INSPECTION PROCEDURE

NOTICE:
* Turn the ignition switch off before measuring the resistances between CAN bus main wires and between CAN bus branch wires.
* Turn the ignition switch off before inspecting CAN bus wires for a ground short.
* After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not operating.
* Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition switch, any other switches or the doors. If any doors need to be opened in order to check connectors, open the doors and leave them open.

HINT
* Operating the ignition switch, any other switches or a door triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.
* Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring due to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may help determine the cause of the malfunction.

PROCEDURE

1. CHECK CAN BUS WIRE (YAW RATE SENSOR SUB BUS LINE DISCONNECTION)

(a) Turn the ignition switch off.





(b) Disconnect the yaw rate sensor connector (D28).

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

Standard resistance:





NG -- REPAIR OR REPLACE YAW RATE SENSOR SUB BUS LINE OR CONNECTOR
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 Removal (from 12/2010)
