INSPECTION PROCEDURE

NOTICE:
* Because the order of diagnosis is important to allow correct diagnosis, make sure to begin troubleshooting using How to Proceed with Troubleshooting when CAN communication system related DTCs are output How to Proceed With Troubleshooting.
* After performing repairs, perform the procedure listed in DTC Reproduction Method and confirm that the DTCs are not output again.
* DTC Reproduction Method: Turn the engine switch on (IG) and wait at least 60 seconds.
* After the repair, perform CAN Bus Check and check that all the ECUs and sensors connected to the CAN communication system are displayed Diagnosis System.

PROCEDURE

1. CHECK OPEN IN CAN BUS LINE (YAW RATE SENSOR BRANCH LINE)

(a) Turn the engine switch off.

(b) Disconnect the yaw rate sensor connector.

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





Standard Resistance:





NG -- REPAIR OR REPLACE YAW RATE SENSOR BRANCH LINE OR CONNECTOR (CANH, CANL)
OK -- Continue to next step.

2. CHECK WIRE HARNESS (IG, GND)

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





Standard Resistance:





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

Standard Voltage:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE YAW RATE AND ACCELERATION SENSOR
