9. DRIVE CYCLE I
CAUTION:
Be careful of the state of the battery when performing the DRIVE CYCLE I consecutively. Performing
the DRIVE CYCLE I consecutively without the engine running may cause a low battery voltage and
battery discharge.
NOTE:
• If it is necessary to perform DRIVE CYCLE I consecutively, drive the vehicle under the following conditions
to release accumulated evaporating gas. Performing the DRIVE CYCLE I consecutively without starting the
engine causes a large amount of evaporating gas to accumulate in the canister, which hinders an accurate
diagnosis.
• After engine is warmed up
• Drive for 10 minutes or more at a speed of 48 km/h (30 MPH) or more (duration of drive can be an ac-
cumulation)
• To obtain an accurate diagnostic result, perform the procedures according to the following points.
• Do not refuel gas immediately before performing DRIVE CYCLE I. There will be a large amount of evap-
orating gas immediately after refuel, which may cause a less accurate diagnostic performance.
• Do not shake the vehicle while performing DRIVE CYCLE I. Shaking the vehicle causes evaporating gas
to increase inside the fuel tank, which may cause a less accurate diagnostic performance.
• Do not perform any service operation including installation or removal of parts or connectors while per-
forming DRIVE CYCLE I. Performing service operation could affect on the functions of related parts, which
may cause a less accurate diagnostic performance.
1) Prepare the Subaru Select Monitor kit. <Ref. to EN(H4DOTC)(diag)-8, PREPARATION TOOL, General
2) Prepare PC with Subaru Select Monitor installed.
3) Connect the USB cable to SDI (Subaru Diagnosis Interface) and USB port on the personal computer (ded-
icated port for the Subaru Select Monitor).
NOTE:
The dedicated port for the Subaru Select Monitor means the USB port which was used to install the Subaru
Select Monitor.
4) Connect the diagnosis cable to SDI.
