- CHECK FOR OPEN IN CAN BUS LINES (DCM (TELEMATICS TRANSCEIVER) BRANCH LINE)
- Disconnect the cable from the negative (-) auxiliary battery terminal.
- Disconnect the G10 DCM (telematics transceiver) connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G10-15 (CANP) - G10-16 (CANN) Cable disconnected from negative (-) auxiliary battery terminal 54 to 69 Ω *a Front view of wire harness connector
(to DCM (Telematics Transceiver))Result
Result OK NG
Result:
NG
REPAIR OR REPLACE CAN BRANCH LINES OR CONNECTOR (DCM (TELEMATICS TRANSCEIVER))
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 G10-4 (E) - Body ground Cable disconnected from negative (-) auxiliary battery terminal Below 1 Ω *a Front view of wire harness connector
(to DCM (Telematics Transceiver)) - Reconnect the cable to the negative (-) auxiliary battery terminal.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition G10-1 (+B) - Body ground Power switch off 11 to 14 V G10-7 (IG2) - Body ground Power switch on (IG) 11 to 14 V G10-8 (ACC) - Body ground Power switch on (ACC) 11 to 14 V Result
Result OK NG
Result:
OK
REPLACE DCM (TELEMATICS TRANSCEIVER). Refer to REMOVAL [06/2018 - 10/2019]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
- Measure the resistance according to the value(s) in the table below.
