METER ASSEMBLY)
- Disconnect the G141 clock assembly connector.
- Disconnect the G17 combination meter assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G141-4 (TX+1) - G17-8 (TX+) Always Below 1 Ω G141-5 (TX-1) - G17-7 (TX-) Always Below 1 Ω Result
Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 7
- CHECK HARNESS AND CONNECTOR (POWER SOURCE - CLOCK ASSEMBLY)
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition G141-1 (B) - Body ground Always 11 to 14 V G141-2 (ACC) - Body ground Engine switch on (ACC) 11 to 14 V Result
Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 8
- Measure the voltage according to the value(s) in the table below.
- CHECK HARNESS AND CONNECTOR (CLOCK ASSEMBLY - BODY GROUND)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G141-6 (E) - Body ground Always Below 1 Ω Result
Proceed to OK NG
Result:
OK
REPLACE CLOCK ASSEMBLY. Refer to REMOVAL [08/2021 - ]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
- Measure the resistance according to the value(s) in the table below.
