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.
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 F34 yaw rate sensor connector.

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

Standard resistance:

(d) Reconnect the yaw rate sensor connector.

NG -- REPAIR OR REPLACE CAN BRANCH WIRE CONNECTED TO YAW RATE SENSOR (CAN-H, CAN-L)
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (IGSW, E1)

(a) Disconnect the F34 yaw rate sensor connector.

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

Standard resistance:

(d) Reconnect the yaw rate sensor connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE YAW RATE SENSOR Removal
