NOTICE:
*
The resistance must be measured after the main wire connected ECUs (ECM and combination meter), CAN No. 1 junction
connector and No. 2 junction connector are reconnected.
*
The resistance must be measured after the CAN No. 2 junction connector branch wire connected ECU and sensor connectors are
disconnected.
NG -- REPLACE CAN NO. 2 JUNCTION CONNECTOR
OK -- Continue to next step.
19. CHECK FOR SHORT IN CAN BUS WIRES (ECU, SENSOR)
(a) Connect the probes of an ohmmeter to terminals 6 (CANH) and 14 (CANL) of the DLC3.

(b) While observing the resistance value shown on the ohmmeter, reconnect each ECU and sensor connector until the resistance becomes
abnormal (Below 54 Ohms).
HINT
If the resistance becomes abnormal when an ECU connector is reconnected, there may be a short in the ECU.
NEXT -- REPLACE CORRESPONDING ECU OR SENSOR
20. CHECK FOR SHORT IN CAN BUS WIRES (COMBINATION METER)
