DCM Communication Stop Mode [08/2020 -]: Procedure
- CHECK FOR OPEN IN CAN BUS LINES (DCM (TELEMATICS TRANSCEIVER) BRANCH LINE)
- Disconnect the cable from the negative (-) battery terminal.
- Disconnect the G124 DCM (telematics transceiver) connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G124-25 (CANP) - G124-26 (CANN) Cable disconnected from negative (-) 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 G124-20 (E) - Body ground Cable disconnected from negative (-) battery terminal Below 1 Ω *a Front view of wire harness connector
(to DCM (Telematics Transceiver)) - Reconnect the cable to the negative (-) battery terminal.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition G124-1 (+B) - Body ground Always 11 to 14 V G124-19 (IG2) - Body ground Engine switch on (IG) 11 to 14 V Result
Result OK NG
Result:
OK
REPLACE DCM (TELEMATICS TRANSCEIVER). Refer to REMOVAL [08/2020 -]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
- Measure the resistance according to the value(s) in the table below.
