DCM Communication Stop Mode [12/2019 - 10/2022]: Procedure
WARNING: This page is about a different variant/trim than selected.
- CHECK FOR OPEN IN CAN BUS LINES (DCM (TELEMATICS TRANSCEIVER) BRANCH LINE)
- Disconnect the cable from the negative (-) auxiliary battery terminal.
- Disconnect the H11 DCM (telematics transceiver) connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition H11-25 (CANP) - H11-26 (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 H11-20 (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 H11-1 (+B) - Body ground Ignition switch off 11 to 14 V H11-19 (IG2) - Body ground Ignition switch ON 11 to 14 V Result
Result OK NG
Result:
OK
REPLACE DCM (TELEMATICS TRANSCEIVER)
Refer to REMOVAL [12/2019 - 10/2022]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
- Measure the resistance according to the value(s) in the table below.
