Navigation Receiver Assembly Communication Stop Mode [09/2013 - ]: Procedure
- PRECAUTION NOTE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the auxiliary battery terminal notice before proceeding with work. Refer to PRECAUTION [09/2013 - ] .
NEXT: Go to next step
- DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
- Disconnect the cable from the negative (-) auxiliary battery terminal before measuring the resistances of the CAN main wire and the CAN branch wire.WARNING:
Wait at least 90 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.
NOTE:When disconnecting the cable, some systems need to be initialized after the cable is reconnected. Refer to INITIALIZATION [09/2013 - ] .
NEXT: Go to next step
- Disconnect the cable from the negative (-) auxiliary battery terminal before measuring the resistances of the CAN main wire and the CAN branch wire.
- CHECK FOR OPEN IN CAN BUS WIRE (NAVIGATION RECEIVER ASSEMBLY CAN BRANCH WIRE)
- Disconnect the navigation receiver assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Switch Condition Specified Condition E119-9 (CANH) - E119-10 (CANL) Power switch off 54 to 69 Ω TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Navigation Receiver Assembly)
NG → REPAIR OR REPLACE NAVIGATION RECEIVER ASSEMBLY CAN BRANCH WIRE OR CONNECTOR (CANH, CANL)
OK: Go to next step
- Disconnect the navigation receiver assembly connector.
- CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - BATTERY AND BODY GROUND)
- Connect the cable to the negative (-) auxiliary battery terminal.NOTE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected. Refer to INITIALIZATION [09/2013 - ] .
- Disconnect the navigation receiver assembly connector.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition E85-4 (+B1) - Body ground Always 11 to 14 V E119-1 (IG) - Body ground Power switch on (IG) 11 to 14 V E85-3 (ACC1) - Body ground Power switch on (ACC) 11 to 14 V - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition E85-7 (GND1) - Body ground Always Below 1 Ω TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Navigation Receiver Assembly)
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 5
- Connect the cable to the negative (-) auxiliary battery terminal.
- REPLACE NAVIGATION RECEIVER ASSEMBLY. Refer to REMOVAL [09/2013 - ]
