INSPECTION PROCEDURE
NOTICE:
* Turn the ignition switch off before measuring the resistances of the CAN main wire and the CAN branch wire.
* After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.
* 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.
* Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT
* Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
PROCEDURE
1. CHECK CAN BUS LINE FOR DISCONNECTION (YAW RATE SENSOR BRANCH WIRE)
(a) Turn the ignition switch off.
(b) Disconnect the D81 yaw rate sensor connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (IG, GND)
(a) Disconnect the D81 yaw rate sensor connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
