Diagnostic Steps:

1

Use tester to access airbag electronic control unit.

A. Check whether DTC is faulty

2 Inspect

the

battery.

A. Turn the ignition switch to "ON" and measure the battery voltage by universal meter

Standard Voltage: 11-14 V

B. Confirm whether the voltage is at a specified Value.

Refer to 9.2.6.6 Relevant DTC Code Diagnostic

Inspect airbag electronic control unit and its harness connector.

A. Turn the ignition switch to OFF position.

B. Disconnect the battery negative cable and wait for at least 90s.

C. Inspect whether the connector is properly connected to the airbag electronic control unit.

4

Check the harness (Airbag Electronic Control Unit - power supply, Ground).

A. Disconnect the battery negative cable, turn the

ignition switch to OFF position and wait for 90
seconds. Pull down the connector from the airbag
control module.

B. Connect the battery negative cable and wait for at

least 2s.

C. Turn the ignition switch to ON (IG).

D. Measure the voltage between terminal No.30 of

harness connector IP15 and vehicle body ground
with a multimeter.

Standard Voltage: 11-14 V

A. Turn the ignition switch to OFF position .

F. Measure the resistance between terminal No.5 of

harness connector IP15 and vehicle body ground
with a multimeter.
