bag control module.
3) Connect the connector (1U) in the test har-
ness U to connector (AB6).
4) Connect the battery ground terminal and
turn the ignition switch to ON.
5) Measure the voltage between connector
(2U) in the test harness U and chassis ground.

(without any cancel operations), DTC will be dis-
played on the screen after selecting the {Check
Cancel Code} and pressing the [YES] key on the
engine malfunction diagnosis screen.
CAUTION:
•When performing diagnosis, observe the le-
gal speed limit on the road.
•DTC will be also displayed when cruise con-
trol is cancelled by driver. Do not confuse them.
•Get an assistant in the vehicle for help of di-
agnosis while driving.
NOTE:
DTC will be cleared by turning ignition switch or
cruise control main switch to OFF.

1) Connect the Subaru Select Monitor.
2) Turn the ignition switch and cruise control main
switch to ON.
3) Turn the Subaru Select Monitor switch to ON.
4) On the «Main Menu», select the {2. Each Sys-
tem Check} and press the [YES] key.
5) On the «System Selection» display screen, se-
lect the {Engine} and press the [YES] key.
