Inspection of BCM and its CircuitsS7RS0BA204018
BCM and its circuits can be checked at BCM wiring couplers by measuring voltage and resistance.
CAUTION!
BCM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to BCM
with couplers disconnected from it.
Voltage Check1) Disconnect negative (–) cable at battery.
2) Remove BCM (included in junction block assembly) refe rring to “BCM (Included in Junction Block Assembly)
Removal and Installation”.
3) Connect connectors to BCM (1) and junction block assembly (2).
4) Check voltage at each terminal number of couplers connected. For connector and terminal number, refer to “Connector Layout Diagram of BCM and Junction Block Assembly”.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when
ignition switch is ON.
• Voltage with asterisk (*) can not be measured by voltmeter because it is pulse signal. Check it with oscilloscope if necessary.
