(a) Reconnect the connector for the bus wire that is shorted to +B or GND to the CAN junction connector (the connector that caused the
bus wire resistance to change to 6 kOhms or higher (for +B short) or 200 Ohms or higher (for ground short) when it was disconnected).
(b) Disconnect the connector that includes terminals CANH and CANL from the ECU to which the bus wire shorted to +B or GND is
connected.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

HINT
If the resistance becomes normal when the connector is disconnected from the ECU, there may be a short in the ECU.
NG -- REPAIR OR REPLACE CAN MS BUS BRANCH WIRE OR CONNECTOR
OK -- REPLACE CORRESPONDING ECU
17. CHECK FOR SHORT IN CAN MS BUS WIRES
(a) Disconnect the main body ECU connector.
