the battery ground cable, and wait more than
20 seconds.
2) Disconnect the connector (AB18) from air-
bag control module.
3) Disconnect the connectors (AB59) and
(AB61) under the passenger's seat.
4) Connect the connector (1U) in the test har-
ness U to connector (AB18).
5) Connect the connector (1AB) in the test
harness AB to the connector (AB61).
6) Measure the resistance between connector
(3U) in the test harness U and connector (2AB)
in the test harness AB.

ness.
4CHECK THE AIRBAG HARNESS.
1) Turn the ignition switch to ON.
2) Measure the voltage between connector
(2AB) in the test harness AB and chassis
ground.
Connector & terminal
(2AB) No. 3 — chassis ground:
Is the voltage more than 9 V? Go to step 5.Check the battery
voltage and fuse. If

ment system, whether the correct side is set, type of the DVD-ROM, the existence of any scratches, etc. If
there are no problems on the DVD-ROM, the main body is defective.

C: INSPECTION
NOTE:
•For self diagnosis of the audio system, there is a communications check (communication condition be-
tween the audio and the control panel) and a switch check. Perform a communications check first and make
sure it is operating normally before proceeding to the inspection of switches.
•Complete operations from when the self diagnosis mode of step 1 operates and the buzzer sounds, to
pressing the preset 1 switch in 3., within 15 seconds. If more than 15 seconds pass, a communications error
will be displayed.
•During the diagnosis, do not press the POWER(8), FM(12), AM(14), CD(11), RSE AUX(13) switches.
Pressing these switches will disengage the self diagnosis mode.
