INSPECTION PROCEDURE

NOTICE:
* Turn the ignition switch off before measuring the resistance of the CAN main wire and CAN branch wires.
* 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 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 any triggers related ECU and sensor communication on the CAN, which would cause resistance reading variations.

PROCEDURE

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

(a) Turn the ignition switch off.





(b) Disconnect the yaw rate sensor connector.

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

Standard resistance:

TMC made
TMMK made










NG -- REPAIR OR REPLACE YAW RATE SENSOR BRANCH WIRE 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:

TMC made
TMMK made










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

Standard voltage:

TMC made
TMMK made










NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE YAW RATE AND ACCELERATION SENSOR Removal
