CHECK AIRBAG REAR HARNESS (CUR-
TAIN AIRBAG SENSOR HARNESS LH).
1) Turn the ignition switch OFF, disconnect the
battery ground cable, and wait more than 20
seconds.
2) Disconnect the connector (AB21) from seat
belt pretensioner (LH).
3) Disconnect the connector (AB19) from side
airbag module (LH).
4) Disconnect the connector (AB31) from
(AB39).
5) Disconnect the connector (AB17) from air-
bag control module.
6) Connect the connector (1U) in the test har-
ness U to connector (AB17).
7) Disconnect the connector (AB32) from cur-
tain airbag sensor (LH), and connect the con-
nector (2V) in test harness V to connector
(AB32).
8) Measure the resistance between connector
(5U) in the test harness U and connector (3V)
in the test harness V.

Y: DTC 58 CURTAIN AIRBAG SENSOR RH FAILURE
DTC DETECTING CONDITION:
Curtain airbag sensor (RH) is faulty.
If DTC 58 is displayed, the circuit within the curtain airbag sensor (RH) is faulty. Replace the curtain airbag
sensor (RH). <Ref. to AB-24, Curtain Airbag Sensor.>
Z: DTC 59 CURTAIN AIRBAG SENSOR LH FAILURE
DTC DETECTING CONDITION:
Curtain airbag sensor (LH) is faulty.
If DTC 59 is displayed, the circuit within the curtain airbag sensor (LH) is faulty. Replace the curtain airbag
sensor (LH). <Ref. to AB-24, Curtain Airbag Sensor.>
Diagnostic Chart with Trouble Code
Is the resistance less than 10
Ω?
Is the resistance more than 1
MΩ?

Go to step 2.
Replace the cur-
tain airbag sensor
(LH). <Ref. to AB-
24, Curtain Airbag
Sensor.> When
the sensor is not
OK though the
sensor is replaced,
replace the airbag
control module.
<Ref. to AB-22,
