*a Front view of wire harness connector
(to DCM [Telephone Transceiver Assembly]) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G9-15 (CANP) - G9-16 (CANN) Cable disconnected from negative (-) auxiliary battery terminal 54 to 69 Ω Result
Proceed to OK NG
Result:
NG
REPAIR OR REPLACE CAN BRANCH WIRE OR CONNECTOR
Result:
OK
See step 2
- CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G9-4 (E) - Body ground Cable disconnected from negative (-) auxiliary battery terminal Below 1 Ω *a Front view of wire harness connector
(to DCM [Telephone Transceiver Assembly]) - Reconnect 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 [02/2019 - 10/2019]
