- Check CAN Bus Lines for Short Circuit (Continued)

6. CHECK FOR SHORT IN CAN BUS LINES (CAN NO. 2 J/C - YAW RATE AND ACCELERATION SENSOR)

(a) Disconnect the wire harness connector from the CAN No. 2 junction connector front side.

(b) Disconnect the yaw rate and acceleration sensor connector.

(c) Measure the resistance according to the value(s) in the table below.





Standard Resistance:

NG -- REPAIR OR REPLACE CAN BRANCH LINE OR CONNECTOR (CAN NO. 2 J/C - CERTIFICATION ECU)
OK -- Continue to next step.

10. CHECK FOR SHORT IN CAN BUS LINES (CAN NO. 2 J/C)

(a) Reconnect the wire harness connector to the CAN No. 2 junction connector front side and rear side.

(b) Measure the resistance according to the value(s) in the table below.





Standard Resistance:

NOTICE:
* The resistance must be measured after the main line connected ECUs (ECM and combination meter assembly), CAN No. 1 junction connector, CAN No. 2 junction connector and CAN No. 3 junction connector are reconnected.
* The resistance must be measured after the CAN No. 2 junction connector branch line connected ECU and sensor connectors are disconnected.

NG -- REPLACE CAN NO. 2 JUNCTION CONNECTOR
OK -- Continue to next step.
