DCM Communication Stop Mode [09/2022 - ]: 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 I143 DCM (telematics transceiver) connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition I143-25 (CANP) - I143-26 (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.
*a Front view of wire harness connector
(to DCM (Telematics Transceiver))Standard Resistance
Tester Connection Condition Specified Condition I143-20 (E) - Body ground Cable disconnected from negative (-) auxiliary battery terminal Below 1 Ω - Reconnect the cable to the negative (-) auxiliary battery terminal.
