EN(H4DOTC)(diag)-60 Drive Cycle ENGINE (DIAGNOSTICS) 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. • 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).
